1. 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:

Cluster Model Description
CCC-0 Consists of two CLCs.
The CLCs can be both NE5000E-16s, both NE5000E-X16s, both NE5000E-
X16As, or a combination of any two of them.
CCC-1 Consists of one CCC and a maximum of four CLCs.
The CLCs can be all NE5000E-16s, all NE5000E-X16s, all NE5000E-X16As,
or a combination of NE5000Es, NE5000E-X16s, and NE5000E-X16As.
CCC-2 Consists of two CCCs and a maximum of eight CLCs.
The CLCs can be all NE5000Es, all NE5000E-X16s, all NE5000E-X16As, or a
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
interfaces, and also support access control list (ACL)-based line rate forwarding.

5. 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
and high scalability
5

6.  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.

7. 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

device maintenance efficiency.
