Authorized value processing method, device and network system

Abstract

The invention discloses an authorization value processing method and device and a network system, belonging to the field of network technology. The method comprises that a back pressure is generated when the data bulk cached at the reception end is greater than a back pressure threshold; a first authorization value is determined according to a current authorization request value of a first type of queue; and the first authorization value is issued to the first type of queue, the first authorization value is the difference between the current authorization request value of the first type of queue and a first request threshold, and the first request hold is not lower than the difference between the preset maximal authorization value at the transmitting end and the flow control threshold. The authorization value can be issued in advance, time from that the reception end cancels the back pressure to that the transmitting end starts sending data is shortened, time from that the transmitting end generates flow control to that the transmitting end starts sending data is also shortened, and the drop rate of the transmitting end is reduced. The first authorization value issued in the period that the reception end generates the back pressure can ensure that the transmitting end does not send data, and flow outburst is avoided.

Description

technical field [0001] The present invention relates to the field of network technology, in particular to an authorized value processing method, device and network system. Background technique [0002] The network system includes a receiving end and a sending end. The receiving end can issue an authorized value to the sending end. After obtaining the authorized value, the sending end sends data to the receiving end according to the authorized value issued by the receiving end, and the receiving end caches the data. Then release the data from the cache and process the data. [0003] However, the amount of data that can be cached by the receiving end is limited. When the amount of data cached by the receiving end is greater than the back pressure threshold, the receiving end will generate back pressure and stop sending authorized values, and the sending end will not be able to obtain new authorized values. Data can only be sent according to the existing authorization value, a...

AI Technical Summary

Problems solved by technology

[0005] After the receiving end cancels the backpressure and sends the authorized value to the sending end again, the sending end will need a period of time to accumulate the authorized value to ensure that the remaining authorized value is greater than the flow control threshold, and then the flow control will be revoked, and the data will be sent from the receiving end. It takes too long for the end to withdraw the backpressure and the sender to start sending data

[0006] Furthermore, the amount of data that the sender can cache is limited. During the period from when the sender generates flow control to when it starts sending data, the sender does not send data to the receiver, and the data at the sender is blocked. Once the data at the sender If the amount exceeds the maximum amount of data that can be cached, the excess data will be discarded, and the discarding rate is high
