Switched network system structure with adjustable throughput rate

Abstract

The invention discloses a switched network system structure with adjustable throughput rate, which aims at providing an expandable switched network system structure, so the throughput rate is adjustable, and the reliability, the flexibility and the controllability of the network can be improved. The invention adopts the technical scheme that: the switched network system structure with adjustable throughput rate is an improved tertiary-level indirect connection network system structure which has a complete switched capacity mode and a binary switched capacity mode, a first level of the complete switched capacity mode is formed by 2*3 crossbar switches with the quantity of P, a second level is formed by 4 Q*Q (Q=3P / 4) crossbar switches, and a third level is formed by 3*2 crossbar switches with the quantity of P. Each line card is provided with one 3*2 crossbar switch and one 3*2crossbar switch, the Q*Q crossbar switches of the second level is arranged on a core switching board of a router, and the core switching board is connected with the line card through a back panel; and when only the part field with even number or odd number is configured, the binary switched capacity mode is adopted. The structure of the switched network is simplified, the scale is easy to be adjusted, and the reliability of the data switch is improved.

Description

technical field [0001] The invention relates to the technical field of computer network routers, in particular to the high-speed switching network architecture in core routers. Background technique [0002] The high-speed switching network is an important part of the router. It connects the forwarding module and the interface module of the router, and switches the data packets from the input port of the router to the output port of the router. [0003] The rapid development of network traffic, scale structure, and upper-layer applications of the Internet puts forward higher and higher requirements on the performance, scale, and functions of routers, which leads to the continuous shortening of the life cycle of routers and the need to continuously upgrade routers. To upgrade a router, it must first expand its switching network, which makes the scalability of the switching network, that is, the ability to expand the network capacity and the number of ports while maintaining th...

Problems solved by technology

Compared with the direct connection network architecture, the throughput rate of the indirect connection network architecture can be well guaranteed; however, the throughput rate of the indirect connection network architecture is difficult to flexibly adjust according to the application requirements, such as the three-level Clos network, its throughput adjustment Limited by the number of ports of the intermediate-level switching unit, to convert a 4*4 three-level Clos network to a 6*6 Clos network, the intermediate-level switching unit must be at least a 3*3 switching unit, otherwise the existing switching cannot be used Network components, and the number of intermediate switching units required is difficult to control

Therefore, although the throughput rate of the directly connected network architecture has good adjustability, the overall performance of the network cannot be guaranteed, while the indirect connection architecture can provide good network performance, but the adjustability of the throughput rate is insufficient.
