An Experiment on the Load Shifting from Service Registry to Service Providers in SOA

In SOA (Service-Oriented Architecture), the service match making process is conducted in the registry. When the amount of requests increases, the communication load between registry and requesters could also increase, which may overload the registry and result in a longer response time. This could be worse when the service match making is based on semantic rather than syntax. To address this issues, we proposed, in this paper, an extension of the SOA to reduce the response time and registry loading by reallocating the major service match making tasks to service providers. An experiment is also conducted to compare the performance of the proposed architecture with original SOA to illustrate the feasibility of the proposed approach.
