1. Next Steps in Path Computation Element (PCE) Architectures: From Software Defined Concepts to Standards, Interoperability and Deployment CSA FP7 ICT Call 11 Objective ICT-2013.1.1: Future Networks Francesco, Ramon, Adrian May 13, 2015 Workshop "Path Computation Element and beyond: innovating control and management functions towards fully reconfigurable software-centric networks"

2. PACE http://ict-pace.net FP7 project (Call 11) Coordination and Support Action (CSA. GA no. 619712) 2013/11/01 – 2015/10/31 Focusing on research, development and standards in the broad area of Path Computation Element (PCE)- based architectures PACE is an open forum for ideas exchange about current and future uses of PCE aimed to bring out radical new proposals and to consolidate existing research. Resources Open source portal with PCE open source software and documentation repository, Education and dissemination of PCE concepts (PCE primers & tutorials) Papers, knowledge base, outreach Development and applicability of new uses of PCE Including SDN and NFV through support of ABNO Standardization leadership

4. What is a PCE? PCE – Path Computation Element - The google maps of networks http://ict-pace.net/index.php/pce-handbook/ & PCE Primer http://ict-pace.net/index.php/pce-handbook/ Request Endpoints Constraints Traffic Engineering Database Explicit Route (path) Total Path Cost / Metric “An entity (component, application or network node) that is capable of computing a network path or route based on a network graph (TED) and applying computational constraints”

5. What is a PCE? (2) The PCE was invented for a very specific reason: Aimed to solve multi- domain computation, Find an a path across domains Growth: Multi-domain & multi-layer networks (IP over optical) As a functional component of SDN architecture … In PACE, we see PCE as a widely applicable tool in the areas of: Core packet Internet Mobile backhaul networks Content Distribution Networks (CDN) Next generation optical transport networks Sensor networks, wireless mesh and Internet of Things (IoT)
