Description
Technical field
The present invention relates to the communication technology, particularly many integrated circuit boards interpolation frame structural system.
Background technology
In data communication field,, generally all require the integrated circuit board of key is implemented redundancy backup in order to ensure the reliability of system equipment.The redundancy backup technology generally comprises the backup of 1:1, the backup of 1+1 and N:1 backup.The situation of 1:1 backup is to have only an integrated circuit board job simultaneously, after job card occurs unusually, then switches to backup card.1+1 backup is that job card and backup card are worked simultaneously, and job card outwards transmits identical data simultaneously with backup card when sending data, and system chooses the data of an integrated circuit board according to the operating state of current integrated circuit board when receiving data.The backup of N:1 is to use an integrated circuit board as the backup card that N opens integrated circuit board, when certain integrated circuit board breaks down, then its data is switched on the backup card.
1+1 backup is to implement the most succinct a kind of backup method, and it is broadcasted data at sending direction, and in the receive direction selective reception, having does not need the agreement support, only need determine the characteristics that RX path gets final product according to the local terminal state.For the 1+1 backup of integrated circuit board, usually require between job card and backup card, to make up the broadcast channel of special circuit, and need special circuit to handle the monitoring of integrated circuit board state as data, initiate switching of receive path between job card and the backup card etc.The shortcoming of doing like this one is the support that needs special hardware circuit, does not have good versatility; The 2nd, the state between the integrated circuit board is realized by both sides' active probe and negotiation, when explorer is made existing problem, may be caused working state of system unusual.
Summary of the invention
The present invention is directed to the redundancy backup method of prior art, technical sophistication, to the dependence height of hardware, the problem of integrated circuit board versatility difference proposes a kind of method that realizes the integrated circuit board 1+1 backup by software mode.
The present invention solve the technical problem, and the technical scheme of employing is that a kind of method of integrated circuit board redundancy backup may further comprise the steps:
A., integrated circuit board condition monitoring software module is set on the core control card, the integrated circuit board state is detected;
B. the core control card is according to the user configuration information and their operating state of running status setting of each integrated circuit board;
C. be set to the integrated circuit board of job card, when sending message, broadcast this message to its corresponding backup card simultaneously;
D. detect certain job card when unusual when the core control card, immediately backup card is switched to operating state, and this job card is switched to Status of Backups.
The invention has the beneficial effects as follows to have between the integrated circuit board of Gigabit EtherChannel, realize 1+1 backup, highly versatile; Whether integrated circuit board is in the redundancy backup state, only need just can determine by a user command, does not need to make up the support of special hardware circuit, has made full use of the existing hardware resource, has saved cost.
Description of drawings
Fig. 1 is a program flow diagram of the present invention.
Embodiment
Below in conjunction with embodiment, describe technical scheme of the present invention in detail.
The present invention is provided with integrated circuit board condition monitoring software module on the core control card of many integrated circuit boards interpolation frame structural system, be job card or backup card according to user configuration information and running status setting integrated circuit board.When software module detects certain job card when unusual, promptly send instruction to it, carry out state and switch.The present invention makes full use of the data exchange channel that had existed already between the integrated circuit board, finishes the communication of each integrated circuit board and the detection of running status, and the core control card carries out integrated circuit board and switches by operating state---the job card or the backup card of software instruction setting integrated circuit board.
Technical scheme of the present invention is that a kind of method of integrated circuit board redundancy backup may further comprise the steps:
A., integrated circuit board condition monitoring software module is set on the core control card, the integrated circuit board state is detected;
B. the core control card is according to the user configuration information and their operating state of running status setting of each integrated circuit board;
C. be set to the integrated circuit board of job card, when sending message, broadcast this message to its corresponding backup card simultaneously;
D. detect certain job card when unusual when the core control card, immediately backup card is switched to operating state, and this job card is switched to Status of Backups;
Concrete is: among the step a, described the integrated circuit board state is detected, be meant the state information of active detecting integrated circuit board running status and/or passive reception integrated circuit board report;
Among the step c, described message is meant broadcast data;
More particularly: steps d is, the core control card detects that the job card Link State changes and/or running status when unusual, immediately backup card is switched to operating state, and this job card is switched to Status of Backups;
Perhaps, when the core control card determines that in the keep-alive mode of network management communication job card quits work, immediately backup card is switched to operating state, and this job card is switched to Status of Backups;
Further be: in the described steps d,, also send warning information when the core control card detects job card when unusual;
Concrete communication mode is: communicate by the webmaster bus between core control card and job card and the backup card;
Carry out exchanges data by ether between job card and the backup card.
Embodiment
With the concrete application example of the present invention on MP9710, the realization of the 1+1 backup of ATM(Asynchronous Transfer Mode) interface card is described below:
MP9710 is the integrated service access system of the structure of integrated circuit board interpolation frame more than, and the atm interface card is one of interface integrated circuit board of MP9710, has Gigabit EtherChannel between each integrated circuit board of system.
At first, on MP9710 system core control card, integrated circuit board condition monitoring software module is set, establishes a communications link, according to the operating state of user configuration information and running status setting atm interface card by webmaster bus and atm interface card.If do not enable the 1+1 backup function of atm interface card, then every atm interface card can be by with Taihe county ply-yarn drill interaction data, network interworking, the business intercommunication of achieve frame relaying (FR) exchange or ATMFR and business such as converge.If activated the 1+1 backup function of interface integrated circuit board, then ply-yarn drill only passes through with Taihe county job card interaction data.Two atm interface cartoons are crossed the broadcasting that ether is finished data, and the ATM upper united mouth of job card and backup card outwards sends identical data simultaneously.When the core control card detects work atm interface card and integrated circuit board fault or physical link fault occur, then announce work atm interface card and switch the role, ply-yarn drill and backup atm interface cartoon are crossed the ether interaction data, the backup atm interface is stuck in when sending data, by ether data broadcasting is arrived former work atm interface card, simultaneously, core control card notice webmaster, send fault warning information, so that the attendant overhauls.Thus, be easy to just realize the 1+1 backup of atm interface card.Program flow diagram is referring to Fig. 1.
