Hi,

Actually, I have a related question: can some one please explain how the
VPI/VCI values are actually managed in a switch. I mean what kind of
data structures do they use and what is the order of magnitude of their
search time. Linear allocation is simple, but it also will have to take
care of random allocations as in the case of PVC creation.

Thanks,

Mrityunjay
