TRILL, what is it?

This is a half baked post today, but it is an attempt to get back into the swing of things.

One of the things on the “lists of posts to finish” is one on the emerging Data Centre technologies and the benefits that they they offer, or could offer, to the network Architect and Engineer. There have been some great articles written lately covering off NIV, FCoE and the odd article, and I do mean odd, about the wonders of RDMA over Converged Ethernet. One of the things I wanted to write about was TRILL. In a nutshell, TRILL is a L2 path selection algorithm (link state) designed to replace our good friend spanning tree.

Rather then bore you with my version of how it works and the benefits of TRILL to today’s design issues, have a look at the awesome write up done by @bradhedlund over at Cisco.

I’m still trying to find some time to get the back log of posts out of my head an onto paper/or here.
