Abstract

The invention discloses a maximum transmission unit consultation method and a data terminal and comprises: the data terminal receives a first request message which is sent during communication protocol link connection establishment of a user terminal and carries a maximum transmission unit (MTU) of the user terminal; updating the MTU of the user terminal carried in the first request message into a path MTU; sending a second request message carrying the path MTU to a server; receiving a first reply message which is returned by the server and carries the MTU of the server; updating the MTU carried by the server in the first reply message into the path MTU; and sending a second reply message carrying the path MTU to the user terminal. By means of the maximum transmission unit consultation method and the data terminal, network performance can be improved.

Description

technical field [0001] The invention relates to the field of data terminals, in particular to a maximum transmission unit negotiation method and a data terminal. Background technique [0002] With the development of science and technology, networks using various communication protocols play an important role in people's daily work, study, and every aspect of life, and network performance has also received great attention. The Maximum Transmission Unit (MTU) refers to the size of the largest packet that can pass through a certain layer of a communication protocol, which is the sum of the maximum segment size (Maximum Segment Size, MSS) and the length of the message header. in bytes. When some communication protocol links establish a connection, such as Transmission Control Protocol (Transmission Control Protocol, TCP), the user terminal and the server will negotiate, send their own MTU to the other party through a handshake message, and select from the user terminal MTU and ...
