| Abstract: | By reserving transmission capacity on a series of links from one node to another, making a virtual path connection (VPC) between these nodes, several benefits are obtained. VPCs will enable segregation of traffics with different QoS, simplify routing at transit nodes, and simplify connection ad-mission control. As telecommunications traffics experience variations in the number of calls per time unit, due to office hours, inaccurate forecasting, quick changes in traffic loads, and changes in the types of traffic (as in introduction of new services), there is a need to cope for this by adaptive capacity real-location between different VPCs. The focus of this paper is to introduce a distributed approach for VPC management and compare it to a local and a centralised one. Our results show pros and cons of the dif-ferent approaches. |
