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?
While this question has many dimensions and there is no real definition of either I suspect that what many people mean when they talk about a DC routers is: Primarily Ethernet interfaces High port density Designed to deal with things like VRRP / VLAN / ethernet type features. Possibly CAM based, possibly smaller buffers. Less likely to be taking full routes. This is very similar to the religious debate about "What's the difference between a 'real' router and a L3 switch?" Just my 2 cents. W
Thanks, Venkatesh
