Abstract
The invention discloses a control method and device of a physical signal during router network access. The method comprises the following steps that: a router prohibits transmitting a physical signal after a physical interface is powered on; and the router transmits the physical signal by the physical interface after initialization is finished, and static data configuration restores to be successful. Through the technical scheme provided by the invention, the problem that UP can cause flow interruption when the router is not completely restored to be normal of the physical interface of the router in the prior art is solved, and furthermore, the effect of improving network reliability is achieved.
Description
Technical field
The present invention relates to the communications field, the control method and the device of physical signalling when a kind of router networks.
Background technology
Along with networks development, the user has proposed increasingly high requirement for the reliability of network, and people have expected the backup architecture based on equipment naturally, just as in server, adopting two hard disk structures for improving safety of data.Router is whole server and heart, if fatefulue fault takes place router, will cause the paralysis of local network, if P, the scope of influence will be bigger, and the loss that is caused also is difficult to estimate.Therefore, router being adopted the device level redundancy backup is the inevitable choice that improves network reliability.Under a complete inoperable situation of router, its repertoire is just taken over by another backup router in the system fully, recovers normal until the router that goes wrong.
The reason of fault has multiple, as because the router failure that software or hardware fault cause or restart, and active and standby switching that perhaps causes through configuration order during software upgrading or the like.
It should can operate as normal be criterion to switch the back router normally that router recovers, if router does not recover just often to switch just might cause flow interrupt as yet fully, network is produced immeasurable influence.
Not only there is dynamic data in router, more has a large amount of static configuration data.Can the use agreement message interaction between the router detect the neighbor router state, also can rely on interface UP (promptly can normally receive and dispatch physical signalling) simply, DOWN (promptly cannot receive and dispatch physical signalling) judges whether neighbor router is available.
In distributed router system, be divided into MP (Manage Processor according to function; Management processor), RP (Routing Processor; Protocol processor), NP (Network Processor, network processing unit), wherein MP mainly accomplishes functions such as command interpretation, webmaster; RP mainly realizes agreement, and NP mainly accomplishes protocol massages transmitting-receiving and data message forwarding etc.For integrated system, MP, RP, NP realize on a CPU, are mainly used in low side devices.For distributed system, MP, RP, NP are put into separately on the independent CPUs, are mainly used in high-end devices.In order to improve message forwarding performance, increase stability and reliability that message is transmitted, NP also can be put into a plurality of CPU and go up realization.
Concerning distributed system; In the router restarting process; The physical interface UP of NP tends to accomplish prior to the NP initialization; Thereby be issued to NP prior to configuration information from MP or RP, the physical interface of UP will be set up being connected physically smoothly with the neighbor router in the existing network, only relies on physical interface UP if neighbor router does not rely on protocol interaction and just judges that the in fact disabled router in opposite end can use; Will cause switching to unprepared router and cause flow interrupt, network is produced immeasurable influence.In like manner, because the asynchronous sequence problem that issues of information causes the INFORMATION OF INCOMPLETE on the NP also can produce immeasurable influence to network.
In sum, if the router physical interface does not recover might cause flow interrupt just often with regard to UP at router as yet fully, influence the reliability of network.
Summary of the invention
Recover UP just often to router physical interface in the prior art as yet fully at router, can cause the problem of flow interrupt, the control method and the device of physical signalling when the invention provides a kind of router and networking are to address the above problem at least.
