Introduction

The IP network is evolving from pure data network (Internet) to telecom services bearer network. This transformation

has brought about significant challenges to the existing networking equipment and technologies.

Firstly, the core network equipment is being expected to offer more and more revenue-generating services through

smooth upgrading, and the Network Processor (NP) technology is accordingly introduced. While a traditional

ASIC-based core router normally features high performance with low cost, the lack of service flexibility presents a

big problem, which means hardware upgrade is usually needed and necessary for the router to offer new services.

However, with a NP-based router, new services can be easily implemented by software upgrade rather than hardware

upgrade. In short, while the NP technology combines the advantages of CPU and ASIC, the NP-based router features

high service flexibility without performance degradation.

Secondly, for the purpose of delivering carrier class services over the network, a variety of enhanced and new High

Availability (HA) technologies have been introduced.

Thirdly, the network architecture has been evolving towards a simpler and flatter hierarchy, which is putting more and

more requirements on the core network equipment: a single device is expected to provide both P and PE functions,

high density Ethernet Interfaces, layer 2 bridging functions, comprehensive service capability, etc.

As a manufacturer of telecom and Internet equipment, Huawei has abundant R&D and maintenance experience in

both PSTN and Internet. For recent years, by integrating its many years experience in the Internet and traditional tele-

com domains, Huawei has been concentrating on the development of telecom-specific IP bearer network and devel-

oped the NetEngine series core routers. By the end of June, 2008, there are over 45,620 sets of NE routers running in

the global IP networks, serving more than 112 NGN/Wireless bearer networks.

The Quidway® NetEngine 80E/40E Terabit Switching Router (TSR) is oriented towards the IP/MPLS backbone, IP bearer

network and other large scale IP/MPLS networks. As a NP-based core router, it adopts distributed forwarding archi-

tecture and non-block switching fabric, featuring carrier class reliability, wire speed forwarding performance, excellent

scalability and strong service capability. It supports 10G/20G flexible plug-in cards which can provide flexibility to meet

different requirements and reduce OpEx. It is also the industry’s first core router with built-in layer 2 bridging function

and high port-density Ethernet interfaces, making it very suitable for constructing Wireless/NGN IP bearer networks.

With NP powered packet forwarding engine, the NE80E/40E can offer new services just by software upgrade.



2 Quidway® NetEngine 80E/40E Core RouterSystem Overview

System Structure

The NE80E/40E adopts distributed forwarding architecture. The whole system can be divided into three logical planes:

data forwarding plane, control and management plane, and monitoring plane. The key point is that: control and for-

warding are separated; routing and switching are separated. In the aspect of reliability, all the key components adopt

redundancy design, and the system can provide carrier class reliability without single point failure.

The data forwarding plane is responsible for high speed processing and non-blocking switching of data packets. It •

encapsulates/de-encapsulates packets, completes IP/MPLS forwarding processing, QoS processing, and high-speed

switching. It also conducts various statistics.

The control and management plane serves as the nerve system. It is responsible for the processing of protocols and •

signaling. It is also responsible for the configuration, maintenance, report and control of the system status.

The monitoring plane is responsible for the monitoring and control over the operating environment. It performs •

tasks like voltage detection, fan speed adjustment, system powering on/off, fault isolation, fault alarming, etc.

NP Technology

With its NetEngine series core routers -- the well-known 5th generation routers, Huawei is the first vendor in the indus-

try who applies the NP technology in the router implementation.

Figure 3 gives a glance at what a Network Processor looks like. With dozens of forwarding micro-engines, hardware

co-processors and hardware accelerators, the Network Processor can provide functional flexibility along with high per-

formance. Just by upgrading the micro code, the NP-based router can provide desirable new services.

TSR with Built-in Bridging Functions

Huawei is the only vendor in the industry who can provide the TSR platform that integrated routing and layer 2 bridg-

ing functions, along with high-density and low-cost Ethernet ports, thus greatly reducing CapEx and OpEx, simplifying

the access of Wireless/NGN, and enhancing the network reliability.

For the traditional access solution of Wireless/NGN, the layer 2 switch has to be adopted between the TSR and the

MGW/SoftSwitch, providing the MAC/VLAN forwarding for VRRP and the traffic convergence (compared with layer 2

switch, the port cost of TSR is expensive).

However, it is most likely that the layer 2 switch tends to be a failure-prone point, rather than a kind of equipment

with carrier class reliability. With the layer 2 switch, the network structure becomes more complex, resulting in lower

reliability and higher CapEx and OpEx. The failure of the layer 2 switch would cause long-time service interruption,

which is normally about several seconds due to the convergence of MP-BGP and the relocation of Next-Hop PE.

As shown in Figure 5, with the layer 2 features and high-density and low-cost Ethernet ports, Huawei NE80E/40E TSR

can access the Wireless/NGN system directly, and the layer 2 switch can be taken away. This solution can simplify the

network structure, improve the reliability and reduce both CapEx and OpEx, as summarized in Table 2. It is worth stat-

ing that Huawei’s solution is generically applicable to multiple Wireless/NGN systems across various vendors.

In this application, the NE80E and NE40E serves as the core router or service POP, which can support triple play

services through abundant features such as DHCP/DHCP+, PIM-SSM, IGMPv3, PWE3, VPLS, H-QoS, MPLS OAM , RPR

and RRPP.

On the MAN, MAC-in-MAC is applied at the core layer, QinQ is applied at the access layer. Multiple services, such as

personal broadband access, VoIP/VOD, BTV, and interconnection of enterprises, are carried.

The MAC-in-MAC tunnel can be set up between the NE80E/40Es. It supports fault detection, fault location, and the

Automatic Protection Switching (APS). APS controls the protection switchover of the tunnel. The NE80E/40E supports

1+1 and 1:1 protection modes of the MAC tunnel. The NE80/E40E also supports the revertive mode, hold-off time,

and APS configuration mismatch test. This guarantees fast recovery of services.
