Policies for “Network Fit for Purpose”: essential infrastructures: energy, transport, water, networks. Stages of broadband debate: availability/coverage (supply), adoption (demand), speed/price, quality. “How do I compare? How do I improve?” Governments are asking how to compare?
Cisco’s Visual Networking Index: developing a model to look at real network traffic. Findings: global IP traffic growth growing 6 fold between 2006-2012, moving zetabytes of data around. For consumers, video will account for 50% of traffic (traditional TV is only a portion, includes video interactive). Mobile networks: video will be 64% of traffic by 2013. Today’s networks will not support that, and most networks are fixed, which has HUGE implications for investments needed in networks. Traffic will be unpredictable: 50M vs 4M users downloading same PB/month. Multiple dimensions of broadband: not just speed, but also latency, jitter, more, that will differently affect applications and uses of networks. Will need to be future-proof and extensible.
Broadband Quality Score (study): changing quality requirements. Yesterday/today: Facebook, YouTube. Tomorrow: visual networking, high-definition networking, large file sharing has greater base requirements. Study developed an index to calculate broadband quality scores. In 2008: Japanese network was only one that supports tomorrow’s needs. US network barely met today’s needs. In 2009, significant global improvement over that year but still significant problems.
Broadband leadership redefined: it’s not just quality, it’s about usage. Quality leaders, penetration leaders, others catching up. Chart: upper right corner are broadband leaders (S Korea, Japan, Hong Kong, northern European clusters). Emerging markets trying to leapfrog. Significant improvements year over year: everyone gets it.
Demand and usage is driving change. User demand coming from two-way video, collaboration, education, health care. Applications: differentiated services, huge implications for networks (investment, architecture), managing for differentiateion, implications for content and service providers.
