Abstract:
A high speed connection admission controller based ontraffic monitoring comprising:connection admission control (CAC) means for determining whether or not to connect a new call after comparing a peak cell rate (PCR) of the call with a previous available bandwidth when the call having the peak cell rate (PCR) of homogeneous traffic is requested to be connected, and for computing a new available bandwidth when the new call is admitted to be connected;buffer means for storing asynchronous transfer mode (ATM) cells which are introduced via the connection admission control (CAC) means by a certain time period when the call is admitted to be connected;server means for computing a traffic monitoring value which is output from the buffer means; andcapacity assignment control means for computing a probability distribution function for a cell number from the traffic monitoring value which is output from the server means, and for computing a real equivalent bandwidth according to the probability distribution function, to feedback output the real equivalent bandwidth to the connection admission control (CAC) means.
