Peering 101a

  1. 1. Speaker: Fred Cannone, Director of Sales and Marketing<br />With commentary by Akio Sugeno, Vice President of Internet Engineering, Operations, and Business Development<br />
  2. 2. Peering 101: Agenda<br />TELEHOUSE Introductions<br />Purpose of this webinar<br />What is the Internet?<br />What is Internet traffic mean?<br />How do ISPS connect to each other?<br />What are Internet Routes & How do they Work?<br />Transit vs. Peering<br />What a well architected network connects?<br />What is Peering and its Benefits?<br />Peering Types?<br />
  3. 3. Peering 101: Purpose<br /><ul><li>Educate
  4. 4. Introduce this valuable network resource
  5. 5. keep folks informed about this valuable resource
  6. 6. Utilization
  7. 7. Not just for Large ISPs
  8. 8. Resources</li></li></ul><li>Who is TELEHOUSE?<br />4<br /><ul><li>Parent company, KDDI.
  9. 9. Consolidated revenue $34B.
  10. 10. Total IT Solution – NYIIX 1996 / LAIIX 1998</li></ul>Copyright Telehouse America 2010<br />
  11. 11. Peering 101: What is the Internet?<br />5<br /><ul><li>NOT a single Network!
  12. 12. NO one owns it.
  13. 13. NO central organization to admin or monitor
  14. 14. Over 36,000 ISPs – autonomous networks
  15. 15. Internet - multiple autonomous networks Somehow connected and make work !!!</li></ul>Copyright Telehouse America 2010<br />
  16. 16. What is Internet Traffic?<br />6<br />BGP<br />Border Gateway Protocol<br />I’m on ISP-B<br />Mom on ISP-A<br />e.g.<br />e.g.<br />Exchange:<br />Internet Traffic<br />between two different ISPs<br />(or Networks)<br />Copyright Telehouse America 2010<br />
  17. 17. How do ISPs connect to each other?<br />7<br /><ul><li>Transitprovides full global Internet routes* or access to all IP addresses
  18. 18. Peeringprovides partial Internet routes* or access to limited number of IP addresses.</li></ul> costs money. <br /> VS.<br />Transit<br />Peering<br />(*) Routes are basically addresses<br />Copyright Telehouse America 2010<br />
  19. 19. What are Internet routes?<br /><ul><li>Each ISP has: -Code Name (ASN) Autonomous System Number -owns routes or addresses - similar to ZIP code / street address relationship.
  20. 20. IP Address space e.g. (254 addresses)</li></ul>ZIP<br />12345<br />ISP-A<br />ASN: 12345<br />10 Main St.<br />25 Wood Ave.<br /><br /><br />8<br />Copyright Telehouse America 2010<br />
  21. 21. How do Internet routes work? (Inbound)<br />To Receive Traffic…<br /><ul><li>An ISP has to announce (BGP) its routes (or addresses) to the Internet in order to receive the traffic destined to the route.</li></ul>ISP-A<br />I have the route.<br />Send traffic to that route<br />to me!<br />Internet<br /> Announces<br />BGP<br />e.g.<br />9<br />Copyright Telehouse America 2010<br />
  22. 22. How do Internet routes work? (outbound)<br />10<br />To Send Traffic…<br /><ul><li>ISP must have full routes announced (BGP) to the Internet and keep them in its routing table to ensure global reachability to its customers.
  23. 23. Its routers make a routing decision based on its routing table. </li></ul>Where is the destination route in my routing table?<br />Send the traffic to port 1, slot 2, on NY#1 router<br />Found it!<br />Copyright Telehouse America 2010<br />
  24. 24. Transit vs. Peering<br />11<br />The best network architecture:<br /><ul><li>Combines transit and peering</li></ul>Copyright Telehouse America 2010<br />
  25. 25. How an ISP/YOU, well architected network, connects to the Internet<br />12<br /><ul><li>Minimize (bps) Transit & Max Peering traffic</li></ul>Standard ISP architecture:<br />Partial Routes to/from “The” ISP (*) A, B, C, …. Z<br />Full Routes <br />B<br />A<br />ISP/You<br />Transit<br />Peering<br />Tier 1 ISP<br />D<br />C<br />E<br />Z<br />Pay $$$ <br />Free<br />Large (Tier 1)<br />Provider(s) <br />(*) When peering with ISP-A, you can get routes from/to ISP-A only<br />(partial routes)<br />Regional or local providers <br />Copyright Telehouse America 2010<br />
  26. 26. What is Peering?<br />Peering is simply the settlement free exchange of internet traffic. <br />
  27. 27. Benefits? ….saves money<br />Transit costs money….Peering is FREE!<br />
  28. 28. WHY Peer?<br />15<br /><ul><li>Free – averages down Transit costs
  29. 29. Routing options
  30. 30. Less latency</li></ul>A<br />B<br />ISP-C is multiple ISPs away<br />ISP/<br />YOU<br />Z<br />Tier 1 ISP<br />Transit<br />E<br />Source<br />Peering<br />C<br />ISP-C is close<br />Destinations<br />Copyright Telehouse America 2010<br />
  31. 31. Who Peers & Who Benefits?<br /><ul><li>Large ISP’s/businesses can more readily </li></ul> access niche, regional traffic.<br /><ul><li>Small to medium size (traffic) businesses </li></ul>YOU<br />can access the mainstream traffic, as well as <br /> niche, regional traffic too.<br />
  32. 32. Benefits? ….increased network reliability<br /><ul><li>Improved Connectivity: Meeting at the Layer2 switch
  33. 33. Averaging down of bandwidth costs: Exchange traffic directly and avoid travel over paid bandwidth
  34. 34. A Plethora of Routing options: diversity of routes and traffic</li></ul>No longer restricted to just ISP’s and Telecom Providers!<br />
  35. 35. Peering Types<br />18<br />Bi-Directional: Exchange the same amount of traffic<br />Uni-Directional: Content heavy to Eye-ball heavy<br />Copyright Telehouse America 2010<br />
  36. 36. Peering Types<br />19<br />Bilateral: Selective based on business decision<br />Multilateral: Easy peering with open peering policy<br />via Route Servers<br />1 ISP<br />Multiple ISPs<br />Copyright Telehouse America 2010<br />
  37. 37. Peering Types<br />20<br /><ul><li>Over 300 known Internet Exchange Points (IX) in the world.
  38. 38. Operated by profit or non-profit organizations.
  39. 39. Carrier neutrality is a key to success.</li></ul>Copyright Telehouse America 2010<br />
  40. 40. Public IX Platform<br />21<br /><ul><li>Layer 2 Switch platform (today’s mainstream)
  41. 41. Peer on the same broadcast domain
  42. 42. Optional route servers for multilateral peering</li></ul>Copyright Telehouse America 2010<br />
  43. 43. Public IX Platform<br />22<br /><ul><li>L2 Switch platform has been proven.</li></ul> - Peering protocol (BGP) requires L2<br /> - Up to 10G Port Wire-speed guaranteed<br />- Optional jumbo frame for optimal MTU<br />- Optional VLAN for private peering<br /> - Readily Scalable to higher speed <br /> (40/100G)<br />Copyright Telehouse America 2010<br />
  44. 44. Public IX Operation Issues<br />23<br /><ul><li>Not so secure (on the same b’cast domain)</li></ul>- Your traffic may be affected - VLAN is not practical - Limited to 4,094 VLANs (e.g. 120 x 120 / 2 = 7,200!)<br /> - Difficult to manage<br />Copyright Telehouse America 2010<br />
  45. 45. Public IX Operation Issues<br />24<br /><ul><li>No MTU Optimization</li></ul> - Low speed Ethernet use MTU 1,500 - Higher speed Ethernet opts for > 1,500 - There is no agreeable MTU size - Still use MTU 1,500 for this reason<br />Copyright Telehouse America 2010<br />
  46. 46. Public IX Operation Issues<br />25<br /><ul><li>No Traffic data per peer</li></ul>- ISP wants to know traffic per peer<br />- SNMP only shows traffic per physical port<br />- sFlow? But it is on sampling basis.<br />Copyright Telehouse America 2010<br />
  47. 47. Public IX Operation Issues<br />26<br /><ul><li>No Traffic Engineering</li></ul>- If IX’s topology is triangle, traffic flows only via one particular path due to STP.<br /> - Traffic does not take the shortest path. <br />Copyright Telehouse America 2010<br />
  48. 48. Future Developments<br />27<br /><ul><li>MPLS Based IX (proposed at NANOG 2002)</li></ul>- MPLX router based IX (not L2 switches)<br /><ul><li>Benefits</li></ul>Secure tunnel per peering session<br />Optimal MTU per peer<br />SNMP MIB per tunnel for traffic analysis<br />Traffic Engineering (via RSVP)<br />Copyright Telehouse America 2010<br />
