Hi Folks,

We proposes two drafts on the new type of segment in the segment routing: draft-li-spring-tunnel-segment-00 and draft-li-pce-tunnel-segment-00.

-- draft-li-spring-tunnel-segment-00 proposes the possible usecases such as reduce SID stack depth of SR path, span the non-SR domain or provide differentiated services. This document also proposes the difference between the adjacency segment and the tunnel segment. These work will help to understand the necessity and advantages of tunnel segment in some application scenarios. Then we define the forwarding mechanism and protocol extensions requirements on tunnel segment.

-- draft-li-pce-tunnel-segment-00 proposes the possbile PCEP protocol extensions for the tunnel segment based on draft-li-spring-tunnel-segment-00. The protocol extensions are introduced for two different applications: 1. PCEP extensiosn from PCC to PCE; 2. PCEP extensions from PCE to PCC.

Hope you could have interest in these drafts, help review or refine. You comments will be appreciated.

Thanks & Regards,

Zhenbin (Robin)
