Software & Key Features

1. SRv6 One‑Hop Cloud Access

   Native SRv6 BE and SRv6 Policy protocol stack realizes minute‑level service provisioning. Application‑aware and tenant‑aware intelligent path selection based on latency and bandwidth guarantees end‑to‑end SLA for branch‑to‑multi‑cloud traffic and simplifies cross‑domain network architecture.
2. Logical Network Slicing for Multi‑Service Isolation

   Supports sub‑interface‑based network slicing. Office, production and management services can share one physical device with strict logical traffic isolation, realizing flexible bandwidth adjustment to satisfy differentiated SLA requirements for government and industrial private‑network services.
3. Complete Routing, VPN and Multicast Protocol Suite

   Supports IPv4/IPv6 static route, RIP, OSPF, IS‑IS, BGP and BIERv6. Comprehensive multicast functions include IGMP, PIM‑SM/SSM. EVPN, L2VPN and L3VPN are supported for multi‑tenant service bearing; MPLS LDP, VLL/VPLS are available under MPLS mode.
4. Layer‑2 Feature Set

   VLAN, QinQ, Bridge Domain, STP/RSTP/MSTP, LACP link aggregation, G.8032 ERPS ring protection and transparent transmission of Layer‑2 control protocols.
5. Intelligent O&M Capabilities

   Centralized management supported via Huawei iMaster NCE controller. Supports Telemetry streaming telemetry and IFIT in‑band flow measurement under SRv6 mode for real‑time SLA visualization and fast fault location. Open YANG and RESTful APIs enable integration with third‑party orchestration platforms.
6. Built‑in Enterprise‑Grade Security

   Integrated ACL filtering, stateful firewall, IPsec VPN encryption, NAT and anti‑DDoS defense, providing comprehensive security protection for branch site and private‑network data transmission.

Typical Deployment Scenarios

• Medium‑scale enterprise branch and campus edge gateway
• Metropolitan access for government bureaus, township sites and financial branches
• Smart education, smart healthcare and smart factory private‑network access
• Multi‑service bearing scenarios requiring logical network slicing
• Remote sites requiring ZTP automatic deployment and branch‑to‑cloud interconnection
