Title:
PACKET FORWARDING METHOD AND SYSTEM, STORAGE MEDIUM, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/184169
Kind Code:
A1
Abstract:
Embodiments of the present invention provide a packet forwarding method and system, a storage medium, and an electronic device. The method comprises: a source node located in a first SR-MPLS domain sends, on the basis of a segment routing policy (SR-Policy), a packet to a destination node located in a second SR-MPLS domain, wherein a list of SR-Policy segments of the packet comprises an BSID in the form of an MPLS label for allowing the packet to pass through an SRv6 domain between the first SR-MPLS domain and the second SR-MPLS domain; a first border node replaces, after receiving the packet, the BSID in the form of the MPLS label with an SRv6-Policy of which a destination address is a second border node, and forwards the packet on the basis of the SRv6-Policy; the second border node decapsulates, after receiving the packet, an IPv6 header of the packet and an extension header thereof according to behavior indication information carried in the SR-Policy, and queries an MPLS label forwarding table according to the MPLS label to forward the packet in the second SR-MPLS domain, until the packet is forwarded to the destination node. The present invention achieves forwarding of packets across SR-MPLS domains and an SRv6 domain.
