Abstract
A packet-based communications system or network is configured into multiple geographically distinct network bandwidth zones having interzone communications links with a configured maximum bandwidth. Adaptive bandwidth management based upon quality of server (QoS) measurement between two zones is utilized to dynamically raise or lower the maximum allowable bandwidth limit for the link between the two zones. When QoS between two zones degrades, the allowable bandwidth for new calls between the two zones is lowered to a point that assists in increasing the QoS back to an acceptable level (i.e., by blocking new calls or rerouting them). In one embodiment, the QoS information takes the form of QoS alarms generated and transmitted by active IP phones in the network bandwidth zone.
