Title:
A METHOD FOR ESTABLISHING SEGMENT ROUTING FOR IPV6 TUNNEL
Document Type and Number:
WIPO Patent Application WO/2019/011114
Kind Code:
A1
Abstract:
The present invention provides a method for establishing Segment Routing tunnel based on IPv6 data-plane by using a path computation element communication protocol (PCEP). The method includes generating, by a path computation element (PCE), a first PCEP message, wherein the first PCEP message comprises indicating information and segment identifier (SID); and wherein the indicating information indicates that the SID is an IPv6 prefix of a node in a tunnel. A first path computation client (PCC) receives a first PCEP message from a PCE and the first PCC establishes a SRv6 tunnel from the first PCC to a second PCC.
