Next Steps in Path Computation Element (PCE) Architectures: From Software Defined Concepts to Standards, Interoperability and Deployment CSA FP7 ICT Call 11 Objective ICT : Future Networks Oct 23, 2013 An Innovation Kitchen ~ A Think Tank for All

What motivates PACE? From academic research to innovations – The application driven networks (ADN) and software defined networks (SDN) recent examples of rapid transitions to innovation Indispensable industrial-academic alliances – Our research and industrial community is energized by the pursuit of ADN, SDN, and other and related innovations Openness and democratization of innovation – Open formats/open interfaces/user-driven programmability & democratizations of applications and content distribution IETF Path Computation Element (PCE) – A ripe standard and a prime example of a software defined network artefact & a tool to innovate in future networks

New Grounds: PCE and Wireless WLAN and Mesh – More about ensuring any-to-any reachability and providing load balancing than path computation per se – Topology data base, automated network planning, handling of TE parameters, etc. Wireless cellular – Cell infrastructure planning with “what if” capabilities considering traffic growth, mast failure, interference, and mast installation – PCE for mobile backhaul helps data – Can PCE help with planning of cell hand-off and manage policies for the same? Wireless sensor networks and broadcast – PCE compliments RPL in sensor networks – PCE as whitespace data base server?

Current SDN Specific Challenges Open Networking Foundation (ONF) – Design control systems and well-defined interfaces with external (non-ONF) functions, representing a not-to-be-missed opportunity for the third-party network control and management systems, such as PCE Network Functions Virtualization (NFV) – ETSI initiative leveraging virtualization concepts, with the growing role of PCE-like concepts Application-based Network Operations (ABNO) – An architecture proposed, developed and led within the IETF by leading members of our consortium – uses a variety of PCE-based tools and techniques.

PACE Innovation Kitchen Innovate in system design, applications and algorithms in a variety of technologies, including: – Core packet Internet – Mobile backhaul networks – Cloud computing networks – Content Distribution Networks (CDN) – Next generation optical transport networks – Wireless sensor and mesh networks, Internet of Things (IoT) Promote innovation through third party network management applications and openness – Consolidate the PCE open source community

PACE: A Think Tank for All Research, development and standards – Clouds, Radio, Fiber, Internet of Things, Future Internet – A coordination action with the goal to concentrate and rapidly push forward PCE research efforts, development activities, and standardization Open source portal – Call for Cooperation – A portal, open source software and documentation repository Open forum for ideas exchange – Working Group creation – An open exchange of ideas about current and future uses of PCE aimed to bring out radical new ideas and to consolidate existing research Commitment to innovation – Workshops with published findings and recommendations – Bringing together thought leaders from Europe and around the world to investigate the stretch-potential for PCE in future networks
