Method for sending indirect real time traffic control data

Abstract

The invention relates to an indirect real-time flow rate control data transmission method, which adopts transmission index queue (21). The method comprises the following steps: a network application writes down the data into a spare data block in the transmission buffer and changes the spare data block into an occupied block and adds an index of the occupied block to the tail of a transmission index queue; a network protocol reads the unread data blocks pointed by the queue member according to the order of transmission index queue members, changes the unread data block into read data block, deletes the member from the transmission index queue after obtaining a successful transmission response and then changes the occupied data block into spare data block. The transmission method adopts transmission index queue to replace transmission buffer physical address and transmits data packets in order. With no increase in flow rate control information, real-time performance of data transmission in middle and lower layers of packet network is improved, and flow media transmission quality is effectively improved.

Description

technical field [0001] The invention relates to real-time flow control in network transmission, and more specifically relates to an indirect real-time flow control data sending method. Background technique [0002] In the circuit domain, packet switching domain, or other network forms, data is transmitted between network nodes in a single or group form. The same size is a frame, and the data block is a different size. Data is also copied between layers by software and hardware cooperation within the network layer. Flow control is generally the control of grouped data. The normal transmission of data can be guaranteed by adjusting the transmission speed. It is an important control factor in data transmission, but at the same time, it must take into account various real-time and synchronization requirements of the network and data. . [0003] The demand for flow control includes the situation that the demand is greater than the resource coordination of the supply; the proces...

Problems solved by technology

If the entire group of data blocks is copied to one area and then read, the real-time performance will be reduced, and at the same time, the delay limit of the business may not be met.

This problem is mainly due to the inconsistency in the size of mutually exclusive objects, which makes real-time performance difficult to achieve.
