US 2022/0286532 A1 · METHOD AND APPARATUS FOR OBTAINING SHARED MAXIMUM SEGMENT SIZE MSS

Abstract

This application discloses a method and an apparatus for obtaining a shared maximum segment size MSS, and a storage medium, and belongs to the field of communications technologies. In this application, a first device may obtain a first parameter after a Transmission Control Protocol TCP connection is established, obtain a first MSS based on the first parameter, and further obtain a first shared MSS based on the first MSS and a second MSS. After the TCP connection is established, when a parameter of the TCP connection changes, the first device updates a shared MSS based on a changed parameter, and may use an updated shared MSS to transmit a packet. This helps save network resources and improve transmission reliability.

Dependent claims

A method for obtaining a shared maximum segment size (MSS), comprising:

obtaining, by a first device, a first parameter after establishing a Transmission Control Protocol (TCP) connection, wherein the first parameter corresponds to the TCP connection;
obtaining, by the first device, a first MSS based on the first parameter;
and
obtaining, by the first device, a first shared MSS based on the first MSS and a second MSS sent by a second device.

1 more element

An apparatus for obtaining a shared maximum segment size (MSS), used in a first device, wherein the apparatus comprises:

a memory storing instructions;
and
a processor coupled to the memory to execute the instructions to:
obtain a first parameter after establishing a Transmission Control Protocol (TCP) connection, wherein the first parameter corresponds to the TCP connection;
obtain a first MSS based on the first parameter;
and
obtain a first shared MSS based on the first MSS and a second MSS sent by a second device.

4 more elements

A non-transitory machine-readable storage medium having instructions stored therein, which when executed by a processor, cause the processor to perform operations, the operations comprising:

obtaining a first parameter after establishing a Transmission Control Protocol (TCP) connection, wherein the first parameter corresponds to the TCP connection;
obtaining a first maximum segment size (MSS) based on the first parameter;
and
obtaining a first shared MSS based on the first MSS and a second MSS sent by a second device.
