Message transmission timeout processing method based on SRv6 programmable network

The invention discloses a message transmission timeout processing method based on an SRv6 programmable network, and aims to solve the problem that message transmission timeout in an IP network cannot be judged and processed. The technical scheme is that the method comprises the following steps: designing a message transmission timeout processing protocol format, and constructing a network message transmission timeout processing system consisting of a message sending node deployed with a message construction sending module and M message forwarding nodes deployed with message timeout processing modules; enabling the message constructing and sending module and the M timeout processing modules to work in parallel in a matched mode, and enabling the message constructing and sending module to manage network flow transmission aging time and package network messages transmitted by network applications into timeout control network messages; enabling the M timeout processing modules to make judgment in parallel and pro
