2. Table of Contents Background Why I am in this conference Purpose of this presentation CDN & CDNetworks CDN – What it is CDN – Who utilizes it CDN – How it works CDN – What it delivers and accelerates Huge bandwidth saving in middle-mile CDN – Who is providing CDN CDN cache for only its customer websites CDNetworks – History and Solutions CDNetworks – Global presence CDN Deployment CDN POP deployment POP deployment approach Example of deployment: South East Asia Data Center Selection Peering and IP transit POP deployment step Challenge and Experience With Tier 1 ISP No local path between local ISPs For Data Center For IXP Device sourcing and delivery Censorship Africa and CDNetworks Internet in Africa CDNetworks in Africa
3. Why I am in this conference Do you know CDNetworks? Do you believe my understating about this area is good enough? Internet Solutions JINX Optinet/MWEB SEACOM
4. Purpose of this presentation To tell you What CDNetworks is What CDN is What a CDN player experienced To hear from you User and ISP environment Hottopic in this community Your need from CDN players For friends
5. CDN – What it is Internet vs. CDN ? Content delivery network Delivery Internet contents from origins to the end-users Faster and more stable for end-users Less load and more burst for origins Any type of web content: text, image, video, and dynamic contents Less cost CDN customer CDN player End-users Origin www.foo.com CDN Content delivery network Over Internet End users
6. CDN – Who utilizes it Anyone who wants to deliver its content to the end-users Cost saving Quick provisioning time for content distribution Focus on the core business Improving the end-user experience Delivering the content quickly to the users Completing the transaction in shorter period
7. CDN – How it works Locating the contents closer to the end-users DNS delegation into CDN edges from the origin Component – Origin, Origin DNS, CDN DNS, CDN edge, User DNS, User Domain resolution and delegation 1st hit Following hit Query Response CNAME Origin DNS CDN DNS User DNS 1st 1st origin CDN edge Local End-users Internet Following hit
8. CDN – What it delivers and accelerates Delivering any web content Cache-able object Non cache-able object Accelerating Last-mile acceleration : Edge to the end-users Middle-mile acceleration: Origin to Edge Last Mile Middle mile origin CDN edge Local End-users Internet
9. Huge bandwidth saving in middle-mile Huge bandwidth saving in middle-mile 80% ~ 90% saving in general Cache-able content: 90% saving non cache-able content: 0% saving origin Local End-users Internet origin CDN edge Local End-users Internet
10. Huge bandwidth saving in middle-mile Last-mile traffic Middle-mile traffic
11. Less Load, Faster, Consistent Content Acceleration TrafficReduction:90%+ Peaktrafficofcontentserverisreducedto1/10oforiginaltraffic. CAPEXofCPswillbereduced.

12. CDN – Who is providing CDN CDN players Pure CDN players Telecom players Hosting players Examples CDNetworks, Akamai, Chinacache, Cloudflare, Level3, Limelight, TATA(Bitgravity), Verizon(Edgecast), and more
13. CDN cache for only its customer websites Cache system in ISP caches all websites Bandwidth saving Operational overhead Not scalable eventually and complex Cache of CDN players caches only its customer websites CNAME www.xabc.com www.xabc.com.cdnplayer1.com CNAME www.xbcd.com www.bcd.com.cdnplayer2.com CNAME www.xcde.com www.bcd.com.cdnplayer3.com $dig www.cdnetworks.com |grep CNAME www.cdnetworks.com. 285 IN CNAME www.cdnetworks.com.cdngs.net.
14. CDNetworks Overview Business Established Founded in 2000 with 13 year history, global CDN after 2007 Global Positioning One of the global pure CDN players $120M+ global sales revenue Financial Stability 350+ employees worldwide : Offices in US, UK, Korea, Japanand China Employees 1300+ customers - and growing, worldwide Customers Core Focus Accelerating critical enterprise applications and extending the global reach of our customers Network Deployment Global including China, Russia, Australia, Middle East and South America
15. CDNetworks – Global presence 40+ countries and 90+ cities
16. CDN POP deployment Different per CDN player Different according to the environment Sourcing the co-location space for CDN devices Sourcing the int’l Internet bandwidth to reach Origins Sourcing the local and regional Internet bandwidth CDN edges Int’l bandwidth Local bandwidth origin Internet Data Center Local ISP Local End-users
17. POP deployment approach Optimized location End-user Traffic Int’l bandwidth Utilize IXP Cooperate with local ISP Carrier neutral data center Closer to end users local coverage : high priority global coverage : mid priority Regional coverage : nice to have KDDI JINX Verizon HKIX Level3 LINX GTT Verizon DECIX Telia AMSIX Equinix SEACOM Telehouse MWEB Interxion IS Telecity MTN
18. Example of deployment: South East Asia CN TW IN Hong Kong VN TH PH MY Singapore ID
19. Data Center Selection Stable, Secure, easy for remote operation Having major ON-NET ISPs Hosting IXP with enough traffic
20. Peering and IP transit the peering policy OPEN Peering is preferred than IP transit Locating CDN edges inside ISP for that ISP coverage
21. POP deployment step Identify the traffic destination Select the POP type Peering POP : covering a specific ISP or area Transit POP : covering neighbor area Contact with data center players and ISP Check the device sourcing and delivery Make the agreement with data center and ISP Ship/source the devices to the data center Install the devices by on-site or RHS Difficulties are Finding right IDC and ISP Sourcing and shipping the devices Variable installation period per ISP Regulation
22. Challenges New Player and Incumbent : David vs Goliath Price and feature Cost vs Quality Closer to end users
23. With Tier 1 ISP Global Tier 1 ISP : no peering Regional Tier 1 ISP: lowering chance to peer with them Domestic Tier 1 ISP: lowering chance to peer with them ISP who is doing CDN service is trying to protect its home ground from other CDN players
24. No local path between local ISPs Example - Tele**ica Argentina Tele**m Argentina CDN player needs to deploy POP per ISP CDN player needs to have the circuits from both
25. For Data Center and IXP In US/EU, there are many choices of data center Carrier neutral, many on-net ISPs, IX and enough traffic In other regions, the optimal choice is limited.
26. Device sourcing and delivery In some country, the regulation forces No local entity, no device operation In some country, the device delivery from outside to inside takes long and it is painful procedure 8 months being hold in the custom
27. Censorship China Domain registration Blocking by great-firewall
