Description
Technical field
The present invention relates to the communication technology, in particular, the present invention relates to a kind of route exchange device, IP network, communication system and path switching method.
Background technology
Present many networks all are based on the IP technology, how in IP network, to transmit wireless message and become the focus that industry is paid close attention to, because wireless message right and wrong IPization, for realize that wireless message transmits in IP network, usually can use frame exchange (Frame Relay, FR) technology, the typical networking that for example a kind of wireless message transmits in IP network as shown in Figure 1, message control unit (Packet Control Unit wherein, PCU) connect the base station, and carry out communication with the base station, PCU and wireless message management equipment, for example the service GPRS node (Serving GPRS Support Node, SGSN) message transmissions between the equipment need be carried by IP network, R1 router in the described IP network, R2 router and R3 router respectively with PCU, SGSN
A and SGSN B link to each other, described SGSN A is the main SGSN that uses, SGSN B then is standby SGSN, and is general, has only SGSN A in work, SGSN B is only at delay machine or just work in the path failure of SGSN A of SGSN A, be the active and standby usefulness in path of having used FR in the above-mentioned network, (Permanent Virtual Circuits PVC) carries out message transmissions to use the virtual path of primary path at ordinary times, when the PVC of primary path lost efficacy, use the PVC of backup path to transmit message.
Wherein R2INT2 is the interface that links to each other with SGSN A, R2INT1 is that the R2 router is used for and the establishment of R1 router transmits the interface of the path use of message, and R3INT2 is the interface that links to each other with SGSN B, and R3INT1 is that the R3 router is used for and the establishment of R1 router transmits the interface of the path use of message.The message that the R1 router transmits exchanges to primary path by FR and gets on, and by the IP backbone network message is sent in the R2 router, and the R2 router sends message to main SGSN (being SGSN A) and gets on according to configuration.
But in the above-mentioned communication system because SGSN A is a non-IP device, its can't pass through route assemblage, traffic engineering (Traffic Engineering, TE), the backup path of FR finishes the automatic switchover of transmission packet route.The switching that realizes the transmission packet route at present mainly is to adopt manual operations, for example the manual PVC that is mapped to primary path that makes lost efficacy on the R1 router, when PCU sends message to the R1 router, the R1 router transmits the PVC that message switches to backup path, send message to SGSN B by the R3 router then, but under the manual mode of operation of this kind technical scheme, the path of transmitting message is longer switching time, can cause the time of report lost literary composition long partially, maintenance cost is higher.
