Next Steps in Path Computation Element (PCE) Architectures: From Software Defined Concepts to Standards, Interoperability and Deployment

CSA FP7 ICT Call 11Objective ICT-2013.1.1: Future Networks

Francesco, Ramon, AdrianMay 13, 2015

Workshop "Path Computation Element and beyond:

innovating control and management functions towards fully reconfigurable

software-centric networks"

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

What is a PCE?

• PCE – Path Computation Element - The google maps of networks• http://ict-pace.net/index.php/pce-handbook/ & PCE Primer

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”

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)
