said by injaview :Actually currently working on the TWC core network in NC, I actually know what equipment is in there today. And it is current router hardware from multiple vendors in the core.
I seriously doubt you've worked with the core part of the network that handles the hundreds of gigs of traffic that goes through it.
Actually, I worked core, metro and access edge. The backbone isn't the problem, especially with some of the newer equipment they were planning on installing in places. It is further down into the metro and access portions of the network where older and outdated equipment could be found.
