Product characteristics

Extremely large capacity line card

The NE40E can support at maximum a 480G Line Card, which fulfills the increasing network requirements of customers. The powerful 480G line card can support both 100 GE and 10 GE port types, to provide customers with flexible configurations. With excellently developed chipset technology and fine design techniques, the NE40E provides sustainable high bandwidth capacity for the future.

Energy saving design

The NE40E uses Huawei-developed Solar chips, which are reliable and secure. It can dynamically allocate and manage multi-core NP resources and automatically disable redundant or unused ports, buses, and chips. The NE40E also supports dynamic frequency adjustment and intelligent fan speed adjustment, which significantly reduces power consumption, with less than 1W for each gigabit, the lowest in the industry.

Future-oriented IPv6-compatible solutions

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 NE40E 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.

Service-level reliability

The NE40E uses the following technologies to provide service-level reliability for L2VPNs and L3VPNs: VPN FRR, E-VRRP, VLL FRR, Ethernet OAM, Y.1731, PW redundancy, E-Trunk, and E-Automatic Protection Switching (APS) These technologies ensure stable and reliable service operation with no service interruption.

Enhanced metro ethernet features

Based on its mature Versatile Routing Platform (VRP), the NE40E excels in reliability, expansibility, and maintainability. It supports various features to satisfy the requirement to transmit multiple services, including Hierarchical Virtual Private LAN Service (HVPLS), Virtual Leased Line (VLL), Layer 2 VPN (L2VPN), Layer 3 VPN (L3VPN), multicast VPN, 802.1Q-in-802.1Q (QinQ), Virtual Local Area Network (VLAN) mapping, Dynamic Host Configuration Protocol (DHCP) relay/snooping, IPSec, NAT, and GRE. NE40E supports Protocol Independent Multicast-Source Specific Multicast (PIM-SSM), Internet Group Membership Protocol Version 3 (IGMPv3), and MAC + IP + VLAN user binding. On the high-reliability MANs based on the NE40E, ISP can provide Internet Protocol Television (IPTV) services, family multi-play services, IP leased line services, enterprise interconnection services, and enterprise VPN services.

In addition, the NE40E supports comprehensive Ethernet clock synchronization, which easily meets the requirements for IP networks used in electricity and transportation enterprise.

Enhanced User Management Functions

The NE40E provides Multi-Service Edge (MSE) features to manage and control DHCP/IP over Ethernet (IPoE)/leased line access users. The MSE mainly provides dynamic user access, user management, and user-based authentication, accounting, and QoS scheduling. In addition, the MSE implements Bandwidth-on-Demand (BoD) for different services of enterprise users and for DHCP individual users and changes the unified charging mode to the charging mode based on value-added services, which implements user-centered refined service operation.

Efficient OAM features

NE40E supports Ethernet OAM fault management including: Ethernet in the First Mile OAM (EFM OAM), conforming to IEEE 802.3ah and Connectivity Fault Management OAM (CFM OAM), and conforming to IEEE 802.1ag.

Conforming to ITU-T Y.1731, the NE40E supports performance management to measure the delay, jitter, and packet loss ratio when messages are transmitted. In this manner, the NE40E can detect the end-to-end performance of traffic in a specified time period and on a specified network segment.

Cooperating with performance management tools such as U2000, NE40E can provide SDH-like network OAM, service-oriented, intelligent warning, and refined positioning. By supporting efficient and precise performance measurement and test technologies such as IP FPM, TWAMP, RFC2544, and G.8032, the NE40E can help to simplify OAM and significantly save on OPEX. In addition, the ISP can monitor the network status in real time through the NMS — allowing the ISP to then check whether the forwarding capacity of the network complies with the Service Level Agreement (SLA) signed with users, and locate faults. The ISP does not need to carry out detection on the user side, which greatly decreases maintenance costs.
