Huawei's NE40E provides rich feature support and powerful service processing capabilities to meet the service needs of IP/MPLS bearer networks, MANs, and backbone networks.The NE40E has powerful routing capabilities, supports large routing tables, provides a rich set of routing protocols, such as RIP, OSPF, IS-IS, BGP4, and multicast routing, and supports plain/ciphertext authentication with fast convergence functions to ensure security and stability in complex routing environments. It guarantees security and stability in complex routing environments. Powerful service bearing capability, according to the network requirements can be simultaneously deployed L2VPN, L3VPN, MVPN, support and TE (Traffic Engineering) simultaneous deployment, support for flexible QinQ, support for DHCP/IPoE/PPPoE, but also provide GRE and other functions, to adapt to the traditional access needs and emerging business needs, to meet the rich bearer needs of multi-service convergence. Convergence of rich bearer requirements. Powerful scalable multicast capability, supports rich IPv4/IPv6 multicast protocols, including PIM-SM/SSM, MLDv1/v2, IGMPv3, IGMP Snooping, MLD Snooping and other features, which can flexibly carry IPTV and other video services, and meet the needs of multicast services of various scales.NE40E products have Perfect QoS scheduling mechanism: it supports five-level scheduling mechanism of H-QoS for the access side, which can diversify and differentiate to meet the service requirements of users at different levels on the access side; it supports MPLS H-QoS function for the network side, and supports the deployment of QoS function on the network side, which realizes the QoS capability of MPLS VPN, VLL and PWE3. The NE40E has good network resource allocation capability and provides a service quality solution for the whole network to meet the service requirements of customers with different priorities. Network-level reliability: NE40E provides IP/LDP/VPN/TE fast re-routing/hot-standby, IGP, BGP and multicast route fast convergence, VRRP (Virtual Router Redundancy Protocol), Trunk link sharing backup, BFD link fast detection, Ethernet OAM, routing and backup, and other features. The NE40E can provide end-to-end 200ms protection inversion with no service interruption by using the following technologies: VRRP, Virtual Router Redundancy Protocol (VRRP), Trunk Link Sharing Backup, BFD Link Fast Detection, Ethernet OAM, and Routing Protocol/Port/VLAN Damping. Service-level reliability: NE40E provides VPN FRR and E-VRRP technology, VLL FRR and Ethernet OAM technology, as well as PW Redundancy and E-Trunk technology, which can be applied to L3VPN and L2VPN networking solutions to ensure redundant backup at the service level, making the service stable, reliable and uninterrupted.
