  • Method for establishing segment routing for IPv6 tunnel
    Patent number: 11962496
    Abstract: A method for establishing a segment routing (SR) tunnel based on an Internet Protocol version 6 (IPv6) data plane using a Path Computation Element Communication Protocol (PCEP) 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; receiving, by a first path computation client (PCC), the first PCEP message from the PCE; and establishing, by the first PCC, a Segment Routing over IPv6 (SRv6) tunnel from the first PCC to a second PCC.

  • Method for establishing segment routing for IPv6 tunnel
    Patent number: 11483235
    Abstract: A method for establishing Segment Routing (SR) tunnel based on Internet Protocol version 6 (IPv6) data-plane using a path computation element communication protocol (PCEP) 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 an SR for IPv6 forwarding plane (SRv6) tunnel from the first PCC to a second PCC.

  • Method for Establishing Segment Routing for Ipv6 Tunnel
    Publication number: 20200153732
    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.
