context multi-service, multicast, connectionless can be flowless
– simple open no PSTN billing to rely on generalised technology allows many specific
business models– future is …? computer-computer comms?– not just Web, audio & video

admission control is a delusion
probability of session blocking with CAC = probability of packet block without CAC
control session admission improve intra-session utility reduce inter-session utility
just moving the problem mechanism to allow user to choose

limitations
full metering still to be integrated– meter rules sent with tariff?
reliability of end customer OS user acceptance of dynamic pricing user acceptance of dynamic provider code hogging?

exception peering
exceptional failures– loss of a packet subject to reservation– excess delay of a low latency packet
no customer revenue no recriminations between ISPs
– no “who lost packet?”– no “who delayed packet most?”
assume peers sufficiently dimensioned
