Software defined Bearer Intercloud networks semantic-based network exchange for the IEEE P2302 Intercloud approach

In the contemporary cloud computing environment, the various cloud providers adopt different architectures for their systems and usually these are not compatible. The scalable exchange of information about these heterogeneous resources is often not addressed; still this represents an interesting challenge, since different Cloud systems and vendors have different ways to describe and invoke their services, to specify and communicate requirements. Hence a way to provide a common access to Cloud services and to discover and use required services in Cloud federations is highly desirable. The IEEE P2302 Intercloud approach is to define a scalable architecture and to adopt the OMN (Open-Multinet) ontology for supporting its operation. Our work specifically describes the inner workings of the Intercloud system in terms of the Intercloud Federation Application Programmers Interface (API), which are in turn based on the semantic definition of resources, Service Level Agreements (SLAs), and Bearer Network Provisioning Metadata.
