Coordinating IT and network virtualisation to provide infrastructure as a service: A GEYSERS approach for the future internet

Abstract

In this article we propose the GEYSERS project approach for Future Internet based on provisioning full infrastructures as a service by using IT and transport network resource virtualization. An overview of the project's architecture is provided that shows the layering scheme empowering the definition of Virtual Infrastructure service. The Logical Infrastructure Composition Layer in the architecture allows for operator-tailored planning of infrastructures, which also allows for a dynamic re-planning of the infrastructure depending on service needs. The rest of the article elaborates on the concept, characteristics and variants for modifying Virtual Infrastructures, as well as their implications. © 2012 ICST Institute for Computer Science, Social Informatics and Telecommunications Engineering.
