Embodiment Construction

[0045] 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 with reference to the accompanying drawings and examples.

[0046] Figure 7 Shown is a schematic structural diagram of a three-level CLOS according to an embodiment of the present invention. The switching system is composed of 128 input modules (FIP), 36 intermediate switching modules (FM) and 128 output modules (FOP). The middle switching module includes 128 input ports and 128 output ports, that is, a 128*128 switching structure. It should be further pointed out that the above switching structure is only a preferred embodiment of the present invention. In practical applications, the number of input modules, intermediate switching modules and output modules can be changed according to the actual situation. Such changes also belong to the present invention. protection scope of the invention.

Abstract

The invention relates to a multi-business supporting network switching device and an implementation method therefor. The device employs a multi-level CLOS switching configuration, and an input unit, an output unit and a switching unit are respectively provided with a buffer memory. The device can process a multi-business flow, and can achieve switching according to the business characteristics. The device can generate quick flow control in a congestion scene through the output unit, wherein the quick flow control acts on an input end, thereby reducing the congestion stress on the output end, and reducing the congestion degree of a central level. The device can reduce the input flow of a fault plane in a link fault scene through a load balancing scheme, and alleviates the congestion of the switching unit. An output unit package ordering method is employed, thereby reducing the design complexity of the switching unit. A data package cell load balancing method of the input unit is employed for enabling the time difference among cells to be small, thereby reducing the time delay of a data package, and reducing the size of the ordering and recombination buffer memory of an output end.

Description

technical field [0001] The invention belongs to the field of network switching devices, and in particular relates to a method for flow control and flow scheduling, intra-packet flow balance, and packet reorganization and sorting in the network. Background technique [0002] With the explosive growth of network traffic, the demand for the forwarding capability and scale of the switching system is also increasing sharply, which drives the rapid development of modern switching technology. An excellent switching architecture requires higher performance, high scalability, and high reliability. performance and good economical practicability. [0003] At present, the multi-level switching network topology can meet the performance and scalability requirements of the switching structure, and the effective bandwidth can be increased by using multi-plane high-speed parallel processing to meet the higher data processing rate. The composition of the most commonly used three-level CLOS s...
