ABSTRACT:
A device for Connection Admission Control for an ATM switch, intended for admitting to the switch a requested ATM connection of the DBR type, such that the “Quality of Service” of all ATM connections of the DBR type in said switch continues to satisfy certain conditions. For the composite traffic stream of DBR connections at an output port with capacity C, a single buffer with capacity B is available, while as boundary condition it holds that the total average load of the output port does not amount to more than ρ×C, where ρ is a constant with a value between 0 and 1. The CAC device comprises two sub-devices, which each execute a—rather complex—partial calculation, resulting in a positive or negative admission signal. The new ATM connection is only granted admission to the switch if both sub-devices emit a positive admission signal.
