Agent based Dynamic Policy Contract Enforcement in Service Oriented Network

Abstract: In our project, there is service oriented architecture (SOA) plays a vital role for integrating the legacy systems with new technologies in the enterprise world. A service is usually done by a client service contract (CSC). It specifies the requirements the rate at which a service should be accessed, and limits it to no more than a number of service requests during an observation period. They are several approaches are used. Such approaches are both static and dynamic credit based strategies. These have been developed to enforce the rate specified in the CSC. Existing approaches leads to some problems like starvation, approximations and rapid credit consumptions. For this, we propose and use the algorithm called DOWSS. It is mainly used for service traffic shaping. It is mostly show via simulation process. It has several advantages such as it eliminates the starvation, approximation issues and avoids rapid credit consumption. It overcomes the disadvantages of existing approach.
