A PCE-based architecture for the management of virtualized infrastructures
08 October 2014
The emerging Network Function Virtualization paradigm (NFV) is a disruptive change that creates new business opportunities for vendors and carriers. By exploiting virtualization technologies, it allows the dynamic creation of logically isolated infrastructures over abstracted physical networks. To be able to offer Virtualized Services efficiently, service providers need a new class of Management systems able to manage and orchestrate both network and IT virtualized resources. In this paper, we propose an enhanced network Control Plane, based on the standard Path Computation Element (PCE) architecture, which is able to jointly make network routing and IT server provisioning decisions and that can be used in an NFV environment.
