1 IP Services over an ICN The Internet as our ICN use case Dirk Trossen, InterDigital Europe IRTF ICNRG Meeting © 2015 InterDigital, Inc. All Rights Reserved.

2 A Hypothesis-Driven ICN Story Our starting point: The Internet is the killer app for ICN Make this work and you have a strong starting point for ICN Our hypothesis: IP over ICN has the potential to run IP services better than in standard IP networks Show that this is true and you have a strong reason for deploy ICN! Our approach: Design, build, trial and test Clear set of quantitative and qualitative statements regarding our hypothesis © 2015 InterDigital, Inc. All Rights Reserved.

3 Expected Benefits Coincidental multicast Re-introduce multicast in the light of proliferating HTTP unicast Direct path mobility No more anchor points Fast surrogate support Evolution of CDNs but NO universal caching! Fast node/link resilience Delay-constrained insertion of surrogates Important for current 5G discussions Democratization of CDNs Content provisioning by smaller content providers (no need for large-scale CDNs) © 2015 InterDigital, Inc.

7 From a Use Case to a Working, Deployable System Standardization Needs Various building blocks System architecture (possibly more the space for ETSI or others?) Namespaces for protocol abstractions Governing of root scopes (assignment? Scopes of scopes?) Interfaces/protocols Protocol encapsulations Lightweight transport (for HTTP abstraction) ICN-internal interfaces (particularly for highly delay-optimized versions) SB interfaces, particularly to SDN Main issue: IPoverICN proposition itself Use case that is valid to include in wider ICNRG discussionsOR Warranting an own work area? © 2015 InterDigital, Inc.

8 Summary ICN is an ongoing evolution We have moved from true endpoint communication to content oriented communication a long time ago We believe that the current Internet is the ultimate use case for ICN Make it work – great! Make it work better – potential for ICN deployment! We are dedicated to making IP/HTTP over ICN work KPI-driven approach (with trials) to quantify the improvement part © 2015 InterDigital, Inc.
