RE: [RPRWG] RFC 2892; The Cisco SRP MAC Layer Protocol






Ray, Don

Based on the objective approved by the 802.17 WG last meeting ("The 802.17 RPR
standard shall support a fully distributed access method without a master node
within the same ring"), there is no master in the RPR operation.
Hope that helps

Angela

Do the .17 objectives prevent the election of a master?  Clearly requiring a
specific node to be on the ring and be the master would not be a good design
point; however, it seems that having a process like 802.5's Active/Standby
monitor election may not be a terrible thing to have.
Has there been any direction set on this?

After reading through RFC2892, it is not clear to me how each node
"discovers"  which interface  is on which ring (i.e. inner or outer).

I'm not suggesting we follow this implementation, but I am curious how the
assignment is done.

 It could be done with a master device, but I believe that goes against one
of our objectives, I'd know if they were posted:)

It could be hard coded, but that might limit flexibility.
