Huawei NetEngine5000E Core Router

Chassis and Features

The Huawei NE5000E (NetEngine5000E Core Router), one type of Huawei router, which has large capacity and high performance, is developed to meet the requirement of carrier-class reliability. Based on the powerful versatile routing platform (VRP), the NE5000E provides strong switching capabilities, dense ports, and high reliability. NE5000Es mainly serve as super-core nodes on carriers' backbone networks, core nodes on metropolitan area networks (MANs), egresses in large-scale Internet data centers (IDCs), or core nodes on large-scale enterprise networks.

NE5000E clusters are positioned as super-core nodes on backbone networks, supporting Layer 3 routing and Multiprotocol Label Switching (MPLS) forwarding. In an NE5000E cluster, a cluster central chassis (CCC) functions as a level-2 switching module and routing engine module in a three-stage switch fabric; a cluster line-card chassis (CLC) functions as a level-1 or level-3 switching module and forwarding module.

V800R005C01 supports the following types of chassis:

combination of NE5000Es, NE5000E-X16s, and NE5000E-X16As.

Powerful Forwarding Capability

Designed with a hardware-based forwarding engine, NE5000E series routers support full-duplex forwarding of IPv4, IPv6, and MPLS packets at the line rate on all

4

interfaces, and also support access control list (ACL)-based line rate forwarding.NE5000E series routers support multicast traffic forwarding at the line rate. The hardware of NE5000E series routers supports two-level multicast traffic replication: replication from switch fabric units (SFUs) to LPUs and replication from the forwarding engine of an LPU to associated interfaces.An LPU can buffer packets, ensuring that no packet is lost in the case of traffic burst.

Well-Designed QoS Mechanism

NE5000E series routers provide the following QoS functions: Rule-based traffic classification: Traffic can be classified based on Layer 2 rules,

Layer 3 rules, and MPLS rules. Differentiated services: Differentiated services are provided for traffic with

different differentiated services code point (DSCP) values, EXP values, 802.1p priorities, or IP precedence.

Traffic marking: The DSCP values, EXP values, 802.1p priorities, or IP precedence of specific traffic can be modified based on a pre-defined policy.

Traffic policing: All traffic or specific traffic on a specified interface can be monitored for traffic limiting.

Congestion avoidance: Tail drop or weighted random early detection (WRED) is used to drop certain packets in a queue to prevent queue overflow.

Congestion management: Priority queuing (PQ) and weighted fair queuing (WFQ) are provided so that fair queue scheduling is ensured and services with a higher priority are processed preferentially.

These QoS functions ensure different delays, jitter, bandwidth, and packet loss ratios for different services, such as voice over IP (VoIP) and IPTV services, carried over an IP network.

Robust Security Design

NE5000E series routers provide multiple security features to protect the data of Internet service providers (ISPs) and users. These features can protect services against denial of service (DoS) attacks, authorized access, and traffic overload on the control plane. The NE5000E series routers use a distributed structure that separates the data plane from the control plane, providing industry-leading security performance.NE5000E series routers provide the following security features: Three user authentication modes: local authentication, Remote Authentication

Dial In User Service (RADIUS) authentication, and Huawei Terminal Access Controller Access Control System (HWTACACS) authentication

Hardware-based packet filtering and sampling, which ensures high performance 5

and high scalability Plain-text authentication and message digest algorithm 5 (MD5) authentication of

Open Shortest Path First (OSPF), Intermediate System to Intermediate System (IS-IS), Routing Information Protocol (RIP), and BGP-4 packets

Forwarding- or control-plane-based ACLs Unicast reverse path forwarding (URPF), which checks the source address

validity and drops invalid packets Generalized TTL Security Mechanism (GTSM) Traffic filtering based on the ACL carried in a BGP Flowspec route or the local

policy that the route attribute matches

Comprehensive IPv4/IPv6 Features

NE5000E series routers support the IPv4/IPv6 dual stack and provide comprehensive IPv6 features that smooth migration from IPv4 networks to IPv6 networks.NE5000E series routers support: Multiple types of IPv6 over IPv4 tunnels Large-capacity routing tables and forwarding tables, meeting the requirements of

VPN provider edges (PEs) and future service expansion Distributed forwarding of IPv4/IPv6 and MPLS packets

Excellent Scalability and Rollback Capability

NE5000E series routers have excellent scalability and rollback capability: An NE5000E single chassis can be smoothly expanded to a CCC-0, CCC-1, or

CCC-2 system. A CCC-0 system can be smoothly expanded to a CCC-1 or CCC-2 system. A CCC-1 system can be smoothly expanded to a CCC-2 system. An NE5000E cluster can be rolled back to an NE5000E single chassis.

Carrier-class Reliability and Manageability

NE5000E series routers offer carrier-class reliability and manageability. An NE5000E series router can be installed in an N68E cabinet or a standard 19-inch cabinet.NE5000E series routers also provide a powerful monitoring system. The main processing units (MPUs) manage, monitor, and maintain the boards, fan modules, and power modules of the entire system.NE5000E series routers comply with Electromagnetic Compatibility (EMC) standards. The modular design of the NE5000E series routers achieves EMC isolation between boards.

Flexible VS Functions

NE5000E series routers support virtual system (VS). VS is an important feature of new-generation IP bearer devices and plays an active role in centralized operation and capital expenditure (CAPEX) and operational expenditure (OPEX) reduction. Carriers can divide a large physical system (PS) into multiple smaller separate VSs, optimizing physical resource allocation and making networking more flexible.VS can: Reduce CAPEX and OPEX. Flatten networks. Support multi-service networks.

Different services are deployed on different VSs, forming a logical multi-service network. This isolates different types of services to improve security and reliability.

Verify new services.New services, such as IPv6 and video services, can be verified on VSs, which isolate services and have no impact on the existing network applications.

Ideal L2VPN Solution

NE5000E series routers support the MPLS L2VPN technology. MPLS L2VPN transparently transmits Layer 2 user data over an MPLS network. From a user's perspective, an MPLS network is a Layer 2 switching network on which Layer 2 connections can be set up between nodes. MPLS L2VPN can be classified as virtual private LAN service (VPLS) or virtual private wire service (VPWS). VPWS is a technology that transmits Layer 2 services by emulating basic behaviors and features of services such as Ethernet, synchronous optical network (SONET), and synchronous digital hierarchy (SDH) on a packet switched network (PSN). VPWS is a point-to-point L2VPN technology. A VPWS service enables two sites to communicate as if they were directly connected by a link. A VPWS service, however, cannot allow more than two sites to communicate.VPLS uses the PSN to connect multiple Ethernet LAN segments, enabling them to work as a single LAN. VPLS is also called transparent LAN service (TLS) or virtual private switched network service (VPSNS). Different from common point-to-point L2VPN services, VPLS enables a service provider to offer an Ethernet-based multipoint service to users over an MPLS backbone network.

Easy Rollback Configuration

NE5000E series routers provide the rollback function. Rollback is important for 7

configuration management as it can reduce the operation error ratio and improve device maintenance efficiency.
