Abstract

The invention provides a message processing method and device, used for solving the problems that fast retransmission and a congestion control mechanism are started as out-of-order messages occur in amessage transmission process and then message transmission efficiency is reduced. The method comprises the following steps: message processing equipment determines a fact that the out-of-order messages exist in messages received by a message receiving terminal; and the message processing equipment receives a DUPACK message specific to the out-of-order messages fed back to the message processing equipment by the message receiving terminal , and discards the received DUPACK message.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method and device for processing messages. Background technique [0002] In a network communication process, a reliable connection is usually required to realize reliable transmission of data packets, wherein Transmission Control Protocol (Transmission Control Protocol, TCP) is a protocol capable of realizing reliable transmission of data packets. [0003] In network communication based on the TCP protocol, the TCP sender and the TCP receiver communicate through TCP messages, wherein the TCP messages include TCP data messages and TCP confirmation messages. A TCP data message is a message containing a data segment (segment), and the TCP data message header includes a Transmission Sequence Number (Transmission Sequence Number, TSN) used to identify the sequence of the TCP data message. If the TCP data message is being transmitted Packet out-of-sequence (mess...
