Title: An Admission Control Method in Differentiated Service Networks
Inventor: KIM SANG HA
IPC: H04L12/56
Filed: 2002-10-23
Abstract: PURPOSE: A connection admission control method in an Internet differentiated service network is provided to facilitate band management by allowing a bandwidth broker to manage only a band for a path level, and immediately accept an intra-network traffic change. CONSTITUTION: When an ingress edge node receives a new flow setup request(301), it selects a path by using a destination address(302) and checks whether the selected path is congested(303). If the path is not congested, the ingress edge node checks whether the amount of band remaining for a path level is larger than the requested band amount(305). If the amount of band remaining for a path level is larger than the requested amount of band, the ingress edge node subtracts the requested amount of band from the amount of band remaining for a path level, changes a path level band(306) and admits the new flow setup request(307). If the amount of band remaining for a path level is smaller than the requested amount of band, the ingress edge node performs a link level connection admission control(308).
