Software & Key Features

1. SRv6 Intelligent Connectivity

   Adopts SRv6 protocol for native IPv6 support, implements one‑hop computing access, service provisioning within minutes. Supports application‑aware and tenant‑aware intelligent path selection based on latency and bandwidth to guarantee end‑to‑end SLA, simplifies network configuration with unified protocol stack.
2. FlexE Network Slicing

   Physical‑layer bandwidth isolation via FlexE technology. Multiple services run over the same physical infrastructure with strict traffic isolation, meeting differentiated SLA requirements for diverse computing and enterprise services.
3. Rich Routing & Multicast Capabilities

   Supports IPv4/IPv6 routing protocols including RIP, OSPF, IS‑IS, BGP, static routes, BIERv6. Comprehensive multicast functions: IGMP, PIM‑SM/SSM, MBGP, NG‑MVPN. Supports EVPN, L2VPN, L3VPN for multi‑tenant bearing.
4. Layer‑2 Functions

   G.8032 ERPS, STP/RSTP/MSTP, LACP, VLAN, QinQ, Bridge Domain, L2TPv3 and layer‑2 protocol transparent transmission.
5. O&M & Security

   Managed by Huawei iMaster NCE controller, supports Telemetry, IFIT in‑band flow measurement for real‑time SLA visualization. Provides ACL, firewall filtering, IPsec MACsec encryption, anti‑DDoS defense. Open YANG and RESTful APIs for third‑party integration.
6. Intelligent Computing‑oriented Enhancements

   Precise flow control to prevent fault spreading, adaptive flow‑level scheduling for network‑wide load balancing, high‑throughput optimization for wide‑area intelligent computing services华为企业业....
