Talk:Network topology

Need some ideas for more topologies? Think wireless: broadcast, multi-hop. Markus Baumeister 15:17, 2 April 2007 (CDT)

Emphasis on topology vs. on failure/recovery modes

There are a number of topologies that apply when high availability is involved, not just in physical media such as SONET/SDH/NGN, but in things like the MPLS recovery framework (RFC3469 Framework for Multi-Protocol Label Switching (MPLS)-based Recovery. V. Sharma, Ed., F. Hellstrand, Ed.. February 2003)

Some things to consider, with fault tolerant rings, are:

• 1+1 data flows concurrently on both rings, and the endpoint decides which to use
• 1:1 data flows on an active ring, but can fail over to a protection ring. The failover, incidentally, can be for less than the entire ring--a failing station or media segment can be bypassed
• N:M there are N active rings protected by M backup rings, such that N>M

As usual Howard I end up learning more from your commentary than from attempting to write the article itself :) Eric M Gearhart 20:22, 3 September 2008 (CDT)
