Hybrid connection admission control in ATM networks
Hiroshi Saitō · 2003
The author proposes a new connection admission control (CAC) method called hybrid CAC. The hybrid CAC provides two cell loss rate classes, and requires the declaration of each virtual circuit's (VC's) peak cell rate as a traffic parameter. The admission of a low-priority VC is decided based on the measured number of cells arriving from connected VCs and the specific peak rates. The bandwidth assigned to a high-priority VC is the specified peak, but the bandwidth that is not actually used by the high-priority VC can be used by low-priority VCs. Therefore, the hybrid CAC attains high utilization and high quality for high-priority VCs with only the peak cell rate needing to be specified.>
