Routers in Data Centers

[Venkatesh Sriram <vnktshsriram () gmail com>]

Hi,

Can somebody educate me on (or pass some pointers) what differentiates
a router operating and optimized for data centers versus, say a router
work in the metro ethernet space? What is it thats required for
routers operating in data centers? High throughput, what else?

Thanks, Venkatesh
