2 Introduction 1 Introduction Information-Centric Networking and

3 Media streaming Introduction Traditional architecture: Client/server, Sender is web server hosted by originating company RTP/UDP/IP delivery model Current architecture: Custom media platforms, heterogeneous receivers Cloud based processing/delivery Content delivery networks Often HTTP/TCP based delivery Future architecture: Information Centric Networking??... a combination of the two? Information-Centric Networking and

4 Information awareness: Content natively recognized and processed Locate and Deliver based on WHAT not WHERE Offers a number of benefits: Content can be requested from any (valid) source Content storage/processing can be optimized with regards to network delivery parameters Delivery through the network can be optimized with respect to content requirements (e.g. delay, quality) Better content security and integrity Information-Centric Networking and

5 Information centric networking ICN projects Content centric networking (CCN), COMET, Named data networking (NDN), PURSUIT, SAIL,... (and starting now: POINT) PURSUIT EU FP7 Project, 30-month duration, Finished Feb Partners: Aalto-HIIT, AUEB, University of Cambridge, CERTH, CTVC, University of Essex, Ericsson, RWTH Clean slate approach, defines architecture but allows various implementations Example (reference) implementation: Blackadder Information-Centric Networking and

6 PURSUIT-ICN: Review Advanced Information Management Matching Supply with Demand Delivery from Publisher to Subscriber Multiple subscribers can receive content with native multicast Information-Centric Networking and

7 ICN architecture Introduction Rendezvous Pub. LID= Topology Manager 5 Packet switched using BF Data LID= FW LID= LID= FW FW Sub. LID= LID= FW Data Alternative path with different BF Information-Centric Networking and

8 Caching Introduction P P P S A content delivery network without all the nasty DNS redirection or application layer packet inspection as used in the current Internet. Information-Centric Networking and

9 Multilayer Testbed Introduction Information-Centric Networking and

10 Multilayer Testbed: Usage in ICN Research Routers connected by optical light-paths Light-paths can be configured using the PURSUIT pub/sub communication approach Utilised to demonstrate some of the traffic engineering functions in the PURSUIT-ICN network: QoS Information-Centric Networking and

11 ICN-TE Demo: Information-Centric Networking and

12 ICN-TE Demo: Information-Centric Networking and

13 ICN-TE Demo: Information-Centric Networking and

14 ICN-TE Demo: QoS Information-Centric Networking and

15 ICN-TE Demo: QoS Information-Centric Networking and

16 Software defined networking Openflow Opens up existing switches for custom use existing switch hardware essentially similar between vendors controlling software opened up to a standard open interface Researchers (and increasingly operators) can define their own switching rules: switch based on low level addresses (MAC) switch based on packet headers highly flexible rules requires a semi-centralised controller Information-Centric Networking and

17 Example media application of SDN Live migration of cloud based transcoders for ultra-high definition video delivery Migrated Transcoder 4K Video Stream Original Transcoder 4K Requires optimisation of placement and switching times... Information-Centric Networking and

18 POINT: combining POINT: ip Over IcN- the better IP 3.5 Me European Commission H2020 Project (Jan 2015-Dec 2017 H2020-ICT ) 9 partners: AALTO (Finland), AUEB (Greece), CTVC Ltd (UK), ELL-i (Finland), InterDigital Europe Ltd (UK), Intracom (Greece), PRIMTEL (Cyprus), RWTH (Germany), University of Essex (UK). Combines ICN work from PURSUIT with SDN Aims to overcome problems of other ICN projects (including PURSUIT): allows clients to use IP with no changes (other than standard settings) integrates with the next-generation of operator networks moves towards first deployment trials of ICN Information-Centric Networking and
