The message forwarding method and device of the IPv6-based segment routing network provided by the present invention obtain the destination address in the IP address header of the message received by the routing node, and the destination address is composed of a network identifier, a node identifier, and a function identifier character and function parameters, and when the network identifier and node identifier in the destination IP address match the identifier of the routing node, the function identifier and function parameters in the destination IP address of the packet are used to obtain the The processing mode of the routing node to the message is to make the message continue to be transmitted in the segment routing network, according to the segment list included in the segment routing header in the message to the node identifier, The function identifier and function parameters are updated, so as to forward the message according to the updated network identifier and node identifier in the destination IP address, thereby effectively reducing the bandwidth occupied during the message forwarding process.
Description
technical field [0001] The present invention relates to the technical field of message forwarding, in particular, to a message forwarding method and device for an IPV6-based segment routing network. Background technique [0002] SRv6 is a source routing technology that carries a segment list through the SRH (Segment Routing Header) extension header, and each segment is marked with a 128-bit IPv6 address. Packet forwarding relies on information encoded in IP addresses. figure 1 It is the definition of SRH given in the IETF draft draft-ietf-6man-segment-routing-header-15.pdf. IETF draft-filsfils-spring-srv6-network-programming-06 describes in detail the encoding method of the segment identifier SID (Segment Identifier) in the form of an IPv6 address, which usually includes the node identifier Locator, function identifier function, and parameter Arguments. Among them, the node identifier Locator Represents a node, and the function identifier function represents the processi...
