  1. Peering Information: Some Data Points William B. Norton Co-Founder and Chief Technical Liaison Equinix, Inc.

  2. NSFNET to Post-NSFNET Era Internet Merit OarNet NyserNet NWNet • NSFNET (1987-1994) Regional Tech Meetings • Performance & Operations • Reporting & Coordination • Routing & Network Planning NEARNet BARRNet NSFNET Regional Regional Sesqui SDSC Regional NCAR OarNet Merit NWNet NyserNet ANS Privatization (1994-Now) North American Network Operators Group (NANOG) Meetings UUNet Sprint MCI Regional AT&T Regional Regional Regional Mom, C. No Internet Preso…

  3. Internet Statistics • 87.5% of all Internet statistics are made up. Source: I made it up. Source: I made it up

  4. My Job Now • Bad Jokes in Public Forums • Internet Operations Research • Present Findings in Forums • ITU – Rio de Janeiro • RIPE – Budapest • NANOG – Montreal, Eugene • ISPCon - * • IIR – London • Inet – Prague, Yokohama APRICOT – Manila, Singapore, Seoul, Kuala Lumpur INTAP - Tokyo IETF – Oslo FCC – Washington DC ITW – Seattle Cisco Forum, CLEC Expo, IWS2000 Tskuba, Etc. Audience…

  5. Internet Service Providers and Peering • 200 ISP Peering Coordinators • Terminology, strategies, • Process, thought pattern •  One of the Most Difficult Parts of Peering is Initiating Contact (who, how, initiating dialog)

  6. So, at Montreal NANOG • Peering BOF – presented white paper • Introduced “Peering Contact Database” • Only for Peering Coordinators • Toss in business card (w/AS#) All those in PCD get e-mailed updated PCD • 130 Peering Coordinators listed today • I evangelize the PCD during my talks

  7. Current PCD Listings • Demographics of the Peering Contact Database

  8. Survey 2001: Study of Global IX Populations • Surveyed All exchange points in the worldψ • Copied All participants information • Midway through 2000 2001 Combining contact info From multiple exchanges Gives a better view of Potential contact points Ψ Started with ep.net and expanded into other publicly available information

  9. Preliminary Findings • Some Peering Contacts are more than 2 Peering Coordinators out of date • Discovered best practices of Exchange Point Operators Web Sites • Many don’t have participants lists • Highly variable types of info at exchanges • European exchanges tend to be have better web sites for ISP Peering Coordinator usage

  10. Best Exchange Point Web Site in the World • Clearly understands the information needs of the ISP Peering Coordinator • Telcos • Names, sales contacts, phone #s and e-mail • Participating ISPs • Names, peering contacts, phone #’s and e-mail • Crisp Layout

  11. Recent additions to the “Internet Service Providers and Peering” White Paper Last Version 3 Stages of Peering: Selection of Peering Partners Initial Contact / Peering Negotiations Peering Implementation  Top 5 Reasons NOT to peer

  12. Transit $$$ Yahoo! Top 5 Reasons not to Peer 1) Already get Traffic for “free” (through existing peering relationships) Transit ISP EXODUS Peering $ AOL

  13. Top 5 Reasons not to Peer Huge investment in Int’s circuits, 100’s of routers and colo sites, Staff installs, peering negotiations, Millions of customers, etc. 2) Not True Peers • Traffic inequity • Scale inequity • Not even investments in infrastructure • Form: “I don’t want to haul your traffic around the globe” Large Global Network Provider Small Regional Player

  14. 3) Lack of Technical Competence Troubleshooting network problems takes longer when the other ISP NOC and engineers lack the technical expertise during an outage… Top 5 Reasons Not to Peer

  15. Top 5 Reasons Not to Peer 4) Transit Sales Preferred • We rather sell you transit…“Let me introduce you to our sales guys”

  16. 5) BGP is Tough “BGP? No ExpertiseNo measurements No Justification to hire expertsBGP?” Top 5 Reasons Not to Peer Simple Complex Conceptual Hurdle Conceptual Hurdle Primary Backup Transit Primary Backup Transit 6: personality

  17. Top 5 Reasons Not To Peer 5+ Personality Clashes: They don’t understand each other and they don’t like the interaction

  18. Thank you for coming: Main Points • Survey 2001 – Contact Info out of date • Peering Contact Database • Send e-mail to wbn@equinix.com to get listed • Resources Available to the Peering Coordinator Community…

  19. Resources: Internet Operations Research White Papers • “Interconnection Strategies for ISPs” • “Internet Service Providers and Peering” • “Peering: Cost Savings Strategies for ISPs”  draft • “Peering Simulation Game”  draft • “Build vs. Buy Internet Datacenter” draft • Send e-mail for the Peering Contact Database • Send e-mail to wbn@equinix.com

  20. White Paper: Interconnection Strategies for ISPs • Direct circuits replaced with: • OC-12 into Exchange • Fiber cross connects • Cost Drivers: • Big OC-12 Direct Circuit • Cheap Fiber Cross Connects • Aggregation Efficiency over OC-12 (2:1,3:1) • Rack Fees • Exchange Model Cost Formula: ExchangeModelCost=BigDirectCircuit()+(n-1)*x/2+RackFees() OC-12 $23,000/mo XC=$200/mo Rack=$1500/mo So does the Exchange-based model make sense?

  23. White Paper: The Peering Simulation Game

  24. White Paper: Build Vs. Buy Internet DataCenter • Modeling: • When does it make sense to build your own? • To Outsource? • Issues to consider • Economies of Scale? • Multiple Business Models
