Subharthi Paul, Raj Jain, Mohammed Samaka, Aiman Erbaud, "Service Chaining for NFV and Delivery of other Applications in a Global Multi-Cloud Environment," 21st Annual International Conference on Advanced Computing and Communications (ADCOM) 2015, Chennai, India, September 18-20, 2015, DOI: 10.1109/ADCOM.2015.18


Network Function Virtualization (NFV) allows Internet Service Providers (ISPs) to implement key function modules, such as, BRAS (Broadband Remote Access Server), IMS (Internet Multimedia System), etc. in virtual machines in a cloud environment. One of the key problems in NFV implementation is the placement of virtual machines (VMs) in clouds managed by different cloud service providers each with its own management interface. It would be helpful if the clients can implement their policies in a multi-cloud environment using a single interface. Our proposed solution is a modular multi-cloud management system called OpenADN that provides a common interface for resource allocation in a multi-cloud environment. The solution is also applicable to non-ISP applications, such as, banking, financial, and other sectors that need to use globally distributed multi-cloud resources. This paper presents a brief overview of the OpenADN architecture. The key feature of OpenADN is that multiple tenants can share the resources and all resource owners keep complete control over their resources. The data plane module of OpenADN is called OpenADN (Open Application Delivery Network). OpenADN has been implemented and brief details of implementation are also presented in this paper.
