Delay Based Congestion Detection and Admission Control for Voice quality in enterprise or carrier controlled IP Networks
Reservations based admission control, using Multi-protocol Label Switching (MPLS) is the leading method being considered by traditional carriers for maintaining Quality of Service (QoS) when deploying Voice over Internet Protocol (VoIP). In this research we explore an alternative to reservations bas...

| description | Reservations based admission control, using Multi-protocol Label Switching (MPLS) is the leading method being considered by traditional carriers for maintaining Quality of Service (QoS) when deploying Voice over Internet Protocol (VoIP). In this research we explore an alternative to reservations based admission control called Delay Based Congestion Detection and Admission Control (DBCD/AC), a form of Endpoint Admission Control. DBCD/AC is a method for edge devices, such as media gateways, to detect impending congestion in the core based on delay measurements and analysis. When impending congestion is detected, the edge devices refuse new incoming connections to the media gateways to mitigate the congestion. This research examines the characteristics of DBCD/AC and finds that DBCD/AC is a promising alternative to a reservations based admission control approach for enterprise or carrier controlled IP Networks. |
