Overview of Transparent Interconnection of Lots of Links (TRILL)
The Internet Engineering Task Force is developing a new shortest path frame Layer 2 (L2) routing protocol for multihop environments. The new protocol is called Transparent Interconnection of Lots of Links, or TRILL, and it is expected to be completed in the second half of 2010. TRILL will enable multipathing for L2 networks and remove the restrictions placed on data center environments by STP single-path networks. TRILL will also enable multihop capabilities for FCoE that will drive expanded adoption of FCoE in converged network environments. This paper will provide an overview of where TRILL fits, why it's important, and what it does and does not do.
