| abstract: | Why is route calculation done at both layers 2 and 3 of networking? Is one better? Do we need both? This talk will explain the historical accident by which bridging was conceived and the properties that make it attractive, as well as dangerous, today. Given how confusing it is to have networking at both layers 2 and 3, how could it possibly make the world better to invent layer 2.5? This seminar discusses a new standard in IETF known a TRILL (TRansparent Interconnection of Lots of Links), which combines the advantages of bridges (layer 2 forwarding devices) and routers (layer 3 forwarding devices), while being compatible with existing bridges and IP nodes. |
