Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] The core idea of ​​the present invention is to directly set the level connection ports in the SFUs, and connect the SFUs of different chassis through the cascading channels connecting their respective level connection ports at both ends, so as to realize the connection of the system. Capacity expansion overcomes the disadvantages of increased system cost and heavy processing burden caused by capacity expansion through cascaded frames in the prior art. Moreover, while the present invention realizes system expansion based on the above-mentioned structure, two switching network boards that can perform active / standby switching each other are arranged in each machine frame, thereby ensuring the reliability of system operation.

Abstract

The invention discloses a grade-connecting system, which is characterized by the following: setting connecting hole in the swap screen plate directly; connecting itself grade-connecting interface and grade-connecting channel through two ends of swap screen plate of grade-connecting frame; setting two blocks of swap screen plates to proceed master switching mutually; reinforcing the accident self-healing ability of system; guaranteeing high-reliability of system operation. The invention also provides a sending control device of system, which realizes the identification of distributing control and master condition to control the received channel selectively.

Description

technical field [0001] The invention relates to the technical field of communication switching, in particular to a cascading system. Background technique [0002] In existing network communication devices such as switches and routers, multi-chassis cascading is usually used to expand the service capacity of the devices, that is, capacity expansion. However, traditional multi-chassis cascading is generally implemented by configuring cascading chassis or switching sub-modules attached to cascading single boards specially used to provide different cascading connection ports. Although the problem of system expansion can be solved, the cost and processing burden of the system are increased to a certain extent because the cascading frame is only used to provide cascading connection ports and has no switching function itself. Contents of the invention [0003] In view of this, the main purpose of the present invention is to provide a cascading system, which solves the problems o...
