> What kinds of routers can route at near wire speeds a bunch of ports at > 155Mb ATM? None right now. Gigarouter can handle it theoretically, but... I'm being picky, but it's a moot question since doing wirespeed OC3c using ATM is impossible in of itself. Hell, mapping of SONET framings to ATM cells take off about 6 mbps right there. Anyway, until then you have a router that can do this, there always are ATM switches + cluster of routers. True, Netstars's Gigarouter is the fastest one shipping now. Its aggregate advertised bandwidth is 16 Gbps using a 16x16 matrix of non-blocking crosspoint switches. I have assembled a list of several best effort packet routers including known research efforts: http://www.whnet.com/wolfgang/giga.html Corrections and additions are welcome.
