Dynamic Service Contract Enforcement in Service-Oriented Networks

By Yesid Jarma, Keerthana Boloor, Marcelo Dias de Amorim, Yannis Viniotis, and Robert D. Callaway

In recent years, service-oriented architectures (SOA) have emerged as the main solution for the integration of legacy systems with new technologies in the enterprise world. A service is usually governed by a client service contract (CSC) that specifies, among other 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. Several approaches, using both static and dynamic credit-based strategies, have been developed to enforce the rate specified in the CSC. Existing approaches have problems related to starvation, approximations used in calculations, and rapid credit consumption under certain conditions.
