Embodiment Construction

[0071] The present invention is described in detail below with reference to accompanying drawing:

[0072] like figure 1 Shown, the present invention comprises the following steps:

[0073] The first step is to design the packet transmission timeout processing protocol format, the method is:

[0074] On the basis of the SRH message header, a new TLV is designed, named TTP TLV, to support and realize the processing of message transmission time overtime. The TTP TLV format is shown in Table 2. That is, in the SRH shown in Table 1, an 8-byte TTP TLV is used to replace the Optional TLV field.

[0075] The length and meaning of each field of TTP TLV are as follows:

[0076] Type: The length of the field is 8 bits, indicating the type of TTP TLV. The Type value of the TTP TLV is type_value, and type_value can be any unambiguous value within the range of 0 to 255 except 4 and 5, and type_value is preferably 101.

[0077] Length: The field length is 8 bits, and the value is b, w...

Abstract

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 process the transmission timeout of the network message, and discarding the timeout message. According to the invention, the problem that the overtime invalid message occupies network resources and possibly affects normal operation of network application in the existing IP network can be solved, so that no overtime invalid message exists in network transmission.

Description

technical field [0001] The invention belongs to the technical field of computer networks, and in particular relates to a message transmission overtime processing method based on SRv6 (Segment Routing for IPv6, ie segment routing in IPv6 network) programmable network. Background technique [0002] With the development of various Internet applications and 5G network technologies, the timeliness of message transmission is becoming more and more important. In many applications, once the message transmission time exceeds the aging time, the content of the message has become invalid, and there is no need to transmit it in the network. If the invalid message continues to be transmitted, network resources will be wasted; even when After the receiving end receives the failure message, it will have a negative impact on the normal operation of the network application. For example, in the field of industrial control, the arrival of the invalid control instruction message will disrupt th...
