John Herbert of Lame Journal comments:
When I wrote about TRILL a while back I also mentioned Shortest Path Bridging (SPB) in passing, with the intent to write a post on it. As it turns out, I never got round to it (oops), but at that point the big players were either saying they weren’t going adopt either (Juniper, because of QFabric) or were supporting TRILL (e.g. Cisco, Brocade). SPB was the domain of companies like Avaya, HP and Nortel and it wasn’t very clear whether it was going to succeed or not.
Shortest Path Bridging is making headway in enterprises due to its ease of deployment on existing hardware. Ready on for John’s take on SPB from Networking Field Day 7.
