Abstract:

To solve the difficult problem of long probing delay and inaccurate probing results in endpoint admission control method, a joint local and end-to-end admission control algorithm is proposed, which introduces local probing of access network besides end-to-end probing. Through local probing, the algorithm accurately estimates resources status of access network. We show through simulation that this algorithm can improve admission control performance and reduce users’ average waiting time when access network is heavy-loaded.
