Intercloud federation using via semantic resource federation API and dynamic SDN provisioning

摘要

Intercloud refers to a transparent and voluntary federation of Computing Clouds analogous to the way the Global Internet or Global PSTN/Mobile Telephony works. Individual Service Providers join into a predefined Common Channel Signaling network (Backbone IP Routing protocols in the case of the Internet, the SS7/IN network in the case of the PSTN/Mobile Telephony Network) and exchange infrastructure. Once federation relationships are identified through protocols which transit the Signaling network, a Bearer network relationship is established where the user data is transited. This paper describes the workings of the Intercloud system in terms of the details of the Intercloud Federation API, which transits the signaling network, and how this API is used to dynamically provision a Software Defined Network (SDN) based Virtual Private Cloud (VPC) using Virtual Private networks (VPN), creating the federating bearer network for the transparent federation. The Intercloud Federation API is based on a semantic definition of resources, Service Level Agreements (SLA), and Bearer Network Provisioning Metadata.
