Problems solved by technology

[0005] In the process of target data transmission, due to the failure of transmission equipment or the surge of network load, the actual degree of chaos in the network will become serious. In this way, a large number of data packets may arrive at the receiving end out of order, but these data packets are not lost. , there is no need to resend, then if these packets are still resent, it will consume a lot of network transmission resources

Embodiment Construction

[0057] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0058] The embodiment of the present invention provides a method for setting network out-of-sequence values. The method can be implemented by network equipment. The network equipment can be a data sending end, such as a server, a computer, etc., and a process for data transmission can be installed on the network equipment. , the sending end can send data from different transmission links to different receiving ends through this process, and the receiving end can be other network devices or terminals. The network device may include a processor, a memory, and a transceiver. The processor can be used to perform the processing of setting the network out-of-order value in the following process, and the memory can be used to store the data re...

Abstract

The invention discloses a method and a device for setting network out-of-sequence values, belonging to the technical field of data transmission. The method includes: receiving a D-SACK message corresponding to the first data packet of the target data, and looking up the out-of-order predicted value corresponding to the first data packet in a locally stored out-of-order value prediction table, wherein the out-of-order The predicted value is the network out-of-sequence value determined according to the data packet reception status of the target data when the first data packet is resent, and the current network out-of-order value is set according to the out-of-order predicted value of the first data packet value. By adopting the present invention, network transmission resources can be saved.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a method and a device for setting network out-of-sequence values. Background technique [0002] In the process of data transmission in the wireless network, due to network failure or equipment failure, the data transmission may fail. At this time, the sending end needs to resend the data. [0003] The sending end generally presets a network out-of-sequence value for evaluating the degree of network confusion. After the sending end sends the target data, if a certain data packet received by the receiving end does not arrive in sequence number from small to large (such as data packet 1-10 are sent sequentially. After receiving the data packet 5, the receiving end receives the data packet 8) and will feed back the SACK (Selective ACK) message corresponding to the data packet to the sending end. When the cumulative number of SACK messages received by the sending end is gre...
