Embodiment Construction

[0025] In the process of data transmission, traffic shaping is a more commonly used method of controlling data flow. In this embodiment, the data source X described above is still used to generate large bursts, and the traffic shaping of the present invention will be described in detail with reference to the accompanying drawings. method.

[0026] In order to make it easier for the technicians to understand the method of the present invention, the following description will still take an ATM (Asynchronous Transfer Mode) network as an example. Let’s take a look at the existing methods of traffic shaping, such as image 3 As shown, the data source X generates a larger packet burst, the burst length is N, the queue length is also N, the data stream is shaped by CBR (constant cell rate), and SCR (continuous cell rate) It is just 1 / 2 of the sending rate, that is, within 2T of every two message scheduling periods, a message of data source X can be sent out. The shaping part inserts the ...

Abstract

The invention discloses a flow shaping method in data transmission process, the method includes following steps: a) creates a storage structure for storing waiting message, each unit in the transmitting queue is correspondent to a storage structure; b) determines the unit which can buffer waiting message in the transmission queue, stores the message into the storage structure correspondent to the buffer unit; c) dispatches the preset message transmission in the storage structure according to the dispatching tactics. The invention has several storage structures and sets different transmission times in order to guarantee the transmission is correct, it can reduce the length of transmission queue greatly, reduces the occupation of inner memory.

Description

Technical field [0001] The invention relates to a method of data transmission, and more specifically to a method of flow control in the process of data transmission. Background technique [0002] Nowadays, data communication technology is developing rapidly, and a large amount of data is being transmitted in the communication network at all times. Therefore, handling the transmission of data in the communication network is an important means to improve the utilization rate of network resources and the efficiency of data transmission. With the transmission of a large amount of data on the network, this situation often occurs. Due to the limited network capacity, when a burst of data flows, a lot of data is often discarded before it is too late to be sent; sometimes in order to meet the quality of network service customized by users, It is necessary to control the transmission of data transmitted in the network, such as sending data according to specific time, rate, order, etc., an...
