Embodiment Construction

[0069] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0070] In the prior art, such as figure 2 As shown, the switching device generally includes: an input port, an input buffer, an in-queue scheduling module, an out-queue scheduling module, an output buffer, and an output port.

[0071] The input port is used to realize the conversion of the message to the data, and send the data to the input buffer;

[0072] The input buffer is used to store the incoming message from the input port, and send the message to th...

Abstract

The invention provides a message dequeue scheduling method and equipment thereof. According to the invention, the problem of packet loss caused by traffic burst can be solved. The method comprises the following steps: output rate which is cached by an output queue and is corresponding to the output queue is set as a first rate; whether data size in the output queue cache is greater than a preset value is judged; if the data size is greater than the preset value, the output rate cached by the output queue is set as a second rate which is greater than the first rate; and after a first preset time, the output rate cached by the output queue is set as the first rate. The method is suitable for the field of communication technology.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and device for dispatching messages out of queues Background technique [0002] The L2 layer 2 switching system usually implements queues by flow in the switching module. Each queue represents a flow. Each flow queue is configured with cache and bandwidth, and a flow queue-based scheduling is implemented internally. When scheduling according to the flow, the quality of service (English: Quality of Service, Qos for short) has good characteristics, which can solve the problem of input port head blocking. [0003] In the L2 switching system, a packet of any input port may be switched to any output port after passing through the L2 switching system. Such as figure 1 As shown, this L2 switching system has 4 input ports, port A, port B, port C, and port D, and has 4 output ports, port E, port F, port G, and port H. It so happens that at the same time, packets from inpu...
