High-capacity non-jam route matrix

Abstract

The invention relates to a non-blocking route matrix, terminal modules with grouping functions are connected together through a plurality of CLOS switching planes, each terminal end and each CLOS switching plan only have a strip of connection, the input / output ends of the CLOS switching planes all adopt symmetrical switching units, and the number of middle grade switching units are equal to the number of outlet lines of the symmetrical switching unit of the input grade or the number of inlet lines of the symmetrical switching unit of the output grade. The route matrix chooses an input / output end to be a symmetrical switching unit, which reduces the number of crossing points, and lowers production cost, a stack-type route matrix is constructed, which can furthest connect more terminals, and meanwhile, connecting lines of each terminal are in an equal degree, which are mutually to be backup restore, capacity and reliability of systems are improved, exchange capacities with different sizes can be achieved through allocating the number of middle grade inlet / outline lines, when in upgrading, capacity of a system can be increased only through changing the capacity of the middle grade, and prophase investment is protected.

Description

technical field [0001] The invention relates to data communication, in particular to a large-capacity non-blocking routing matrix in a high-end router. Background technique [0002] With the rapid development of Internet technology, the IP bearer network is facing the convergence of various services such as data, voice, and video. Driven by new technologies and services, the traffic and scale of IP networks are expanding, and the performance of high-end routers in the future, such as system capacity and port speed, has become an urgent problem to be solved. [0003] At present, high-end routers mainly use a large-capacity matrix switching structure to achieve large system capacity. This switching structure takes the crossbar as the core and has a flexible topology configuration method. In theory, its capacity can grow infinitely with the increase of the number of ports. However, as the scale increases, this single-stage switching structure will inevitably increase the cost ...
