Building Network-aware Composite Services with the GEMBus Framework

The GEMBus framework is intended to provide the necessary mechanisms to build federated composite services. Thus, it can constitute a key element in achieving cross-stratum optimization by combining network-layer events with service-layer operation knowledge. Taking advantage of the unique service perspective of the high level network operations we can use the GEMBus framework to compose the services with the network elements in order to build an enhanced and network-aware service. In this paper we give a brief description of the GEMBus architecture and discuss how to use it to build such services. We also evaluate the architecture using a proof-of-concept implementation and discuss the obtained results.
