[Nsi-wg] section of possible architecture doc

Attached are two sections of a proposed architecture document. They are based largely on the Strawman doc with lots of cleanup and changes. Some of the biggest changes are 1) including adaptations at NS resources 2) defining a segment as [payload, route, attributes] where route is [edgepoint - edgepoint] 3) ete connection == [user service payload, route, attributes] I realize that you won't have time to read this before the call tomorrow, but it might be good to do a quick intro to make reading easier. The last bit is a glossary. John
