Problems solved by technology

[0026] However, if routers 301, 302 are used to realize the working channel between RPR rings 310, 320, then when the working channel fails, the protection time of the working channel will depend on the protection time of the router, and the protection time of the router is all within Above the second level, it cannot meet the protection requirements of the carrier level, and the protection time of the carrier level is not greater than 50 milliseconds
Additionally, by image 3 The interconnection technology scheme shown cannot guarantee the service level CoS between the rings 310 and 320, because the router passes through the middle, and the router will replace the information of the data frame, so that the information using the separation level of the second layer cannot be transmitted to the in another loop

Embodiment Construction

[0063] Figure 4 is a schematic diagram of an RPR ring interconnection system according to an embodiment of the present invention. Figure 4 The illustrated RPR ring interconnection system includes two RPR rings, that is, RPR rings 410 and 420 . Wherein, the RPR ring 410 includes four stations 411 , 412 , 413 , and 414 ; the RPR ring 420 includes four stations 421 , 422 , 423 , and 424 . The RPR site can be a device with only the RPR function, or a switch, router, SDH and other devices with the RPR function.

[0064] It should be noted that although the Figure 4 The RPR ring interconnection system drawn in includes two RPR rings, but in fact, an RPR ring interconnection system can include more than two RPR rings, and can include multiple RPR rings, but at least two RPR rings can constitute a RPR ring interconnection system.

[0065] It should also be noted that although Figure 4 Only four sites are drawn on each RPR ring shown in , but those skilled in the art should un...

Abstract

The interconnection system at least comprises a first resilient packet ring and a second resilient packet ring. Said resilient packet rings at least comprise a working station and a standby station. The method thereof includes: establishing a working channel between the first working station of the first resilient packet ring and the second working station of the second resilient packet ring in order to make inter-ring transmission; establishing a standby channel between the first standby station of the first resilient packet ring and the second standby station of the second resilient ring; when a failure happening in the working station or working channel is detected, the standby station uses the standby channel to make inter-ring transmission service.

Description

technical field [0001] The present invention relates to the technical field of resilient packet ring (Resilient Package Ring-RPR), in particular to a method for realizing reliable cross-ring service transmission between at least two interconnected resilient packet rings and a method used in the interconnected system Cross ring site. Background technique [0002] RPR is a metropolitan area network technology that uses a dual-ring structure to transmit data between multiple sites. It has been approved by the IEEE (The Institute of Electrical and Electronics Engineers, The Institute of Electrical and Electronics Engineers) 802.17 working group standardization. The key features of RPR include the following: [0003] (1) Regardless of the transmission medium [0004] The transmission medium constituting RPR can be SDH (Synchronous digital hierarchy), SONET (Synchronous optical network), FDDI (Fiber Distributed Data Interface), or Gigabit (1GE or 10G), etc. Wait; [0005] (2)...
