Embodiment Construction

[0029] The implementation of the present application will be described in detail below with reference to the accompanying drawings and examples, so as to fully understand and implement the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects.

[0030] A new type of strictly non-blocking switching network, such as figure 1 As shown, it is a 4Nx4N switching network, including a main switching module and an end switching module. The main switch module includes 8 NxN central switch modules, and N must be a multiple of 4; the end switch module includes two 2Nx2N switch modules, and N must be a multiple of 4. The 8 NxN central switching modules are arranged in two columns and four rows in the connection relationship of the switching network. The NxN central switching module means that the central switching module is provided with N incoming channels and N outgoing channels, and the 2Nx2N switching modu...

Abstract

A new type of strict non-blocking switching network, including 8 NxN central switching modules and 2 2Nx2N switching modules; said N is a multiple of 4; in terms of connection relationship, said 8 NxN central switching modules are located in the middle, said Two switching modules are arranged on both sides, and the two switching modules are respectively connected to the central switching module; the central switching modules are connected to each other. The beneficial effect of the present application is that the switching structure is simplified, the number and difficulty of cascading wiring are reduced, the hardware cost is reduced, and the flexibility of routing selection during switching is improved.

Description

technical field [0001] The application belongs to the technical field of data exchange network, in particular, it relates to a novel strictly non-blocking exchange network. Background technique [0002] With the rapid development of communication technology, data exchange is widely used. In some scenarios, traditional switching technologies, such as crossbar and clos networks, restrict people's choices due to their large switching structure, complicated cascading wiring, and high hardware costs. [0003] For example: the traditional three-tier CLOS network is a three-tier switching network, such as Figure 10 As shown, the first layer is composed of r nxm, called the input layer; the second layer is composed of m rxr, called the middle layer; the third layer is composed of r mxn, called the output layer. There is one and only one link between each input layer switching unit and each intermediate layer switching unit, and one and only one link is connected between each inter...
