| Abstract: | Abstract: The differentiated services (DS) architecture provides a framework for the scalable provisioning of multiple service levels in the Internet. Its definition and initial work have
concentrated mainly on per-hop behaviors (PHB) and mechanisms at each DS domain. Equally important is what happens between DS domains. Thanks to the exibility of the architecture, it is the providers choice how to interconnect with peers. In principle, traditional, static peering agreements work together with DS, but they do not offer the exibility and dynamics needed in an electronic market for network capacity. Therefore, we look at dynamic service level agreements at the inter-domain level. Such agreements are established by software entities called traders. These traders follow market-based principles to decide which contracts will be bene cial. In particular, traders compare the offers made by neighbor providers and select the most interesting ones. This selection of peer services creates competition among providers and integrates route selection based on service level and destination. We describe and implement a framework for service level agreement trading. We show the basic workings and rst performance results of SLA trading using specific traders and an experimentally de ned PHB in a simulation environment.
