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)

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

Current PCD Listings Demographics of the Peering Contact Database

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

Preliminary Findings Some Peering Contacts are more than 2 Peering Coordinators out of date Discovered best practices of Exchange Point Operators Web Sites Many don’t have participants lists Highly variable types of info at exchanges European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

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

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

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

Large Global Network Provider 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

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

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

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

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?
