Re: MS-SPring [Was: Moving forward with the CCAMP charter]



richard,

Dimitri,

"why (and where) ring topologies are suitable" ?

Transport networks (e.g. SONET/SDH, WDM, RPR) have been, and will
continue to be, widely deployed based on (dual) ring topologies in
the access/metro because they provide fast protection and reliability
whilst making efficient use of fibre.

I do not think this can be disputed so I don't understand where you
are coming from with this question?

while i do not see why this can't be discussed (e.g. there are dozens of studies available on this topic) and i can just point out that one can deliver fast (time efficient), resource efficient and reliable protection without using rings

therefore, it would worth having some operational feedback and state what are the real drivers and rationales if such topic is getting started i.e. what is the real appealing rationale behind this mechanism

note: these are just questions that i think where missing from most documents produced on this topic since so far and that are important to be addressed

last point you are mentioning RPR so what would be the interaction with the IPORPR WG ?

Regards, Richard
