Hi all, it's great to see a draft and this much support for a UNI model which seems necessary when offering support out to the edge of "connection oriented services". This is very similar to the original OIF UNI work, until a huge issue arose over supported address types. The initial thrust was for only IP address types (v4 and v6). However this didn't fly with a bunch of folks with installed networks using NSAPs. However it was never really clear, to me, that NSAPs were needed, i.e., the optical control plane was to be IP based and any other "addresses" could be viewed as "names" and translated when and if necessary. Note that all previous SONET/SDH standards specified OSI stacks on the "in band" data communications channels (if you were wondering how we got into this mess). This is an area that could use a bit of thinking since from the ITU-T perspective other (non IP) address are desirable. And it would be nice to harmonize the work at the various standards bodies.
