Hi,
Few comments about this draft.

a)      "A new mechanism, to be defined, may also enrich the packet transition in a service chain by passing service-specific information and/or  information pertaining to preceding services in the chain along with the packet being processed".    Not clear what this means and if there is no intention to elaborate on this why include here.

b)      ".... it is important to have a view of the Virtual Network (VN) topology (VNT)...". It is not clear why. Could you please elaborate why it is important.

c)       section 3.1, service topology,  this could be lot of information.

d)       sec 3.2, most of the discussion is about the generic QoS/utilization related statistics counters. Are there any service chaining (the topic of this draft) specific counters requirements (e.g. FW, DPI etc) mentioned in section 3?

e)      Suggest to add a section that should list the scale requirements for the use cases covered in the draft

Thanks,
Iftekhar
