What Is an IPv6 Private Network?
IPv6 private networks are IPv6 Enhanced-based dedicated networks built on top of IPv6 network infrastructure for industries as well as medium- and large-sized enterprises.
An IPv6 private network features reliable connections, quality assurance, flexible slicing, intelligent Operations and Maintenance (O&M), and security and reliability. It is service-oriented and application-aware, and can support future innovative technologies and enhanced network capabilities, facilitating industry digital construction and promoting social and economic development.
IPv6 private networks can be constructed by industries or enterprises, or constructed by telecom carriers and provided for industries or enterprises as a service.
Why Do We Need IPv6 Private Networks?
Challenges Faced by Traditional Industry Private Networks
Private networks are oriented to users in specific industry sectors, such as government, education, healthcare, electric power, and transportation. Compared with public communication networks, which are constructed and operated by telecom carriers, private networks have the following advantages:
- Security isolation: Private networks provide higher data security. Dedicated network communication channels and encryption technologies are used to prevent data from being stolen, tampered with, or damaged during transmission. Private networks also provide higher-level security protection for sensitive business data, public service data, personal privacy information, and more.
- Quality assurance: Private networks can provide high-quality network services based on the requirements of different industries, meeting needs in terms of bandwidth, delay, packet loss, and reliability assurance. By configuring network devices with parameters, it is possible to provide network services that better meet industry service application requirements. Different levels of reliability protection can be implemented through port, device, and network redundancy based on industry requirements. For example, multiple network planes can be configured for enterprise production services to ensure that services are not interrupted.
- Customizability: Private networks can be customized to meet the special requirements of industry customers. For example, industry customers may want to provide key assurance and real-time monitoring (such as key video conference assurance) for a certain type of service to meet office or emergency command requirements, or isolate a certain type of service from other services for improved security.
- O&M: Due to the private attributes of industry private networks, private networks are less complex than public communication networks in aspects such as system interconnection, service provisioning and deployment, quick fault locating, and self-healing.
Currently, industry private networks usually use Synchronous Digital Hierarchy (SDH) networks or traditional IPv4 networks. The devices on such networks are outdated, power-hungry, bulky, and difficult to operate and maintain. As a result, the networks cannot meet the development requirements of new services. SDH networks or traditional IPv4 networks have the following drawbacks:
- SDH networks support only rigid pipes and do not provide statistical multiplexing. As such, the networking is inflexible. The bandwidth of SDH networks is also low (2 Mbit/s, 155 Mbit/s, or 622 Mbit/s), far below that required by high-bandwidth services (10 Gbit/s or 100 Gbit/s). In addition, as there is no potential for SDH to continue evolving, live-network SDH devices are gradually being retired.
- Traditional IPv4 networks do not support the new technologies and capabilities of IPv6 Enhanced, such as Segment Routing over IPv6 (SRv6), network slicing, In-situ Flow Information Telemetry (IFIT), and Application-aware IPv6 Networking (APN6). Network resources are shared, and so there is no guarantee for bandwidth and delay. Worse yet, the networks cannot carry large-bandwidth or delay-sensitive services, and suffer from complex O&M and slow service provisioning.
- The networks do not support one-hop cloud access. Cloud resources and networks are separated and cannot be converged, failing to meet enterprises' requirements for quick cloudification in digital transformation.
The following table describes the service challenges faced by some traditional industries in the gradual digitalization phase. Based on these challenges, it can be seen that traditional industry private networks need to be comprehensively upgraded in terms of coverage, differentiated assurance, security and reliability, and O&M.
Industry |
Service Challenge |
---|---|
Government |
Insufficient coverage at the grassroots level in towns: e-Government extranets need to improve services to complete coverage at all levels from provinces to villages. Difficult to assure key services: Video conferencing and video command require networks to provide key assurance capabilities in order to prevent frame freezing and detect faults in advance. |
Education |
Difficult to migrate services to multiple clouds: Services involve multiple clouds such as the private cloud of the education bureau, industry cloud for higher vocational training, and public cloud. As a result, service rollout can take as long as 15 days. Difficult to guarantee differentiated requirements: AR/VR classrooms require 2.5 Gbit/s bandwidth, and higher vocational training requires an industry cloud with less than 50 ms delay. |
Healthcare |
Large amount of data to be transmitted: Transmitting HD medical images requires a bandwidth of more than 300 Mbit/s. Difficult to meet high service quality requirements: Medical insurance settlement services require an ultra-low bit error rate (BER) and a jitter of no more than 2 ms. |
Electric power |
Difficult to meet zone-based power management requirements: Services in zones I, II, III, and IV require bandwidth assurance, security isolation, zero interference to production services, and a relay protection delay of less than 30 ms. Insufficient reliability: The network reliability must be greater than 99.999% to ensure uninterrupted production services. |
Transportation |
Insufficient bandwidth: Video perimeter security protection requires a 10GE data network. Excessive delay: Over-the-horizon train services require a network delay of less than 150 ms. Insufficient reliability: Train dispatching services require the network reliability to be greater than 99.999%. |
Industry Requirements for New Private Networks
Different industries have different requirements on private networks. To carry services, an advanced, efficient, secure, reliable, elastic, and agile private network is needed in order to meet the following basic requirements:
- Wide IP coverage: The private network must provide high bandwidth and GE/10GE terminal access to cover all industry branches. It must also provide a range of access modes, such as optical fiber, 5G, and Wi-Fi access.
- Differentiated assurance: Network resources need to be rigidly isolated between industries or between different services in an industry to implement exclusive use of resources. This can help ensure the Service Level Agreement (SLA) of high-value industries or services.
- Security: Industry private network service data is isolated from external data to prevent industry data leakage.
- Reliability: The simplified network architecture and reliable network devices provide reliability, redundancy, and fault tolerance capabilities.
- Cloud resource sharing: Cloud resources are shared by industries and enterprises on the private network, meeting service cloudification requirements.
- Fast service provisioning: New services can be quickly provisioned on demand.
- High expandability: The network supports the access of terminals of multiple service types as well as elastic network scaling. It also allows network applications to be continuously added and optimized, and provides various service scheduling and expansion capabilities.
- Simple O&M: Industry customers are typically weak in O&M capabilities. This requires the network to have automatic and visualized O&M capabilities.
Emergence of IPv6 Private Networks
As industry sectors such as government, education, healthcare, electric power, and transportation undergo digitalization, IPv6 private networks emerge to meet the corresponding requirements such as wide IP coverage, high security, service isolation, application awareness, differentiated services, and network servitization.
IPv6 private networks are IPv6 Enhanced-based dedicated networks built on top of IPv6 network infrastructure for industries as well as medium- and large-sized enterprises. They feature flexible connections, quality assurance, flexible slicing, intelligent O&M, and security and reliability.
As shown in the following figure, an IPv6 private network can be divided into three layers by network scale: access layer, aggregation layer, and core layer. Traffic is aggregated layer by layer. In terms of protocols, SRv6 and Ethernet Virtual Private Network (EVPN) are used to unify the network protocol stack. Meanwhile, network slicing is used to provide logical networks with differentiated services at multiple levels, including industries, services, and users, implementing optimal scheduling for these different levels. In terms of devices, enterprise-side Customer-Premises Equipment (CPE) is also a key node on an IPv6 private network and needs to be upgraded to support IPv6, implementing E2E SRv6 deployment. The intelligent management and control system manages access routers (including enterprise CPEs), aggregation routers, and core routers, and SRv6 is enabled on the routers. The intelligent management and control system automatically configures and optimizes E2E SRv6 services.
IPv6 private network
IPv6 private networks can be constructed by industries or enterprises, or constructed by telecom carriers and provided for industries or enterprises as a service. When telecom carriers construct IPv6 private networks, they are responsible for providing construction and maintenance services for industries or enterprises. This saves industries or enterprises from having to construct and maintain the networks themselves.
Architecture and Key Technologies of an IPv6 Private Network
With the advantages of the IPv6 Enhanced technology system in aspects such as flexible network programming, slice isolation, elasticity and agility, IFIT, and security and reliability, IPv6 private networks can meet the specific requirements of different industries. The following figure shows the innovative technical architecture of an IPv6 private network.
Innovative technical architecture of an IPv6 private network
An IPv6 private network consists of the intelligent network management and control system, transport network, and access terminals. The transport network can be divided into multiple logical network slices through slicing technology, meeting the resource isolation requirements of some services on the industry private network. In terms of technical architecture, the IPv6 private network can be divided into four layers — basic protocol, service assurance, network service, and intelligent management and control — implementing network flexibility and scalability.
- Basic protocol layer: SRv6 simplifies and unifies network protocols. This is the basis for constructing an intelligent IP network. SRv6 combines the advantages of the source routing mechanism used in Segment Routing (SR) along with the simplicity and extensibility of IPv6. In addition, SRv6 provides a multi-dimensional programming space. SRv6 is used as a basic network protocol, with no need to deploy traditional label protocols such as Multi-protocol Label Switching (MPLS) Label Distribution Protocol (LDP) and Resource Reservation Protocol (RSVP). With native IPv6-based connection capabilities, it provides traditional underlay connections and one-hop overlay connection capabilities similar to Software-Defined Wide Area Network (SD-WAN), meeting different kinds of service connection requirements.
- Service assurance layer: Routers support various Operations, Administration and Maintenance (OAM) detection protocols, such as Seamless Bidirectional Forwarding Detection (SBFD), Two-Way Active Measurement Protocol (TWAMP), and IFIT. SRv6 supports Hot Standby (HSB), Topology-Independent Loop-Free Alternate (TI-LFA), and microloop avoidance. Working with OAM detection protocols, SRv6 can implement 50 ms convergence in any fault scenario. This significantly improves network reliability and provides highly reliable service assurance capabilities for IPv6 private networks.
- Network service layer: Based on rich IPv6 extension headers and innovative IPv6 Enhanced technologies, this layer provides different network service assurance for IPv6 private networks. For example:
- IPv6 reachability and route summarization capabilities are used to implement efficient and fast E2E cross-domain service provisioning.
- APN6 technology is used to match service requirements with network capabilities. APN6 conveys APN attributes (including APN IDs and parameters for identifying applications and network performance requirements, respectively) to a network by leveraging the extension header space in IPv6 packets. This enables service providers to provide fine-grained network services and achieve precise network O&M. Paired with other technologies, such as SRv6 and network slicing, APN6 enables a network to provide increasingly diversified network services in order to meet the differentiated requirements of applications.
- IP network slicing is used to meet differentiated service assurance and security isolation requirements of applications. Network slicing is a new network architecture that provides multiple logical networks on the same shared network infrastructure. Each logical network serves a specific service type or industry user. It is possible to define the logical topology, SLA requirements, reliability, and security level of each network slice as needed, thereby meeting the differentiated requirements of services, industries, and users. With network slicing, carriers can reduce the cost compared to constructing multiple private networks and provide highly flexible network services that can be scheduled and allocated on demand based on service requirements. This allows carriers to glean more value from their networks for improved monetization, and also facilitates the digital transformation of various industries.
- IFIT can be used to implement real-time quality monitoring at the flow level for certain services, implement E2E SLA visualization, and automatically demarcate and locate faults. IFIT adds IFIT headers to real service packets to mark the characteristics of the packets. This helps to measure network performance indicators, such as delay, packet loss rate, and jitter. IFIT uses telemetry technology to send measurement data in real time and displays measurement results on the graphical user interface (GUI) of a network controller. Compared with traditional network O&M technologies, IFIT features high precision, real-time performance, and visualization.
- Intelligent management and control layer: The network digital map provides capabilities such as network status awareness, network risk prediction, automatic fault analysis, and automatic problem closure to implement intelligent network O&M and automatic network quality management. The network digital map uses navigation map-based human–machine interaction, reconstructing network O&M experience.
- Visualization (eyes-free): network status convergence awareness and holographic visualization. A unified visualized map is used to display data at layers (such as the physical layer, network layer, slicing layer, routing layer, service layer, and application layer) of an IP network in real time, helping customers easily know the network status.
- Insight (brain-free): advanced network risk prediction and automatic network fault analysis. In-depth analysis is performed on data at each network layer. This includes network impact analysis before configuration changes, Border Gateway Protocol (BGP) route security analysis, and network fault root cause analysis. Network handling suggestions are also provided.
- Optimization (hands-free): automatic network problem closure, process automation, network status change detection, and closure optimization. For example, path adjustment is performed when network traffic congestion occurs, SLA assurance is performed for virtual private network (VPN) services with poor quality of experience (QoE), and routing acceleration is performed in response to users' requirements for private line acceleration.
Advantages of an IPv6 Private Network
The IPv6 industry private network constructed based on the IPv6 Enhanced technology system uses SRv6 to provide fast service provisioning capabilities. It uses network slicing to provide multiple planes for carrying different services of industries, implementing low-cost, secure isolation, and high-quality differentiated service assurance capabilities. The network also uses IFIT and the network digital map to provide hierarchical network views, intelligent fault locating and demarcation, and low operating expense (OPEX) capabilities, thereby providing next-generation digital infrastructure for industries such as smart government, telemedicine, online education, smart city, and financial securities.
As shown in the following figure, the IPv6 private network is advanced in six aspects: wide IP coverage, service isolation, high security, differentiated services, network servitization, and application awareness.
Advantages of an IPv6 private network
The following describes the advantages and necessity of the IPv6 private network based on some industry applications.
- Wide IP coverage. SRv6 is a native IPv6-based protocol that helps quickly provision services. The IPv6 private network uses SRv6 and Ethernet VPN (EVPN) technologies to simplify control protocols into an Interior Gateway Protocol (IGP) and Border Gateway Protocol (BGP), and uses IPv6 as the service transport protocol. In industry scenarios such as smart city and smart government, the IPv6 private network can provide ultra-large-scale networking, ubiquitous terminal connections, and simplified service configurations. On a traditional IP network, cross-domain services need to be configured segment by segment and hop by hop. Instead, on the IPv6 private network, the services need to be configured only at both ends and can be provisioned in one-hop mode.
- Service isolation. On a traditional IP network, forwarding resources are shared. Bursts of different services cause interference, affecting service jitter and delay. For services that require resource isolation in industry policies — such as video conferencing and video security — the IPv6 private network is capable of network slicing and provides E2E slicing resources, ensuring that indicators such as bandwidth, delay, jitter, and packet loss meet requirements.
- High security. On a traditional IP network, service security uses policy-based routing (PBR) and complex redirection policies to forward service flows to different security devices, resulting in poor scalability. In addition, static policy configurations cannot meet the dynamic scaling requirements of cloud-based security devices. The IPv6 private network can use the SRv6 Service Function Chaining (SFC) technology along with security cloud service capabilities to quickly customize security policies for each service and dynamically adjust the policy execution of security services in the cloud through the management and control platform. Besides, the IPv6 private network can provide dedicated slices for services with high security requirements through network slicing to ensure security isolation of the services. For services such as government big data, urban Internet of Things (IoT), and finance, the IPv6 private network uses flexible SRv6 SFC policies to provide security value-added service capabilities that can be flexibly customized and elastically scaled.
- Differentiated service. A traditional IP network uses a distributed model. Packet forwarding depends on routing protocols or complex resource reservation protocols, making it difficult to provide E2E differentiated services. For delay-sensitive services such as telemedicine and securities trading, the IPv6 private network can use a centralized intelligent management and control system to collect network path delay and bandwidth information for multi-factor path planning. For such services, the IPv6 private network provides path planning with the lowest delay, fully addressing fiber network detour problems. In addition, when the network path delay deteriorates or the bandwidth cannot meet the requirement, the path can be quickly replanned and switched.
- Network servitization. The planning and O&M of a traditional IP network have high technical requirements on personnel. And as the network continues to scale, network O&M becomes more and more difficult. The IPv6 private network uses the digital twin technology to provide navigational human–machine interaction O&M experience. Network capabilities are provided as services for industry customers, greatly simplifying network O&M.
- Application awareness. On a traditional IP network, specific applications are marked based on the IP 5-tuple. For example, the IP address of an over the top (OTT) resource server is obtained in advance to identify the traffic generated when a user accesses the corresponding OTT resources. This application identification mode requires an application's IP address to be updated in real time, and is therefore difficult to deploy on the network. For services such as government conferencing and key video conference assurance, the IPv6 private network provides APN6 technology to communicate with the device side. It can also use deep flow analysis (DFA) cards on devices to identify video quality and provide identification, awareness, and assurance capabilities for key services.
In addition to the preceding advanced features, the IPv6 private network can continuously provide innovative technologies and enhanced network capabilities based on the development of industry services, facilitating industry digital construction and promoting social and economic development.
Applications of an IPv6 Private Network in Industries
Currently, IPv6 private networks have been widely used in a range of industries, such as government, education, healthcare, electric power, and transportation. The following describes IPv6 private networks in these industries.
IPv6 Government Private Network
IPv6 technology helps digital governments deploy government services over the Internet to achieve vertical linkage, department collaboration, and service orientation. Based on IP network slicing, a forward-looking, full-coverage, secure, and smart multi-plane digital government network is built to deliver differentiated experience for different services. The network is hyper-converged, hyper-connected, and service-oriented, integrating cloud, network, and security. The government extranet has three major requirements: service isolation, easy provisioning, and intelligent O&M. It needs to support independent transport of each service, one-hop cloud access, agile networking, and intelligent O&M functions such as service visualization and quick fault locating.
The following figure shows the architecture of the IPv6 government private network. This architecture uses IP network slicing to isolate services on the government extranet. Each department or service exclusively uses a logical network slice so that services do not interfere with each other. This meets security and reliability requirements and ensures service experience. SRv6 is used to implement one-hop cloud access and easy networking. E2E networking and automatic and fast provisioning of cloud access services enable intensive service migration to the cloud and automatic service provisioning. Intelligent O&M supports global topology display, service SLA visualization, real-time dynamic monitoring, and quick fault locating, improving service experience.
IPv6 government private network
The construction of the IPv6 government extranet enables service interconnection and interworking among multiple departments, facilitates information sharing, and eliminates service barriers. In addition, the IPv6 government extranet enables interconnection and assistance between governments and departments at all levels to improve the work efficiency of departments. Citizens can make reservations and handle services online, expediting service handling and saving public resources.
IPv6 Education Private Network
The education private network needs to carry multiple services, such as Internet, financial management, electronic inspection, video security, and physical and chemical examination. Hard slice isolation is required for high-value services. With the examination service, for example, the examination data must be absolutely secure and videos must be smooth, with no lag. Specifically, the security, reliability, and real-time performance of the service must be ensured.
The following figure shows the deployment solution of the IPv6 education private network. This solution uses technologies such as IP network slicing and SRv6 Policy to isolate service data such as security data and conference videos in examination centers from the Internet, ensuring secure transmission and preventing data leakage. SRv6 one-hop cloud access enables users to quickly access the examination private cloud. IFIT visualizes the network topology and network SLA indicators to ensure the reliability of services such as video security, examination center security, and smart classroom.
IPv6 education private network
IPv6 Healthcare Private Network
IPv6 private networks are well poised to facilitate digital transformation of smart healthcare, especially in the scenarios such as telemedicine and medical image sharing.
- Telemedicine manipulation services mainly include remote surgery and remote first aid. They feature low bandwidth, deterministic low delay, high reliability, and high security. The bandwidth required by such services is typically no more than 20 Mbit/s, and the strictest E2E unidirectional delay is less than 20 ms. This ensures that medical accidents are not resulted from communication reasons in the scenarios such as surgery and first aid.
- Medical images play an important role in patient diagnosis. Online image check appointment and online report query services are provided. Image data of hospitals needs to be shared to support telemedicine. The access bandwidth of these services is generally no less than 100 Mbit/s. They feature high bandwidth, high security, and visualized and manageable service experience.
The following figure shows the deployment solution of the IPv6 healthcare private network. This solution brings the following benefits:
- Flexible connections: Hospitals at all levels are interconnected to quickly and conveniently connect to multiple clouds. Medical data can be uploaded and shared in a timely manner. Combining medical alliance, cloudification, and telemedicine accelerates information sharing and resource collaboration in the healthcare industry.
- Differentiated assurance: Flexible slicing based on different types of medical services achieves differentiated transport assurance with low delay and high bandwidth. This solution uses IP network slicing to provide telemedicine slices with deterministic low delay and medical image slices with high bandwidth, ensuring differentiated transport, deterministic experience, and service isolation.
- Intelligent O&M: IFIT is used to implement quick provisioning, visualized services, and quick fault locating, meeting the requirements of visualized and manageable service experience. Link information is collected in seconds, and service quality such as packet loss and delay is displayed in real time. In addition, faults can be rectified in minutes, ensuring user service experience.
- Multiple value-added services: Home diagnosis and treatment, video diagnosis and treatment, health consultation, and other value-added services improve the service level.

IPv6 Electric Power Private Network
Smart grids have become a focal point for the development of the electric power industry. As such, countries around the world are formulating plans and policies to accelerate the development of smart grid technologies and the industry. Leveraging advanced Information and Communication Technologies (ICTs), smart grids build reliable, high-speed, and two-way communication channels. Smart grids also employ sensing and measurement technologies and devices, as well as control methods, to ensure secure, economical, efficient, and eco-friendly operations. With the construction of smart grids and digital substations, more and more services — such as supervisory control and data acquisition (SCADA) and dispatch phone — are becoming IP-based. As well as this, new services — such as wide area measurement system (WAMS) and wide area protection — are being continuously introduced. Meanwhile, power grids are seeing the large-scale emergence of new energy services such as distributed power generation, energy storage, and charging piles, while high-bandwidth services such as video security continue to grow. With so many evolving and newly emerging technologies, traditional communication networks are unable to meet the requirements of smart grids.

In addition to the preceding production dispatching services, there are some office management services, such as video conferencing, administrative telephone, office automation (OA), management information system (MIS), Internet, and mobile office. These services also require bandwidth guarantee and isolated transport.
In general, the IPv6 private network supported by IPv6 Enhanced technologies — such as SRv6, IFIT, and network slicing — is the best choice for the next-generation intelligent electric power data network.
The following figure shows the deployment solution of the IPv6 electric power private network. This solution brings the following benefits:
- Intelligent connection: SRv6 is used for one-hop service access to the cloud, automatic network provisioning, and simplified deployment. EVPN is used to carry IPv4 and IPv6 services in a unified manner, accelerating the rollout of new IPv6 services.
- Deterministic assurance: Flexible Ethernet (FlexE) network slicing enables differentiated transport of production and key office services, hard isolation of services, independent queues for key services, 100% bandwidth guarantee, and controllable jitter.
- Intelligent O&M: Fast fault locating is implemented using IFIT, key performance indicators (KPIs) are displayed hop by hop, and network-wide visualization is implemented. Intelligent fault analysis and quick fault locating support normal running of service systems and ensure good user experience.

Traditional transportation operation networks face the following issues:
- Insufficient bandwidth: Trackside surveillance and station surveillance bring 10-fold increase in video traffic volume, innovative services are migrated to the cloud, and data is stored on the cloud, yet the bandwidth of traditional networks is insufficient.
- Insufficient reliability: The IP data communication network carries production services and cannot provide full-process protection. Multiple services are converged, and the E2E SLA cannot be guaranteed.
- Low O&M efficiency: The networks for vehicles, stations, depots, and railway bureaus are fully connected, resulting in 100 times more complex connections. As a result, problem demarcation is difficult and takes several days, and service quality cannot be visualized in real time.
The following figure shows the deployment solution of the IPv6 transportation private network. This solution brings the following benefits:
- Wide IP coverage: The upstream bandwidth of stations is upgraded to 10 Gbit/s. Moreover, SRv6 enables refined service management and intelligent path computation.
- Service isolation: FlexE network slicing is used to carry railway services, implementing rigid isolation between services. The slice bandwidth can be flexibly changed based on service development to meet SLA requirements and ensure private network-level experience.
- Intelligent O&M: IFIT accurately obtains the SLA information of service packets on each node or link, visualizing the network in real time from multiple dimensions and locating faults in minutes. The controller uses technologies such as SRv6 to quickly adjust service paths.
