Product Features

2.1 10G Performance and Terabit Capacity

The NE80E has taken an advanced hardware forwarding technology. A single NE80E chassis can support non-

blocking, full line-rate switching of up to 16 10G-interfaces, with a total interface capacity of 320G. The NE80E's

switching capacity reaches 640G, while the forwarding capacity 400Mpps, and the backplane capacity 4T.

2.2 Carrier-Class Architecture Design

The NE80E chassis adopts carrier class design with hot swappable boards. The chassis dimensions are 442 mm x

600 mm x 1600 mm (width x depth x height). It can be mounted in an N68-22 cabinet or a 19” standard cabinet. The

hardware structure of the NE80E has the following features in maintainability:

The backplane is installed from the rear of the chassis, which facilitates installation and maintenance.

There are two cable-management brackets respectively above and below the board cage, which facilitates the

cable layout and board installation and maintenance.

The fan modules can operate independently and support hot swap.

Two fan modules provide the function of heat dissipation for two board cages.

The NE80E provides a powerful monitoring system. The Main Processing Unit (MPU) implements the management

and maintenance for the whole system, including the boards, fans, Liquid Crystal Display (LCD) modules, and power

distribution modules, etc..

With module-level shielding performance and a steel sheet for each panel, the NE80E realizes the Electromagnetic

Compatibility (EMC) isolation between boards.

2.3 High Reliability

NE80E can meet the high reliability requirements for the carrier-class and high-end applications with the following

features.

Adopting hot swappable boards, power modules and fans.

Providing redundant key modules, such as: Main Processing Unit (MPU, 1+1), Switch Fabric Unit (SFU, 3+1),

power supply, fan modules, bus, and clocks.

Adopting the distributed hardware forwarding.

Separating the control channel from the service channel to provide a non-blocking control channel.

Possessing system/board fault detection, LEDs, and NMS alarm function.

Applying the generic integrated NMS platform which is independently developed by Huawei.

Supporting protection mechanisms such as IP/MPLS fast rerouting, interface automatic protection switching (APS/

MSP), Virtual Routing Redundancy Protocol (VRRP), RPR automatic protection switching.

2.4 Uncompromising IPv4 and IPv6 Compatibility

The NE80E fully supports IPv4 and IPv6 dual protocols stacks. It can provide all IPv6 features, and so offers a good

solution to smooth transition from IPv4 networks to IPv6 networks.

The NE80E supports three kinds of IPv6 over IPv4 tunnel techniques: manually configured tunnel, automatically

configured tunnel, and 6to4 tunnel. The large-capacity routing table and forwarding table enables the NE80E to

serve as the Virtual Private Network Provider Edge (VPN PE), and allows the future expansion of services.

The NE80E supports the distributed forwarding of both IPv4/IPv6 and Multi-Protocol Label Switching (MPLS). Due

to its powerful routing capability, the NE80E can be applied in the Internet backbone network. IPv4 supports the

routing table with a capacity of 3.2M routing entries, and IPv6 supports the routing table with a capacity of 2.6M

routing entries. The NE80E supports such IPv4 dynamic routing protocols as Routing Information Protocol (RIP),

Open Shortest Path First (OSPF), Intermediate System-Intermediate System (IS-IS), Border Gateway Protocol (BGP)

and multicast protocols. The NE80E supports such IPv6 dynamic routing protocols as BGP4+, RIPng, OSPFv3 and

IS-ISv6.

2.5 Excellent QoS Mechanism

The NE80E provides excellent QoS scheduling and buffer mechanisms, including:

PQ and Weighted Round Robin (WRR) / Weighted Fair Queuing (WFQ): guarantees the fair dispatching and

ensures that high-priority services are served first.

Three-stage switching network: is based on the Combined Input and Output Queuing (CIOQ) against Head of Line

(HOL) congestion.

Flow-based dispatching: facilitates MPLS TE and supports the Diff-Serv and Inter-Serv.

Hardware-based QoS functions: guarantees line-rate forwarding while providing QoS services.

The QoS mechanism can meet the requirements of the IP Telecom Network (IPTN). It can guarantee the delay, jitter,

bandwidth and packet drop ratio of different services. It also guarantees the launch of carrier-class services such as

the Voice over IP (VoIP).

2.6 Comprehensive Security Design

The distributed design of the NE80E isolates the data plane from the control plane. This design allows the NE80E to

offer industry-leading security features. With various security measures, the NE80E can prevent Denial-of-Service

(DoS) attacks, illegal accesses, and overload of the control plane, and offer data protection to ISP networks and

terminal users.

The NE80E offers the following security features:

Two user authentication modes: local authentication and RADIUS authentication

Applications

The NE80E is mainly used in the IP core/backbone network or as the convergence node. It can also act as the gateway in

the data center network with carrier class features. The NE80E provides multiple services such as the IPv4/IPv6 routing

and high-speed forwarding, MPLS, and IP multicast. In addition, it provides the MPLS TE to solve the traffic problem in the

backbone network. The applications include:

Core node application in the national/provincial backbone network

Point of Presence (PoP) application in the national/provincial backbone network

Core node application in the Metropolitan Area Network (MAN)

The NE80E has the following typical applications at present.

5.1 Application in the National Backbone Network

NAP: Network Access Point

Figure 5-1 Application in the national backbone network

As shown in Figure 5-1, the national backbone network is connected upstream to the international egress, and down-

stream to provincial backbone networks. It is also connected with other ISP networks through NAPs. The NE80E can work

as the core node of the national backbone network because of its large capacity, high-density ports, and powerful routing

and high-speed forwarding capability.

5.2 Application in the Provincial Backbone Network

Figure 5-2 Application in the provincial backbone network

As shown in Figure 5-2, the core layer of the provincial backbone network is composed of NE80E routers. The NE80/NE40

routers act as the city nodes to converge the traffic from the MAN, leased line convergence, narrowband access, and

Internet Data Center (IDC).

This solution is applicable to establishing, expanding or reconstructing large ISP provincial backbone networks. Usually,

these ISPs have access services and cost advantages, as well as transmission resources. In the case of transmission

resources shortage, the link bandwidth can be reduced accordingly without changing the network topology. The devices

on the convergence layer or above have the line rate forwarding capability. The entire network supports MPLS VPN.

5.3 Application in the IPv6 Backbone Network

PE: Provider Edge NAT-PT: Network Address Translation Protocol Translation

Figure 5-3 Application in the IPv6 backbone network

The IPv6 application in the backbone network should not impact on the original IPv4 services such as IPv4 forwarding and

MPLS VPN. So there are tow problems to be solved:

Interconnection between IPv6 islands

Interworking between IPv6 and IPv4 networks

The NE80E brings forward the following solutions based on IPv6 techniques:

All the routers in the backbone network support the IPv4/IPv6 dual-stack. In this case, IPv4 services are forwarded over

IPv4, while IPv6 services are forwarded over IPv6.

The interconnection between IPv6 islands can be implemented through L3 tunnels, manually configured tunnels or 6to4

tunnels. The core router needs only to support the IPv4 forwarding. The interworking between IPv6 and IPv4 networks

can be implemented by configuring the NAT-PT on gateways.

The interconnection between IPv6 islands can be implemented through MPLS L2 tunnels by applying MPLS L2 VPN

techniques such as VPLS and CCC. The core router needs only to support the MPLS forwarding. The interworking

between IPv6 and IPv4 networks can be implemented by configuring the NAT-PT on gateways.

In this application, the NE80E routers serve as the Providers (Ps) in the network core. For a multi-AS (Autonomous

System) VPN application, the NE80E can also act as a Customer Edge (CE) device when it is an Autonomous System

Boundary Router (ASBR). The NE80/40 routers serve as the Provider Edge (PE) devices, providing the NAT and the

Internet access.
