Correction: The way DRAM works, it cannot handle high packet rates. Also note that the PCI-X bus tops out in the 7 to 8 gbps range and it's half-duplex. High-rate routers try to keep the packets in an SRAM queue and instead of looking up destinations in a DRAM-based radix tree, they use a special memory device called a TCAM. http://www.pagiamtzis.com/cam/camintro.html Regards.
