I'm not sure how many TCP/IP stacks still set those bits; it may be necessary to have a router manipulate the bits after examining the port numbers of a connection.

Looks like a good place to use access lists that choose packets based on tcp, udp, and port number. If I could get a 45 Mbps circuit over high-latency geosatellite, one-way, I could use it for http and "push" traffic. The requests, outbound stuff, and interactive traffic would fit into a T1 under the ocean.

if you're interested in that, cisco's new CoS stuff uses precedence (extended access lists, mac address, ports numbers) to do just such a thing. it would be most useful if isp's could have concensus on the precedence "classes" to work across the multiprovider internet (may not be practical though). -brett
