Investigating Bandwidth Broker’s inter-domain operation for dynamic and automatic end to end provisioning

This paper deals with a distributed bandwidth broker that we try to extend in order to perform inter-domain operation. The basic issues for inter-domain operation are discussed and we try to approach the most demanding issues as the selection of the best inter domain routing path. Generally, we discuss three models for inter domain routing through bandwidth broker, analyzing their advantages. Also, a very important point that affects the interdomain operation is the SLAs between adjacent domains and the capability that a bandwidth broker should have to ask and perform dynamic negotiation. Finally, we analyze the best model and present how it should be incorporated in the existing distributed implementation.
