Vision of the Future

• Our second open discussion

• Clearly takes input from the earlier session

• Anything is possible– What might a PCE-enabled future look like?

• Two threads– If we advance our current uses of PCE, what might we

achieve?– If we expand PCE’s applicability, where might we end up?

I’m Percy – How can I help?

A Long List of Potential Ideas• IP-Over-Flexigrid Networks• Ever more SDN ideas• NFV• Service Function Chaining• IP Fast Reroute • MPLS Source Routing (Segment routing)• Multi-segment Pseudowires• Power-aware networking• Internet of Things• Deterministic wireless networking• Managed Ethernet (e.g. TRILL)• Integrated IP/Ethernet (DetNet)• Whitespace• Trust routers• Application space routing (SIP, content, …)• Web-based PCE• iPhone Application• 5G

Let your imagination run wild!

• What problems are similar to those we have solved?– Navigating network graphs– Integrating network graphs from different technologies

or administrations– Applying constraints to path computation– Computing sets of paths

• Possible topics– Real maps (Google maps etc., traveling salesman)– Social networking (marketing, advertising)– Physical service distribution (electricity, water, sewerage)

Whiteboard for Your IdeasYour ideas here…• Traffic infrastructure– Bus, train scheduling

• Integrate with traffic infrastructure

– Emergency services– Autonomous vehicles

• Distribution and integration of paths

• Low orbit satellite• Natural language interface to PCE• Reshaping a (mobile) network– Prediction and instruction

• Big Data
