News transmission system and its news buffering device and method

Abstract

The present invention discloses a message buffer unit used for realizing message buffer between transmitting side and receiving side. It contains message buffer; used for storing transmitting side data transmitted to receiving side; receiving side notifying unit used for message buffer transmitting signal to receiving side after receiving data, and notifying the receiving side to receive the data; buffer space detecting unit used for detecting buffer zone occupied space; transmitting side speed control unit used for according to space occupied status to regulate transmitting side speed. The present invention also discloses message transmission system adopting said message buffer unit and message buffer method.

Description

technical field [0001] The invention relates to a message buffering technology in a network communication process, in particular to a message transmission system and its buffering device and method. Background technique [0002] With the development of information technology, more and more information is transmitted through the network. see figure 1 , is a schematic diagram of sending and receiving messages between the first device 100 and the second device 200 through the network in the prior art. [0003] When the local program of the first device 100 sends a message to the second device 200, considering that the network communication is relatively slow, it is usually completed by a separate process or thread, that is, the network transceiver (process) process 120, for reasons of ease of management. The communication between networks, and the local processing line (process) process 110 communicates with the network sending and receiving line (process) process 120 in a ce...

Problems solved by technology

[0010] However, when the speed of the sender 310 is greater than the speed of the receiver 320, there is a certain problem in this notification method: the buffer 140 will be affected by the receiver 320 The speed is not fast enough and gradually becomes full, which eventually leads to the loss of messages; although setting a large enough buffer can play a certain role in relieving, but if the speed of the sender 310 is always faster than the speed of the receiver 320, no matter how large the buffer is, The buffer is of no help; and the size of the buffer 140 is difficult to set, if it is too large, it will waste space, if it is too small, the effect of message buffering cannot be achieved well

[0013] But, there are some weak points in the flow control method of this prior art:

[0015]2. The efficiency is not high enough

[0016]3. It is difficult to set the timeout period for the sender to wait

Since the receiver may indeed be out of work for some reason, causing the buffer to be full, the sender has no basis for judgment and can only wait for the longest timeout period
