Multiple frame trunking system and central exchanging frame and method capable of achieving data exchange

Abstract

The invention discloses a multiple frame trunking system, a central exchanging frame and a method capable of achieving data exchange, and belongs to the technical field of communication. The system comprises at least one user frame, external intersecting inter-working equipment and the central exchanging frame. The interior of the central exchanging frame comprises at least one exchanging net plate. The exchanging net plate in the central exchanging frame and the user frame are connected with the external intersecting inter-working equipment. User data of the user frame are intersected in the external intersecting inter-working equipment. The exchanging net plate in the central exchanging frame is used for conducting data exchange of the user data in the user frame through the external intersecting inter-working equipment. The exchanged data are sent to the user frame through the external intersecting inter-working equipment. The user frame and the central exchanging frame are connected through the external intersecting inter-working equipment so as to enable the exchanging net plate in the central exchanging frame to conduct the data exchange of the user data in the user frame through the external intersecting inter-working equipment, and therefore capacity of the trunking system is improved, realizing difficulty of the central exchanging frame is simplified, and system cost is reduced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a multi-frame cluster system, a central switch frame and a method for realizing data exchange. Background technique [0002] With the development of data communication technology, the data exchange capacity of a single data communication device can no longer meet the needs of users. In order to improve the exchange capacity of the system and meet the needs of users, a multi-chassis cluster system has emerged as the times require. A multi-chassis cluster system usually consists of a user chassis, a central switching chassis, and an inter-chassis interconnecting optical fiber. The user chassis is connected to the central switching chassis through the cascaded switching network board of the user chassis and the inter-chassis interconnecting optical fiber to realize data exchange. [0003] In the multi-frame trunking system provided by prior art 1, the central switching frame ...

AI Technical Summary

Problems solved by technology

[0005] Existing technology 1 realizes data exchange between the switching fabric boards in the central switching frame through the PCB backplane. The internal implementation of the central switching frame is complicated, and as the number of data links and the link rate increase, this solution is difficult to implement. At the same time, due to The photoelectric conversion module, the high-speed PCB backplane and the switching fabric board are all necessary components of the system, so the system cost is high; the second existing technology realizes data exchange between the switching fabric boards in the central switching frame through optical fiber cross-connection, and the optical fiber in the central switching frame Transition modules, optical fibers, and SFUs are all necessary components of the system, and the cost of optical fiber cross-connection is relatively high, so there is also the problem of high system costs
