    • Multilink solutions in heterogeneous networks for increased capacity and robustness Terje Tjelta, Telenor, and Viktor S W Eide, Lividi• Results from the Celtic project MARCH 2007-2011 “Multilink architecture for multiplay services (MARCH)”• Main objective Significantly lower the cost of converged broadband service delivery by establishing scalable multilink network architectures• Presentation outline 1. Main results in the area of multilink economics, technology and network architecture 2. Multilink demonstration Verdikt 2012, Gardermoen 26 April 2011 1 URL: http://projects.celtic-initiative.org/MARCH/march/
    • AcknowledgementCeltic project MARCH International partnersMARCH Norwegian participants Project coordinator, and contributor to all project parts Multilink network architecture and live demonstrations Business and economics Research for Telenor on multilink network efficiencyMARCH received funding from Verdikt 2012, Gardermoen 26 April 2011 2 URL: http://projects.celtic-initiative.org/MARCH/march/
    • What is multilink?Multilink access allows simultaneous traffic for one singleapplication or several applications over two or morenetworks or links, such as mobile plus hot-spot, eitheroffloading entire application flows or split and merge flows or Benefits • increased throughput • increased reliability • improved service continuity • higher network Verdikt 2012, Gardermoen resources utilisation 26 April 2011 3 URL: http://projects.celtic-initiative.org/MARCH/march/
    • Three main results1. Broadband access market and economics2. Multilink network techniques and architectures3. Multilink network demonstrated Verdikt 2012, Gardermoen 26 April 2011 4 URL: http://projects.celtic-initiative.org/MARCH/march/
    • Broadband access market trends• Smart phones and other terminals keep pushing technical limits• Mobile data traffic doubles quickly, may be a year or so• The result is an explosive exponential traffic growth• Operators must invest in higher capacity networks, or use pricing to keep the growth at a manageable level Western Europe busy hour traffic Mobile data 16 times higher in 2015 compared to 2009 Relative to larger fixed data Traffic the ratio reduces to 6 in 2015 compared to 19 in 2009 2011 2012 2013 2014 2015 2016 Verdikt 2012, Gardermoen Year 26 April 2011 5 URL: http://projects.celtic-initiative.org/MARCH/march/
    • Business case: operator providing broadband access over 3G and Wi-FI access Business case assumptionsCustomers with multilink terminalsuse multilink transparentlycontrolled by the operatorIncreased revenue due to morecustomers (2-5%) in the samenetworkInvests in gateway and terminalsoftwarePopulation of 5 000 000 and amobile terminal penetration of 90%.20% of the terminals can supportmore than one network interface inYear 0, with an increase of 5-20%the first years.This business case shows a positivecash flow already in year 1.

    • Multipath gateway and over-the-topservices• Business opportunities, e.g., offered by a multilink service provider (ML-SP / Broker) o Live event video distribution; Surveillance video  Multiple markets; From large broadcasters to “prosumers” o Higher resolution video streaming o Person-to-person communication, video-conferencing• Mobile network operator may offer assured service quality to ML-SP o GSMA OneAPI o Multilink as a part of mobile broadband offerings Verdikt 2012, Gardermoen 26 April 2011 10

    • Multilink demonstration:• Robust and resilient video conference over multiple access networks (2011) o Multilink using available 3G and Wi-Fi networks o Demonstration shown by Lividi• Live video from ichthyosaur excavations at Svalbard (2010) Verdikt 2012, Gardermoen 26 April 2011 12 URL: http://projects.celtic-initiative.org/MARCH/march/
    • Real-time adaptive multilink streaming forvideo conference and remote operationsApplication requirements• Low delay o Limited buffering o No retransmission• Some of the data is more important that other, e.g.: o Good audio more important than good video o In scalable video (H.264/SVC) base-layer is more important than extension layer Verdikt 2012, Gardermoen 26 April 2011 13 URL: http://projects.celtic-initiative.org/MARCH/march/
