I've just stumbled across the article The 5 hottest topics on SearchTelecom. Not surprisingly, MPLS is the top one, with Routers and Switches being the second. It's interesting to see that MPLS is still a very hot topic more than seven years after we've written the MPLS and VPN Architectures book … and I'm pretty proud that two of my articles in that category made it to the Editor's picks :).
