Configurations in which this charging scheme seem more likely are those which include a wide-area ATM service provided by a carrier. For example, in a configuration in which two campus-area ATM networks are interconnected by a wide-area ATM service, it may be desirable to establish cut-through SVCs within the campus networks, but use existing VCs over the wide area. On the other hand, I don't know of any wide-area ATM services which currently offer SVCs; I think carriers have a number of technical issues to address before they can think about pricing for SVCs. -tjs
