The real problem, IMHO, is that we are still looking at solutions which require packets to be transmitted from client to server through the infrastructure of a network. The routing and switching of packets is now old technology compared to the routing and switching of higher layer objects through technologies like hierarchical proxy caching. > Of course the variables are incredible in attacking the solution to > faster switching.

Or they are achieved through the elimination of the bulk of end-to-end packet transfer. Instead of using devices such as routers and switches which are unaware of the application protocols that are being used, application proxies with caching can add much more intelligence to the infrastructure components. > I could babble on to infinity on this subject, there are so many > ways to implement faster routing or switching!

But I also feel that new technologies that reduce the requirement for routed or switched traffic are going to have a much bigger impact. Too much time is being spent on ways to optimize routing at the lower layers ... I believe the real solution will be routing at much higher layers than layer 3! > Tim I am not worried about the perceived threat of layer 3 switches > to Cisco.
