The Pluris load-balanding approach allows gradual shifting of load between pipes while doing native IP routing. >The VC table >has a speed forwarding advantage over the IP radix tree. The upper levels of the radix tree fit nicely in L1 cache, so the real advantage of VC table is far smaller. >The radix >tree may have a space advantage due to aggregation. Radix tree is O(log n) from size of the network. (n is the number of hosts). VC table is O(n), at least at some switches. >That in a >nutshell is the IP vs ATM flamewar (did I miss anything - ommisions >private mail unless it was major). Nah, it is much funnier. I plan to publish my comments on the issue at Pluris web site shortly. >The interest in IP switching >(CSRs, tag switching, IP switching proposal de jour) comes from a >desire to combine the best of the two.
