A collaborative framework for enforcing server commitments, and for regulating server interactive behavior in SOA-based systems

Abstract

We are presenting a collaborative framework to enforce server commitments, and to regulate server interactive behavior in SOA systems. Trusted components collaborate to establish a network of enforcement components, one per server, to maintain proofs of what servers have committed with their clients and peer servers. The trusted components and the enforcement components also collaborate to make servers accountable for their commitments, and to enforce policies on the interactions between the servers and their clients/peer servers. In our framework, such collaborative efforts are explicitly stated in the form of policies to ease the management of collaborative processes. Our implementation is based on the LGI mechanism, complies with SOA standards, and does not require any change of the conventional SOAP-based protocol, the UDDI server, or the programs employed by servers and their clients.
