  1. Case Study: GT-SJTU Warren Matthews (GT)

  2. Georgia Tech (GT) has adopted an international focus in its strategic plan. GT has a presence at a number of Universities around the world. One is Shanghai Jiao Tong University (SJTU). Overview Office of Information Technology http://www.oit.gatech.edu

  3. The goal is for faculty and students to have access to all the resources that they would have if they were in Atlanta. However, there are reports from faculty and students that most applications are slow. The number of faculty and students will grow dramatically this summer. Overview Office of Information Technology http://www.oit.gatech.edu

  4. Data gathered in January and February 2006. Measured from SJTU. Cron runs traceroute every 10 minutes. Cron sends 10 pings every 10 minutes. Measurements Office of Information Technology http://www.oit.gatech.edu

  5. Particularly heavy tailed. peak 291ms median 299 ms mean 350 ms maximum 6095 ms. Results - RTT Office of Information Technology http://www.oit.gatech.edu

  6. Same dataset Jitter is ti-ti-1 Median is 0 ms Mean is -0.67 ms IQR is 37 ms Results - Jitter Office of Information Technology http://www.oit.gatech.edu

  7. traceroute from SJTU ~6000 times. Currently blocked Tremendous amount of repeated or non-responsive hops. 1849 “different” routes. Results - Routing (1/2) Different only in terms of comparing the output of traceroute hops. Office of Information Technology http://www.oit.gatech.edu

  8. Routing (2/2) SJTU (5) SHERNET (3) PacificWave (1) CERNET (9) KR (5) Abilene (2) APAN (1) APAN (3) SOX (2) Transpac (1) GT (3) The number in parenthesis is the number of hops within the AS. Office of Information Technology http://www.oit.gatech.edu
