Abstract
The invention relates to a redundant backup method based on a port, which includes the following processes: all ports of two interface boards are in an active state and at the same time receive data from a line port and respectively connects the processed data messages with master and slave data processing boards through a backplane bus; when a fault exists in a main port, a redundant control module of a main interface board transmits the fault state to the redundant control module of the master data processing board through a standby board; the redundant backup module of the master data processing board selects a standby port to switch. In the invention, the data processing board respectively caches the data messages in each main port and standby port to achieve rapid and smooth hardware switch; besides, only the ports with the fault are switched and the ports without the fault are not affected. When a fault exists in a port, the invention can rapidly, safely and reliably switch to the standby port to ensure the normal operation of communication; besides, fault information can be reported through network management timely; the invention has the advantages of simple design of the hardware and high working reliability.
Description
Technical field
The present invention relates to communication system, particularly based on the method for the redundancy backup of port.
Background technology
Along with networks development, the middle and high end router in communication network, switch, the network equipments such as media gateway all need to possess the functional reliability of long-time running.Crucial nucleus equipment provides the important means of its reliability when carrying out the redundancy backup design.Surplus standby system is divided into two kinds of cold standby and Hot Spares, because the switching time that cold standby needs is very long, can have influence on original path.The general Hot Spare technology that adopts.
The method that the present interfaces plate is switched based on the redundancy of port failure has two kinds:
(1) active and standby interface board switches: be exactly to have on the main interface plate after a port breaks down, switch to the interface board of backup, and report fault message by webmaster.Its advantage is that technology is simple, and cost is lower.Shortcoming is exactly: can have influence on other normal trouble-free ports by the main interface plate to the switching of spare interface board
(2) active and standby port switches: when a main port breaks down, need be by the support of software, and the untreated data of this port are backuped to the interface board that is equipped with of backup, switch to fully corresponding backup port on the interface board.Shortcoming is exactly: switching time is long, can not switch to smoothly on the standby port.
Summary of the invention
The purpose of this invention is to provide a kind of method of switching based on the interface board standby and main redundancy of port.
For achieving the above object, a kind of method of the redundancy backup based on port comprises:
The all of the port of two interface boards is in active state simultaneously, receive the data from line port, and the data message passage after will handling is received principal and subordinate's data processing plate by core bus separately;
After certain main port breaks down, the main redundant control module that malfunction is sent to the master data disposable plates by slave board with the redundant control module of interface board;
The redundant control module of master data disposable plates selects standby port to switch.
The present invention's method that to be the data processing plate carry out buffer memory respectively to the data message of each active and standby port reaches level and smooth fast hardware to be switched, and just switches out of order port, and trouble-free port is not affected.When arbitrary port breaks down, can be rapid, switch to safely and reliably on the standby port, guarantee normally carrying out of communication, and can in time report fault message that hardware designs is simple, the functional reliability height by webmaster.

Embodiment
As shown in Figure 1, comprise a master data disposable plates and one in the redundant system from the data processing plate, two interface boards, they are inserted into respectively on two adjacent slot positions of backboard, and the front of groove position is an interface board, and the back is the data processing plate.Wherein the function of data processing plate is carried out caching process and conversion to the data message exactly, and the function of interface board provides external interface and data message is passed to Main Processing Unit.
The all of the port of two interface boards is in active state simultaneously, receive the data from line port, and the data message passage after will handling sends to principal and subordinate's data processing plate by core bus separately.The data processing plate comprises N*2 buffer area, and the buffer area of N wherein is used for storing the data from N port of interface board 1, and N buffer area is used for the data of access from N port of interface board 2 in addition.
As shown in Figure 2, two data disposable plates are carried out main and standby competition after power-up initializing, and the redundant state according to mutual hardware and software determines the principal and subordinate.The master data disposable plates is selected the interface board of main usefulness and the port of main usefulness according to the state indication of interface board, and its data processing module just is in the main data message of using N buffer to ports district of state, and N buffer area just is in the stand-by state in addition.
After some main ports broke down, the redundant control module B of interface board can send to malfunction the redundant control module A of data processing plate by backboard.The processing procedure of redundant control module A is at first checked the state of the corresponding port of spare interface board as shown in Figure 3, if can switch, selects the data buffer area of standby port to handle with regard to the notification data processing module.If cannot switch, just notify webmaster.
Fig. 4 is this port redundancy control method realization on media gateway, and through test, when port broke down, this system can be rapid, switches to standby port smoothly.
