RE: [RPRWG] Rings and Ringlet?



Title: RE: [RPRWG] Rings and Ringlet?
John, David, et al,
 
We did try to use ring and ringlet as defined in the Terms and Definitions (although it is quite possible that we slipped somewhere).

David,

Your question is a good one. Let me see if I can clarify.

One of the things we have not had the time to do thoroughly at this point is to scrub the various portions of the draft for consistent use of terminology. Where possible, we tried to use the terms and definitions as proposed by the T&D sub-committee, realizing that this, to some extent, is a moving target as well.

On this particular question, I think there is good agreement on the following definition:

  ringlet: A closed unidirectional path formed by an ordered set of stations, and the links interconnecting stations, such that each station has exactly one link entering the station and one link exiting the station.

  ring: The collection of stations and links forming a resilient packet ring. (2) The set of congruent ringlets forming a resilient packet ring.

I'll let Jason and the committee that worked on the topology discovery draft comment on whether they were rigorous in their application of the above definitions.

Hope this helps,

john

        I am relatively new to the Optical networks. So please pardon my
ignorance.
        In the Unofficial Draft for Topology Discovery
mechanism(jcf_topodraf_02.pdf) talks about rings and ringlet.
        What is the difference between a ring and a ringlet?

Thanks in Advance.
