Speakers Biography: Dr. Ravi Ravindran is a Senior Staff Researcher at Huawei. He has been conducting advanced telecommunications research for over 15 years. His current area of research focuses on Information-centric Networking and extends to Internet of Things , 5G, NFV and SDN. Specifically, his research focus has been on NSF-funded future Internet proposals such as NDN/CCN, Mobility First, and XIA , in collaboration with standard bodies (IETF/ITU) ,external research groups and academia. Prior to this role, he was part of the CTO office at Nortel, where he was part of the Advanced Technology Group focused on research areas like Control Plane Routing Protocols related to IP/(G)MPLS, Scheduling problems in 4G Wireless, and End-to-End QoE/QoS Engineering for Multimedia. Over the course of his research, he has been part of more than 10 granted patents and over 40 pending filings in various areas of networking technologies. He has over 30 technical publications in conferences and journals. Dr. Ravindran received his Ph.D. in Systems and Computer Engineering from Carleton University in Canada.

5G-ICN Architecture
5G Requirements Requirements have been set in [1] • Enable Service Centric Networking – Allow new Business Models – XaaS (Naas/SaaS/PaaS) – Not only Connectivity Services – Service Platform for Users and ASPs – Personalized and Contextualized • Low end-to-end Latency – 1-10ms depending on the application • High Capacity and Data Rate – >1000x Capacity, >10-100x Bandwidth • High Reliability – Security, Mobility, Disaster Scenarios • Heterogeneous Devices and Applications – Traditional and Emerging IoT (M2M)) [1] NGMN White Paper on 5G: https://www.ngmn.org/uploads/media/NGMN_5G_White_Paper_V1_0.pdf
How ICN Meets these Requirements ? • ICN provides a flexible Service-Centric Platform. – Build in Security/Mobility/Muticasting/Compute/Cache • Placement of Compute and Cache/Storage Anywhere – BS, Lamp Posts, Home Gateway, Routers, etc • ICN Provides Information (service/content/host) Packet Abstraction to process/store it anywhere. • Multiple Modes of Communication – D2D/P2MP/MP2MP • Name Based Networking MORE SECURE than Address Based Networking – Security/Context tightly binds to Identity (e.g. Mitigate DDOS) – Many Security risks due to Address Exposure [1] – Receiver oriented communication, Receiver Anonymity. • Scalable and Flexible Name Resolution System – Local and Global • Mobility via Caching and Late-Binding • Service Orchestration via dedicated ASP Controllers working over ICN Network Abstractions.
