All, Agreed to a point. But the back plane is several Terrabits. Possibly alleviating the current situation. A pair would be nice, but since the chassis' can have up to four power supplies and multiple PFEs we'd be redundant to the port as we are currently. Chaining devices still continues to provide enigmatic problems and solutions. Where a chassis would be a better solution all round, including providing the possibility for 40/100 Gig connections, especially to the Content providers. Chassis architecture can provide some degree of assistance in the current meta and distribution, the main point I would make is the chassis provides a flexible future. I do agree, a full suite of EX4550's with the 128Gig vpc connections would be a solution to our current dilemmas.
