Inter-cloud Networking Gateway Architecture

This paper presents a Cloud Networking Gateway (CNG) Manager, to enable networking of distributed cloud resources by authorized customers and to provide network control and configuration capabilities. The CNG Manager interconnects virtual machines, acquired from distributed heterogeneous resources and multiple providers, using generic gateways according to user connectivity requests. The CNG Manager is integrated with a "Cloud Broker" architecture for evaluation in the multiple providers context. The proposed framework extends and supports the current state of the art in cloud and software defined networks technologies with compatible connectivity control and management capabilities.
