Re: LCAS/VCAT

Hi,

I am interested in this work and think it's a useful functionality, but also have some questions on this draft:
1) In section 3.2, four scenarios have been described. Is there any requirement for the VCAT/LCAS capabilities for each scenario? or there is no such relationship between the scenarios and the VCAT/LCAS capabilities?
2) In section 4.2, for diversely routed VCG, what I understand is separately setup a set of LSPs which have same Ingress and Egress nodes, and associate these LSPs as a VCG at both Ingress and Egress nodes.  Could you elaborate how to manage/use the VCG? i.e. how to use the VCG to support the required service? I think at both ends of the VCG, the same signal adaptation should be required.

Thanks,

Dan
