Dealing with Internet Congestion:

  1. 1. Dealing with Internet Congestion: Two Solutions “ Energizing the Internet” Michael Weaver Bucknell University
  2. 2. About Bucknell <ul><li>Private Liberal Arts University </li></ul><ul><li>Primarily undergraduate </li></ul><ul><ul><li>3,250 undergraduates </li></ul></ul><ul><ul><li>200 graduate students </li></ul></ul><ul><li>Primarily residential </li></ul><ul><li>Located in central Pennsylvania </li></ul>
  3. 3. In the wake of the Spring, 2000 Napster explosion…
  4. 6. <ul><li>The cost of our Internet connection keeps going down. Soon it will be cheap enough that we won’t need to worry about bandwidth consumption! </li></ul>Myth 1
  5. 7. Something to Ponder! If audio from Napster causes this much trouble, what will happen as video becomes more widely available?
  6. 8. What’s the Potential? Do the Math! <ul><li>2800 computers in Resnet </li></ul><ul><li>100Mbits/sec connection for each computer </li></ul><ul><li>2800 * 100Mbits/sec = 280,000 Mbits/sec </li></ul><ul><li>Our capacity to consume content: roughly 31,000 times our current Internet connection to Resnet! </li></ul>
  7. 9. More realistically <ul><li>There probably aren’t too many 100Mbits/sec streams out there. </li></ul><ul><li>But there are lots of 1Mbit/sec streams </li></ul><ul><li>2800 * 1 Mbit/sec = 310 times our current Internet connection. </li></ul>
  8. 10. Something to ponder! Is the price of our Internet connection going to come down enough that we can increase it’s capacity 310 times?
  9. 11. Myth 2 <ul><li>We need to protect our technology resources for the “Academic Mission” of the University. </li></ul>
  10. 12. Something to ponder! <ul><li>How much of your current network activity is directly related to the “Academic Mission” of your University? </li></ul>Email? Web browsing? Other communications (IM, for example)?
  11. 13. Something to ponder! <ul><li>Was your decision to implement Resnet an “Academic” decision? </li></ul>Was your Admissions Office involved in that decision?
  12. 14. Something to ponder! <ul><li>How many of your students have a high speed connection (like DSL) at home? </li></ul>Do you expect that number to grow? Is this “home” use strictly academic, or does it include recreation and entertainment? Does it (or will it) include audio and video?
  13. 15. Something to ponder! <ul><li>These are lifestyle changes! </li></ul>They are here to stay! Our students will expect the same capabilities in their dorm rooms that they have at home!
  14. 16. Something to ponder! <ul><li>To what extent do these lifestyle changes enable technology for academic use? </li></ul>Was email a useful academic tool before it was part of our lifestyle? Web browsing? Etc…
  15. 17. “Academic Mission” Restated <ul><li>We must recognize the lifestyle demands on our technology resources, </li></ul><ul><li>finding ways to accommodate them, </li></ul><ul><li>without jeopardizing the academic needs for those same resources. </li></ul>
  16. 19. Launchcast <ul><li>Internet radio station with a twist </li></ul><ul><ul><ul><li>Users can “personalize” their radio station </li></ul></ul></ul>
  17. 20. My thinking <ul><li>If we could put Launchcast content in the Bucknell network: </li></ul><ul><ul><li>We would provide students with a legal alternative to Napster </li></ul></ul><ul><ul><li>We could reduce the traffic on our Internet connection. </li></ul></ul><ul><li>So I called Jeff. </li></ul>
  18. 21. <ul><li>Of course, my thinking wasn’t completely original. </li></ul>Launchcast was already using a service called iBEAM to put it’s content “close to the edge.”
  19. 22. That Sets the Stage We can reduce traffic on our Internet connection by moving content into our campus network. We’ll see three things that we’ve tried at Bucknell.
  20. 23. 1
  21. 24. iBEAM <ul><li>Hosts content for various “customers” </li></ul><ul><ul><li>(Launch.com, MSNBC, The Archeology Channel, eHow.com, The Golf Channel) </li></ul></ul><ul><li>Streaming server (Real Networks and Windows Media Server) </li></ul><ul><li>On-demand and live content </li></ul><ul><li>Tiered Architecture </li></ul><ul><ul><li>Most popular content “at the edge” </li></ul></ul><ul><ul><li>Other content distributed on iBEAM servers throughout the Internet </li></ul></ul><ul><ul><li>All content available at iBEAM’s central server. </li></ul></ul>
  22. 25. iBEAM <ul><li>iBEAM installed a “MaxCaster” server in the Bucknell network last summer. </li></ul><ul><li>We were the second school in the country to have one installed. </li></ul>
  23. 26. iBEAM’s Architecture Request for content that is on “Bucknell’s” iBEAM server Local iBeam Server Bucknell Network Internet Connection Nearest iBeam Server Request for content that is NOT on “Bucknell’s” iBEAM server iBeam Server iBeam Server iBeam Server
  24. 27. iBEAM Architecture: Live content iBEAM iBEAM Server @bucknell Bucknell Computer Center
  25. 28. What does iBEAM cost? <ul><li>$0 </li></ul><ul><li>(A little rack space) </li></ul>
  26. 29. Who pays for iBEAM? <ul><li>It’s customers! </li></ul><ul><li>(Launch.com, MSNBC, The Archeology Channel, eHow.com, The Golf Channel) </li></ul>
  27. 30. iBEAM Benefits <ul><li>Better performance </li></ul><ul><ul><li>Since some content comes from a local server instead of a server somewhere out on the Internet. </li></ul></ul><ul><li>Reduced traffic on our Internet connection. </li></ul>
  28. 31. Launchcast and iBEAM <ul><li>As we started to work with Launchcast and iBEAM, we realized: </li></ul><ul><ul><li>Launchcast content is available in several bandwidths </li></ul></ul><ul><ul><li>Most of iBEAM’s users are dial-up users </li></ul></ul><ul><ul><li>Therefore, the content on any iBEAM MaxCaster server (including ours) is mostly low-bandwidth </li></ul></ul><ul><ul><li>However, our users are broadband users </li></ul></ul><ul><li>So, very little Launchcast content is served from Bucknell’s iBEAM server. </li></ul><ul><li>So, we haven’t promoted Launchcast to our students as an alternative to Napster </li></ul>
  29. 32. iBEAM <ul><li>However, any content that is delivered from Bucknell’s iBEAM server is still a reduction in traffic on our Internet connection. </li></ul>
  30. 33. The last I heard <ul><li>iBEAM architecture change in the works </li></ul><ul><ul><li>Content on Bucknell’s iBEAM server will be based on Bucknell usage, not global usage (heterogeneous edge). </li></ul></ul><ul><li>Both iBEAM and Launch are struggling financially. </li></ul>

  46. 51. Intertainer Test <ul><li>We are conducting a semester-long test of Intertainer. </li></ul><ul><li>We are their first school to try it. </li></ul><ul><li>Server installed in January, and test started the first week of February </li></ul><ul><li>Limited to one dorm </li></ul><ul><ul><li>320 students </li></ul></ul><ul><ul><li>100 Mbits/sec connections, switched, w/gigabit uplink to backbone, so this should not interfere with anything else. </li></ul></ul><ul><li>If all goes well with the test, we will expand it to the entire campus next fall. </li></ul>

  52. 57. Intertainer Test What do we hope to get out of it? <ul><li>To the extent that our students use Intertainer instead of similar services, they will not be using our Internet connection. </li></ul><ul><li>We are testing our ability to deliver video over our network. </li></ul>
  53. 58. Intertainer Test What do we hope to get out of it? <ul><li>Can this service also be used to deliver course-related movies to students </li></ul><ul><ul><li>in place of three-hour checkout of VHS/DVD? </li></ul></ul><ul><ul><li>Revenue generated from entertainment will be used to cover cost of academic use. </li></ul></ul><ul><ul><li>Some licensing and timing issues to be worked out. </li></ul></ul>

  69. 74. What did we do? <ul><li>Educate - What are others doing? </li></ul><ul><li>Think - What do we want to do? </li></ul><ul><li>Get Input - Users Status of Network </li></ul><ul><li>Educate - Shared Resource for Everyone! </li></ul><ul><li>Get Input - Our Campus Priorities </li></ul><ul><li>Educate - Technical Possibilities </li></ul><ul><li>Get Input - Together Set Policy </li></ul>Nothing
  70. 75. Philosophy <ul><li>Network is a shared resource for a diverse constituency! </li></ul><ul><li>Network has an extremely diverse (and changing) set of applications. </li></ul><ul><li>We are Education - Don’t Ban Anything! </li></ul><ul><li>We are Assumption = Community, Collaboration and Sharing. </li></ul>

  73. 78. Notifying the campus: <ul><li>Email Message(s): </li></ul><ul><li>We have been monitoring the campus network for the past week and are finding that on average approximately 68% of our network usage is from programs like Napster, Scour, and iMesh. These programs are widely known to bring down campus networks because of the amount of bandwidth they use. </li></ul><ul><li>We will continue to monitor the network on campus. We do not intend to ban anything at this time. We are asking the entire Assumption community to limit the amount of bandwidth they are using by limiting the usage of these types of programs. </li></ul><ul><li>We will contact the high bandwidth users of applications such as Napster, Scour and iMesh in an effort to limit heavy network use. </li></ul><ul><li>Asking them to monitor themselves as well. </li></ul><ul><li>Individual users will be asked to decrease their use. </li></ul><ul><ul><ul><ul><ul><li>IT WORKED (decreased Napster traffic) </li></ul></ul></ul></ul></ul>
