Routing Without Tears, Bridging Without Danger
Why is route calculation done at both layers 2 and 3 of networking? Is one better? Do we need both? This talk explains the historical accident by which bridging was conceived and the properties that make it attractive, and dangerous, today. The talk discusses new work being done in IETF known as TRILL (TRansparent Interconnection of Lots of Links), which combines the advantages of bridges (layer 2 forwarding devices) and routers (layer 3 forwarding devices).
Dr. Radia Perlman is a Distinguished Engineer at Sun Microsystems Labs. Radia is the creator of the spanning tree algorithm used by the bridges (switches) of the Internet. She notes the irony that this work discussed in this talk might kill spanning tree bridging.
