Abstract

The present disclosure provides a message forwarding method, device and storage medium based on SDN segment routing networking, which are used to solve the technical problem that the SDN network supports the SRv6 segment routing protocol. The disclosed technical solution adds the SRv6 protocol stack on the OVS, adds the SRv6 protocol Function field allocation function of the Overlay network on the SDN controller, and uses the Openflow protocol to solve the problem of SRv6 forwarding under the SDN network architecture. The disclosed technical solution can support the SRv6 protocol to bear the Overlay service in the SDN network combined with the Openflow protocol and the Open VSwitch.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular to a message forwarding method, device and storage medium based on SDN segment routing networking. Background technique [0002] Internet Protocol Version 6 (Internet Protocol Version 6, IPv6) segment routing protocol (SegmentRouting IPv6, SRv6) is a combination of two network technologies, segment routing (Segment Routing) and IPv6, SRv6 uses the routing extension header (Routing Extension Header) carries a newly defined segment routing header (Segment Routing Header, SRH), and the SRH type number is defined as 4. A list of Segment segments is included in the SRH. A segment identifier (Segment Identifier, SID) is a 128-bit IPv6 address, mainly composed of two parts: a locator and a function. The Locator is in the high position, specifying the prefix length of the corresponding address, and the subsequent bits are used by the Function. Function is an ID valu...
