Dear Nikhil :

I think if memory vendors able to designing and produce TCAM(Ternary Content Addressable Memory) memory, RLDRAM 2&3 and QDR-SRAM 2+ in 3d (stacking), also hardware designers using HMC (Hybrid Memory Cube), ASICs or FPGAs with 3D(stacking)structure and optical interlaken and optical backplanes big changing in high-end routers and switches, MPLS networks will be faster, improving performance and speed and reducing convergence time.
