Network Dimensioning Based on Percentage of Access Link Capacity Carrying Premium Traffic

Vasilios Siris, Georgios Fotiadis
2006 2006 IEEE International Conference on Communications  
An important feature of the two worst-case algorithms is that they allow admission control decisions to be based solely on the availability of bandwidth for premium traffic at the access links.  ...  We apply and compare the three algorithms for the Greek Research and Technology Network (GRNET), which currently uses the third algorithm for its premium IP service.  ...  An important advantage of the latter two algorithms is that admission control decisions can be based solely on the availability of bandwidth for premium traffic at the access links.  ...
