I am interested in exactly what happens in a real world, ATM WAN environment, where the ATM has been provisioned from a major telco (AT&T or MCI, let's say). So let's ignore SVC's and PNNI and that kind of thing, because hardly any telcos use that stuff anyways, and deal only with PVC's For example, let's say I got some routers attached to this ATM cloud, through PVC's. I have decided to contract for, say, a stringent CBR CoS because I am running real-time video. Now, I would presume that the telco has most likely overprovisioned its ATM core, in order to earn more revenue, such that the telco can meet its SLA most of the time, but not all the time. So exactly what is the sequence of events when the telco ATM switches are unable to meet the CoS requirements of the ATM "call"? I would imagine that traffic-policing and CAC would come into play. But could somebody provide a precise sequence of events that would occur? Would an error message be seen on the router?
