All Rights Reserved. ? Moving 5G from Research Concepts to Industrial Reality SDN and Wireless NFV in Mobile Edge ICN and IP Getting the best of Both Worlds 6 Information Centric Networking: An inevitable destination? What is ICN? ? ICN defines a paradigm shift in networking away from host to host communication ? ICN focuses on content and name based addressing concepts ? Brings publish-subscribe model paradigms to core networking principles Key Trends Driving to ICN Future ? Today?s internet would simply not work without content caching moving deeper into network ? 5G latency challenges will push this content literally to the edge ? Married with growing trend of increasingly programmable networks = ICN Perfect storm ? 2015 InterDigital, Inc. All Rights Reserved. Deeper and deeper distribution of content in the network through caching 7 Two Traditional Paths: Neither Path Ideal To Market Uptake ? 2015 InterDigital, Inc. All Rights Reserved. + Exploit developments for SW-based networks + Evolution path along existing systems + Preserve main relationships - Potential for inefficient solutions - Preserve problems of current IP architecture - Hamper new usages, e.g., in IoT space 2. Follow slow IP evolution 1. Follow the pure ICN path - Huge standardization challenges - Challenges to align value chain - Backward compatibility challenges + Better utilization through native multicast + Better privacy for content consumers + Better resilience (compared to path resilience) InterDigital vision sees a hybrid approach that brings best of both + Better performance through native multicast + Better privacy + Better resilience + Exploit developments for software-based networks + Evolution path along existing systems + Preserve main relationships - Need technology solutions and IP building blocks to turn into products Focus of InterDigital Efforts One of our H2020 ICN Project Activities: Project POINT It looks like IP, smells like IP, but it runs better with ?our?
