  11. Why Telco CDN interconnection ? • For the QoS guarantee of inter ISP Content Delivery, we needTelco CDN interconnection. • Economy of scale for content exchange market • No economy of scale in Walled Garden content delivery market, but Big economy of scale in Open content exchange market • Big economy of scale for ‘Not only CP/OTT, but also for micro CP’ • Revenue sharing between Telcos from content exchange • Dumb Pipe Best Effort internet interconnection  Free of Charge status  ‘Traffic Increase, Revenue Decrease’ This miserable status keeps going! • With Telco CDN interconnection, we can make ‘Revenue Sharing and Traffic decrease of dumb pipe interconnection’. NTT Low Cost/ QoS guarantee ($) IX Content exchange($$$) Telco CDN Interconnection CP kt Telco CDN IX Economy of Scale IX ($) CT Revenue Sharing Vientiane, Lao People’s Democratic Republic, 30-31 July 2012

  12. Why Telco CDN interconnection ? • Current IX/Overseas traffic status • IX traffic ratio in TelcoBackbonekeep increasing (60%70% during last 5years) • No QoS guarantee for inter ISP Content Delivery in peak time Inter Telcotraffic Keeps increasing Telco2 Telco3 Others 60% 70% IX(ISP) IX IX IX IDC Congestion in peak time 32%24% IX TelcoBackbone Core Telco 1 • We can Reduce IX/Overseas traffic increase with Telco CDN interconnection and guarantee QoS for such Inter ISP Content Delivery service.

  15. Global Telco CDN interconnection issue (Network Neutrality issue] • Conflict between Level3(CDN provider) and Comcast • Level3 is making originally ‘free peering contract’ with Comcast for the Global CDN service and CDN traffic transmission. • After Netflix was changing their CDN provider from Akamai to Level3, Level3 CDN traffic is makingexplosive increase. It is making Big burden and Big Load to Comcast • So, Comcast is asking another Payment for that Traffic increase to Level3. But Level3 claim that they can’t pay from the FCC’s Open Internet Rule.  This is making Another type of Big issue of Network neutrality. • Charging issue of Content Delivery Inter ISPs  Time critical issue !
