Embodiment Construction

[0051] Below in conjunction with accompanying drawing, structural principle and working principle of the present invention are specifically described:

[0052] see figure 1 , figure 1 It is a method flow chart of an embodiment of the present invention. The reputation-based link congestion control method of the present invention integrates congestion control and reputation flow control between each hop of the link, and adjusts the sender's sending rate through the receiver's reputation value to avoid link congestion. Including the following steps:

[0053] Step S100, the sender initializes the initial information maintained by itself, the initial information includes the sending count, the receiver's reputation value and the current sending window size;

[0054] Step S200, calculate and maintain the sending threshold, determine a sending threshold according to the receivable buffer quantity of the receiving party, and use the sending threshold as the basis for the sending part...

Abstract

Disclosed is a reputation-based link congestion control method, in which congestion control and reputation flow control are integrated between hops of a link and a transmission rate of a sender is adjusted through a reputation value of a receiver to avoid link congestion. The method comprises the steps of initializing initial information the sender maintains by the sender, the initial information including a transmission count, the reputation value of the receiver and a current transmission window size; calculating and maintaining transmission thresholds, determining a transmission threshold based on the number of receivable buffers of the receiver, and considering the transmission threshold as a basis for adjusting the transmission rate of the sender; and adjusting the transmission rate of the sender according to the transmission threshold, and automatically adjusting the transmission window size based on the transmission threshold to avoid packet loss due to a buffer overflow of the receiver.

Description

technical field [0001] The invention relates to the field of data transmission of network switches, in particular to a credit-based link congestion control method for network switches. Background technique [0002] In the current network, most of the data transmission should try to avoid the occurrence of congestion to ensure the efficiency of data transmission. However, in order to reduce hardware costs and data buffering delays, most switches are configured with a limited number of buffers. Therefore, when there is a burst of traffic in the network, congestion is easy to occur, and data packets may be dropped. Existing studies have shown that burst traffic is the main cause of data packet loss at the network edge layer and aggregation layer. Therefore, it is necessary to avoid the impact of packet loss caused by burst traffic on the network as much as possible. [0003] In terms of network congestion control methods, the existing technologies mainly have the following i...
