In fact, what you've just described is called a Soft PVC. The argument is that there's less configuration to do if you use dynamic SVC setup than PVCs. Of course, this isn't a big issue in a small network. Remember, though, that manageability is one dimension of scalability. > >I suppose it's possible to have networks where connections >aren't up all the time, but when they are you need the >capabilities inherent in ATM.
