Utilizing existing IPv6 forwarding technology, SRv6 implements network programming through flexible IPv6 extension headers. SRv6 reduces the number of required protocol types, offers great extensibility and programmability, and meets the diversified requirements of more new services. It also provides high reliability and offers exciting cloud service application potential.

WiFi 7 (Wi-Fi 7) is the next-generation Wi-Fi standard to be launched, also known as IEEE 802.11be — extremely high throughput (EHT). Based on Wi-Fi 6, Wi-Fi 7 introduces technologies such as 320 MHz bandwidth, 4096-quadrature amplitude modulation (QAM), multi-resource unit (RU), multi-link operation (MLO), enhanced multi-user multiple-input multiple-output (MU-MIMO), and multi-access point (AP) coordination. Drawing on these cutting-edge technologies, Wi-Fi 7 delivers a higher data transmission rate and lower latency than Wi-Fi 6. Wi-Fi 7 is expected to support a throughput of up to 30 Gbps, about three times that of Wi-Fi 6.

An artificial intelligence (AI) firewall, a next-generation product of a next-generation firewall (NGFW), uses intelligent detection technologies to improve the capability of detecting advanced threats and unknown threats. The NGFW uses a static rule database to detect threats, which is difficult to cope with advanced threats of variants. The AI firewall uses the intelligent detection engine to train threat detection models based on massive samples and continuously optimize the models based on real-time traffic data, improving threat detection capabilities.

Wi-Fi 6, also known as 802.11ax, is the latest Wi-Fi industry standard after Wi-Fi 5 (802.11ac). Before the release of Wi-Fi 6, Wi-Fi standards were identified by versions from 802.11b to 802.11ac. Later, the Wi-Fi Alliance decided to make the Wi-Fi standards easier to understand and remember, and therefore renamed them in a manner similar to the different generations like 3G, 4G, and 5G in mobile communications. Wi-Fi 6 introduces various new technologies, such as orthogonal frequency division multiple access (OFDMA), uplink/downlink multi-user multiple-input multiple-output (UL/DL MU-MIMO), BSS coloring, and Target Wake Time, significantly improving performance. In this manner, Wi-Fi 6 supports four times higher bandwidth and concurrency than Wi-Fi 5. Additionally, Wi-Fi 6 provides lower latency and better energy-saving capability than Wi-Fi 5.

Internet Protocol version 6 (IPv6), also called IP Next Generation (IPng), is a second-generation standard network layer protocol. The network layer where IPv6 resides provides connectionless data transmission services. IPv6 is designed by the IETF as an upgraded version of IPv4 and addresses many defects in IPv4. The most significant difference between IPv6 and IPv4 is that IP addresses are lengthened from 32 bits to 128 bits. IPv6 is more competitive in future markets with its simplified header, sufficient address space, hierarchical address structure, flexible extension header, and enhanced neighbor discovery mechanism.

802.11ac is the fifth-generation 802.11 standard and is also known as Wi-Fi 5 (or WiFi 5). Through various technological innovations, 802.11ac achieves a qualitative leap in the wireless transmission rate — from 600 Mbit/s supported in 802.11n to 6.93 Gbit/s, bringing infinite possibilities for more application scenarios that depend on heavy-traffic wireless transmission. Currently, 802.11ac has been widely used in wireless network communication for enterprises and homes, which greatly changes the way we work and live.

WiFi, also known as Wi-Fi, is a trademark owned by the Wi-Fi Alliance (WFA). It is a WLAN technology based on the IEEE 802.11 family of standards. Since the release of the first-generation IEEE 802.11 standard in 1997, it has been evolved to the latest 6th-generation 802.11ax standard (Wi-Fi 6). Before the release of Wi-Fi 6, Wi-Fi standards were identified by versions from 802.11b to 802.11ac. Later, the WFA decided to make the Wi-Fi standards easier to understand and remember for Wi-Fi users and device vendors, and therefore renamed the standards using generational numbering.

What Is VXLAN? A Mainstream Tunneling Technology
VXLAN, or Virtual Extensible LAN, is a network virtualization technology widely used on large Layer 2 networks. VXLAN establishes a logical tunnel between the source and destination network devices, through which it uses MAC-in-UDP encapsulation for packets. Specifically, it encapsulates original Ethernet frames sent by a VM into UDP packets. It then encapsulates the UDP packets with the IP header and Ethernet header of the physical network as outer headers, enabling these packets to be routed across the network like common IP packets. This frees VMs on the Layer 2 network from the structural limitations of the Layer 2 and Layer 3 networks.

What is IPsec? How doe IPsec work?
Internet Protocol Security (IPsec) is a suite of protocols and services that provide security for IP networks. It is a widely used virtual private network (VPN) technology. IP packets lack effective security mechanisms and may be forged, stolen, or tampered with when being transmitted on a public network, such as the Internet. To solve this problem, the communicating parties establish an IPsec tunnel for encrypted transmission of IP packets. This ensures secure transmission of IP packets on an insecure network, such as the Internet.
What is NFV, how are NFV and SDN different?
NFV
Network functions virtualization (NFV) is a network architecture concept. Traditional network devices, such as routers, switches, firewalls, and load balancers, have their own hardware and software systems. Different from traditional devices, x86-based servers provide network functions after corresponding operating systems and software are installed. NFV uses the same architecture as that of x86-based servers. It decouples network functions from hardware, and instantiates them as independent software to run on general-purpose hardware.
What Is Edge Computing IoT?
IoT is developing rapidly and advancing towards the Internet of Everything (IoE). In the fully connected era, the surge in the number of device connections and amount of IoT data has spurred the development of edge computing technology. Edge Computing IoT innovatively brings the edge computing architecture to the IoT field, and provides data processing, storage, and application at the edge close to things. It addresses the "last mile" issue of IoT communication and implements smart connection and efficient management of IoT devices.
What Is Cloud Managed Network? Why Cloud-based Network Management?
A cloud managed network is a network that is managed from the cloud. It represents an innovative network management mode that utilizes the cloud management platform to manage and monitor network devices and service experience based on emerging technologies such as big data, artificial intelligence, and cloud computing. Huawei Cloud Managed Network Solution is implemented based on the CloudCampus cloud management platform on the Huawei public cloud. With this solution, cloud managed devices such as APs, switches, routers, and firewalls are managed on the cloud, allowing for fast deployment and centralized management of networks for Small and Medium-Sized Businesses (SMBs) and multi-branch organizations. The entire lifecycle of the network can be managed on the cloud, encompassing procurement, planning, provisioning, deployment, maintenance, and operation phases.
