Embodiment Construction

[0037] For a multi-level multi-plane switching system composed of a multi-level switching structure, when a link failure occurs inside the switching plane, the processing capability of the switching plane will also change accordingly. Aiming at this situation, a method is proposed to make the input unit adjust the sending traffic of its output port according to the failure of the link, so as to reduce the probability of congestion in the switching plane where the failed link is located.

[0038] Such as figure 1 As shown in FIG. 2 , it is a schematic structural diagram of a three-stage switching system applying an embodiment of the present invention.

[0039] The three-level switching system in the embodiment of the present invention includes: an input-level module IM (input unit), a middle-level module CM (switching plane) and an output-level module OM (output unit) to form a three-level switching structure.

[0040] Each intermediate module CM(i) can be regarded as a switch...

Abstract

The inventive embodiment discloses a data stream method, system and device for multilevel multi-planar construction. The method includes the following steps: determining an available output terminal port according to the destination address of data stream; judging whether the failure identification exists in the first marker field and/or the second marker field corresponding to the output terminal port; when the failure identification exists in the first marker field and/or the second marker field corresponding to the output terminal port, regulating the data stream flow quantity of the output terminal port according to the failure identification. The invention can regulate the transmitting flow quantity of the output terminal port according to the fault instance of chain circuit, and reach the effect of reducing the probability of congestion occurrence in the exchanging plane of the fault chain circuit.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and system for sending data streams in a multi-level and multi-plane structure. Background technique [0002] At present, the switching structure of high-performance routers generally adopts a multi-level and multi-plane structure. This structure has the characteristics of easy expansion and self-routing, and can provide a large switching capacity and strong fault tolerance. [0003] A typical three-level switching system (Cross switching system) is mainly composed of the following parts: input-level modules, intermediate-level modules and output-level modules form a three-level switching structure. Each of the intermediate-level modules can be regarded as a switching plane, which is actually a three-level switching structure, which consists of the following three parts: the first-level switching unit module, the second-level switching unit module,...
