Why MIPS is just a number
By Gaurang Kavaiya
Millions of instructions per second doesn't always represent the true computational capability of a device. Here's what you can do about it.

It's a bumpy road to high-speed networking
By Jag Bolaria
100GbE and greater density line cards can help provide the network bandwidth demanded by video traffic and mobile backhaul applications. Here is the latest on 40GbE/100GbE standards and the system interconnects required for line cards with densities of 100 Gbps and greater.
