Quidway® NetEngine 80E Core Router

Main Processing Unit

Overview

Main Processing Unit (MPU) is the core of the Quidway®NetEngine 80E core router (“NE80E”

hereinafter).

The NE80E provides 22 slots in total, two of which are reserved for the MPU. MPU supports hot

swapping. It is suggested that you configure two MPUs in order to implement MPU redundancy and

enhance the system reliability. Each MPU needs to be configured with one or two Compact Flash

(CF) cards (512MB) and memory (1GB). It is suggested to configure two CF cards and memory for

improving the system performance.

MPU is integrated with the clock module, LAN Switch module and CF card. As the core of system

control and management, MPU also serves as system clock source and maintenance and

management unit. It implements the functions of control and system maintenance planes.

The detailed functions are as follows:

zExecute routing protocols:

All routing protocol packets are sent by the forwarding engine to MPU for processing. The MPU

updates routing entries and load forwarding tables to the forwarding engine. In addition, the

MPU also is responsible to broadcast and filter routing packets and download routing policies

from the policy server.

zExecute the signaling protocols.

zProvide out-of-band channels for the communication between boards.

This function is attributed to the LAN Switch module and aimed to control, maintain and

exchange information between MPU, Switching Fabric Unit (SFU) and Line Processing Unit

(LPU).

zProvide level-3 clock and the reference clock of the switching network.

It provides service and interface boards with high-precision and high-reliability SDH clock

signals (38.388MHz). The clock module sends 2-channel 2.048MHz or 2.048Mbit/s

synchronization clock signals to lower-level equipment as it receives the 2.048MHz or

2.048Mbit/s clock reference.

zMonitor the running status of the system.

MPU collects the running data of units periodically and generates the control information,

including detecting whether boards are in position, controlling the running status of the

switching network and speeding up fans.

zManage and maintain equipment.

zConfigure data:

MPU is a storage place for system configuration data, boot files, billing information, upgraded

software and system running logs. Providing an interface for the CF card, MPU also functions

as a storage device to store data files.

zEnsure reliability:

MPU works in the 1+1 backup mode. Active and standby MPUs monitor each other. The

standby MPU takes over services when the active one gets faulty. MPU, clock module and LAN

Switch module are all designed with 1+1 hot backup, which enhances the system reliability.

Specifications

Currently the NE80E provides one type of MPU: CR52-MPUA. CR52-MPUA provides multiple

external interfaces whose specification and functions are described in the table below.
