I guess the other question would be "why not"? If, as Adrian mentions, we constrain the its use as defined in G.694.1 while leaving room for growth, at least the encoding would be more likely be reused (as opposed to the WSON -> SSON). For what is worth, individual drafts that are considering extending RSVP-TE for signaling media channels would also be affected. The underlying idea is to propose new types for the sender template and the flowspec in the flow descriptor to accommodate for the requested and allocated slot width. Right now, only the "m" parameter is encoded with the corresponding padding/reserved bytes. Regards, Ramon PS: much like Adrian's draft, the label encoding proposed in http://tools.ietf.org/html/draft-li-ccamp-flexible-grid-label-00 also took into account the fact that a reduced number of bits would suffice to cover G.694.1 > On 2014-01-31 19:44, Adrian Farrel wrote: >> Hi Gabriele, >> >> IIRC this topic has come up in various discussions. >> I think the discussion ran aground when we tried to understand what >> ITU-T SG15 >> Q6 data plane capabilities this increased value of "m" modelled. >> >> I believe that we could easily increase the size of the m field, but >> as I >> understand the status of the Q6 work, we would still need to >> constrain its use >> as defined in G.694.1.
