Dhruv,

You raise a very good question. What makes us think that the largest network 
diameter is 16? Next year, it may be 32! Maybe we need to rethink this 
requirement.

An IPv6 routing header can contain no more than 2,048 bytes. Therefore, an SRH 
without compression can support an SR path that contains as many as 127 
segments. Maybe the requirement should be rewritten as follows:

NEW>
   Description: The compression proposal MUST be able to represent SR
   paths that contain up to 127 segments.

   Rationale: The SRH, without compression, can represent SR
   paths that contain up to 127 segments. Compression mechanisms must have the 
same capability.

   Metric: The compression proposal must be able to steer a packet
   through an SR path that contains up to 127 segments.
<NEW

This shouldn't be too controversial because all of the proposed compression 
mechanisms can satisfy the requirement.

                                                                                
                                 Ron

In Section 4.2.3

Description: The compression proposal MUST be able to represent SR paths that 
contain up to 16 segments.
Rationale: Strict TE paths require SID list lengths proportional to the 
diameter of the SR domain.

It would be nice to include why the number "16" in the rationale.
