Dear all, In the p2psip diagnostics draft version 03, as for "Traceroute" mode, we classify the diagnostics into two application scenarios. (1) In trusted p2p overlays, we use an Echo request message, it is received and disposed by each peer along the routing path, and each peer along the path returns an Echo response message with local diagnostics information including the result and causes if existing. I present that in last IETF meeting. (2) In open p2p overlays, we extend the Route_Query method for retrieving diagnostics information iteratively. If Echo method is used in open p2p overlays, it may cause potential DoS attacks in the overlay.
As for the diagnostic information, we now use a flag to indicate which information the initiator is interested in (which bit for which kind of diagnostic information is TBD), the responder will send back the diagnostic information accordingly (must also consider authorization issue), however, it may cause the extensible problem. How about using structure for the diagnostic information?
