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
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
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 2013 8 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
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

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

POINT: combining POINT: ip Over IcN- the better IP 3.5 Me European Commission H2020 Project (Jan 2015-Dec 2017 H2020-ICT 643990) 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
