Hi Darren,






Sorry that my colleagues in IT department have not provided me with an upgraded email client to solve this problem.


For "global SID + local index", the related draft is draft-cp-spring-srv6-sid-allocation.

PSF

主 题 ：[Srcomp] Lossless Compression discussion update




--  
 Srcomp mailing list
 Srcomp@ietf.org
 https://www.ietf.org/mailman/listinfo/srcomp


Ron and I met today. We agreed to the following from my notes:


 


Ron will update the CRH draft to describe how the CRH data plane supports the RFC8402 adjacency SID functionality and document when it is needed (essentially pull the B1 CRH SID definition and discussion around when it is used into CRH).  When CRH is updated, the analysis draft can mark it as supporting lossless compression.


 


We agreed there is no need for an update to the CSID draft, the CSID proposal supports lossless compression as currently defined.


 


We did not get time to discuss SRv6 Base section so will do so via email for Friday.


 


Thanks


  Darren
