Overview
The
NE40E supports a variety of IPv6 features including IPv6 leased line, dual stack, tunneling, and translation. The NE40E supports Next-Hop Separation to optimize the IPv6 convergence time and supports larger IPv6 FIB and CGN cards of 160G throughput to improve the scalability. These help to provide comprehensive solutions for high performance in transition from IPv6 to IPv4 and allow each provider to determine their transition strategy most suitable for their own network.
All-round reliability solution
The NE40E provides reliability protection at different levels, including the equipment, network, and service levels. The NE40E can provide a multi-level reliability solution that completely meets the reliability requirements of different services. The NE40E lays the foundation for enterprise services with a system availability of 99.999%.
The following describes the reliability protection levels that the NE40E provides:
Equipment-level reliability
The
Huawei Router NE40E-X3 provides redundancy backup for key components. These key components support hot swapping and hot backup. The NE40E also uses technologies, such as Non-Stop Routing (NSR), Non-Stop Forwarding (NSF), and In-Service Software Upgrade (ISSU), to ensure uninterrupted service forwarding. The NE40E supports packet buffering of 200 ms, ensuring no packet loss in the case of traffic bursts — guaranteeing high-quality service experience for users.
Network-level reliability
The NE40E uses the following technologies to provide network-level reliability: IP Fast Reroute (FRR), Label Distribution Protocol (LDP) FRR, VPN FRR, TE FRR, hot standby, fast convergence of Interior Gateway Protocols (IGP), BGP, and multicast routes, Virtual Router Redundancy Protocol (VRRP), Rapid Ring Protection Protocol (RRPP), trunk load balancing and backup, hardware-based Bi-directional Forwarding Detection (BFD) of 3.3 ms, MPLS OAM, Ethernet OAM, and routing protocol/port/VLAN damping. The NE40E provides an end-to-end protection with no service interruption.
