  1. The design of connectivity detect system by reuse of SPAM Mail Koji OKAMURA and Hiroaki Towata Kyushu University

  2. Our Idea ASxxyy ASzzzz ASxxxx ASxxzz ASyyyy ASyyzz Investigation for connectivity are interesting. Active method (ICMP Echo etc) is not scaled.

  3. Our Idea ASxxyy ASzzzz ASxxxx ASxxzz ASyyyy ASyyzz Useless SPAM Mail may be used for this!

  4. The Merit of using SPAM Mail • TCP • Re-transmission • We can use what are necessary from so huge SPAM Mail.

  6. Re-transmission • If no SPAM Mail, • Trouble of Connectivity • Actually no SPAM • Re-Transmission of e-mail help to analyze this. • E-mail has time stamp • We can use what are necessary from so huge SPAM Mail.

  7. Example Analysis • The analysis by referring the time lag. • I plot the mail communication when the time lag is more than 1 hour. AS number Day

  8. Future Works • How to distinguish the trouble when we don’t have SPAM. • How to Display AS which may have trouble. • We should not know AS path topology. • Study Behavior of re-transmission of SPAM • How many ASes will be covered by our method?
