Problems solved by technology

[0006] 1. An end-to-end link detection mechanism is required to ensure the integrity of the link, but the implementation is complicated;
[0007] 2. Failure of a single link between frames will result in switchover of the receiving links of all service boards in the corresponding frame;
[0008] 3. Inter-chassis switching network plane cross failure will lead to the collapse of the entire system
[0011] 1. Failure of a single link between frames will lead to a coordinated switchover of the active / standby relationships of all frame SFUs;
[0012] 2. Inter-chassis switching network plane cross failure will lead to the collapse of the entire system;
[0013] 3. Special software and protocol management are required to switch between frames, which is not only cumbersome, but also takes a long time to switch

Embodiment Construction

[0043] The core of the present invention is that the switching network boards between the frames of the communication system are interconnected by a cross physical medium, and the service transmission mode of double transmission and double reception is adopted between the frames, so as to ensure the reliability of the service transmission between the frames in the communication system , and can reduce the complexity of system implementation.

[0044] The present invention firstly provides a system for inter-frame interconnection in a communication system, the structure of which is as follows image 3 shown, including:

[0045] Each frame of the communication system includes two switching network boards, usually the main switching network board and the standby switching network board. In the present invention, it is necessary to adopt cross physical media interconnection between the switching network boards between the frames; The use of crossover physical media interconnectio...

Abstract

The invention is concerned with the frame interlock system and the operation transmission method. Each exchange halftone of the frame interlocks by the overlapping physical medium in the communication system; when the operating boards between the frames needs to process the data transmission, sends the operation to each exchange halftone of the receiving frame by each exchange halftone in the sending frame; the operation board of the receiving frame need to receive the operation from each exchange frames respectively. The invention is using the overlapping physical medium to interlock each exchanging halftone between the frames of the communication system, using the both sending and both receiving operation transmitting mode between the frames, ensure the reliability of the frame operation transmission in the communication system, reduce the complex degree of the system achievement, in order to avoid the partial failure to affect the normal operation transmission of the whole network.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a system for inter-frame interconnection in a communication system and a service transmission method thereof. Background technique [0002] An existing communication system usually consists of multiple frames, and the multiple frames can be located in the same communication device or in different communication devices. Two SFUs are interconnected within a single frame, and the SFUs between frames are interconnected through a physical medium. The specific technical solution for inter-chassis interconnection is a problem that has been discussed in the industry. [0003] At present, there is an interconnection method between frames that adopts a star topology for interconnection between frames. The star topology interconnection refers to the interconnection between switching network planes between frames. The switching network plane 1, and there is no physical interc...
