Software & Key Features

1. SRv6 One‑Hop Cloud Access

   Native SRv6 BE and SRv6 Policy protocol stack delivers minute‑level service provisioning. Application‑aware and tenant‑aware intelligent path selection based on latency and bandwidth guarantees end‑to‑end SLA for industrial production and remote control services.
2. Network Slicing for Multi‑Service Converged Bearing

   Supports logical network slicing to realize multi‑network integration. Production control network, video surveillance, 5G bearer and power monitoring services run on shared physical infrastructure with strict traffic isolation, satisfying differentiated SLA requirements of industrial private networks.
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 bearing; MPLS LDP, VLL/VPLS 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 for industrial ring‑network deployment.
5. Intelligent O&M Capabilities

   Centralized management by Huawei iMaster NCE controller. Supports Telemetry streaming telemetry and IFIT in‑band flow measurement under SRv6 mode, achieving real‑time SLA visualization and fast fault localization for above‑ground and underground networks. Open YANG and RESTful APIs support third‑party orchestration integration.
6. Industrial‑Grade Integrated Security

   Built‑in ACL filtering, stateful firewall, IPsec & MACsec link encryption, NAT and anti‑DDoS defense, providing end‑to‑end security protection for industrial site production data transmission.

Typical Deployment Scenarios

• Underground and surface access gateway for smart mining private‑networks
• Edge access for energy, petroleum and chemical industrial parks
• Production control, video surveillance and 5G backhaul converged bearing
• Harsh‑environment sites requiring fan‑less wide‑temperature operation
• Remote industrial sites requiring ZTP automatic deployment and branch‑to‑cloud interconnection
