The NetEngine40E series universal service router (NE40E) is a high-end network product provided by Huawei Technologies Co., Ltd. NE40Es are usually deployed at the edges of Enterprise networks, Campus Aggregation Network, IDC network and Interconnection networks between Enterprise Campuses. The NE20E, NE40E, and NE5000E together provide a complete, layered IP network solution.
The NE40E can be flexibly deployed at the edge or core of IP or MPLS networks, simplifying network structure. With its ability to provide an extensive range of services and reliable service quality, the NE40E is driving IP and MPLS bearer networks to develop greater broadband capacity and to become more secure, more intelligent, and more service oriented. Based on distributed hardware forwarding and non-blocking switching technologies of the CLOS distributed switching architecture, the NE40E features line-rate forwarding capability, a well designed Quality of Service (QoS) mechanism, strong service-processing capability, and excellent expansibility. The distributed QoS engine provides a packet buffer capability of 200 ms, which can solve the packet loss problem caused by burst traffic on the WAN network. The NE40E is based on a 400G platform and provides 100G line cards to satisfy the increased demand for bandwidth. NE40E has the ability to support virtualization; multiple devices can be virtualized into a single device. Compatible with all line cards currently in use, the NE40E minimizes investment needs.
The NE40E series, including NE40E-X16, NE40E-X8 and NE40E-X3, are suitable for networks of different scales.
Enhanced IPTV Service Functions
The NE40E has a built-in video caching, providing users with a smooth IPTV experience. Based on fast channel change (FCC), retransmission request (RET) and inline real-time stream monitoring, the NE40E can improve the user experience , optimize operations, administration and monitoring (OAM), save bandwidth resources, and reduce the total cost of ownership (TCO) of the entire network.
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 usercentered refined service operation.
Future-Oriented IPv6-Compatible Solutions
The NE40E supports a variety of IPv6 features including IPv6 leased line, NAT, dual stack, tunneling, and translation. The NE40E supports Next Hop Separation to optimize the IPv6 convergence time, supports larger IPv6 FIB and CGN card of 160G throughput to improve the scalability. All of them help to provide comprehensive solutions based on the high performance for transition from IPv4 to IPv6. And owing to the variety of technologies and different situations of provider networks, each provider will certainly select a conservative, reposeful, or aggressive transition technology that is the most suitable for its own network.
Providing reliability protection at different levels, including the equipment level, network level, and service level, the NE40E can cope with various kinds of bearer network failures and ensure service recovery. Based on these the NE40E provides a multi-level solution that can meet the requirements of the whole network and completely satisfy high reliability requirements. The NE40E acts as a foundation on which to build enterprise services with system availability at 99.999%.
Equipment-level reliability: The NE40E provides redundancy backup for key components. These components support hot swapping and hot backup. The NE40E also makes use of Non-Stop Routing (NSR), Non-Stop Forwarding (NSF), In-Service Software Upgrade (ISSU) and other technologies to improve services recovery and ensure uninterrupted service forwarding.
Network-level reliability: The NE40E supports IP/Label Distribution Protocol (LDP)/VPN/ TE Fast Reroute (FRR), hot-standby, fast convergence of Interior Gateway Protocols (IGPs), BGP and multicast routing, Virtual Router Redundancy Protocol (VRRP), Rapid Ring Protection Protocol (RRPP), trunk link backup, Bidirectional Forwarding Detection (BFD), MPLS/Ethernet Operation Administration, and Maintenance (OAM), and routing protocol/port/VLAN damping technologies to ensure the stability of the whole network. The NE40E provides an end- to- end network protection solution that can, in the event of a failure, guarantee service recovery within 200 ms.
Service-level reliability: The VPN FRR, E-VRRP, VLL FRR, Ethernet OAM, Y.1731, PW redundancy, E-Trunk, and E-Automatic Protection Switching (APS) technologies provided by the NE40E can be applied to L3VPN and L2VPN networking solutions. These provide service-level redundancies to ensure the stable and reliable delivery of services and to ensure continuous service forwarding.
Energy Saving Design
The environmentally friendly design of the NE40E saves energy and reduces emissions. The NE40E has an industry-leading cooling and energy-saving system which includes advanced ventilation and optimal heat dissipation design, intelligent fans, and a design for power supply distribution. By automatically sensing and adjusting temperature, the NE40E improves power supply utilization, making it an outstanding energy saver.
Enhanced Metro Ethernet Features
Based on Huawei’s mature Versatile Routing Platform (VRP), the NE40E excels in reliability, expansibility, and maintainability. The NE40E is an ideal platform for operators to build up carrier-class MANs. It supports various features to satisfy the requirement of carrying multi-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) server/replay/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 carrier-class MANs based on the NE40E, operators can provide Internet broadband access services, Internet Protocol Television (IPTV) services, family multi-play services, IP leased line services, enterprise interconnection services, and enterprise VPN services.
