  1. A stateless Ping tool for simple tests of GIMPS implementations<draft-juchem-nsis-ping-tool-02> Christian Dickmann, Ingo Juchem, Sebastian Willert, Xiaoming Fu University of Göttingen

  2. Outline • Motivation • Design • Extensibility • Implementation status • Next steps

  3. Motivation • Initially: • to run GIMPS signaling along a chain of GIMPS nodes without the need for a full-fledged NSLP • It is designed also to: • Gather information about the signaling nodes along the path: • Currently, IP addresses and timestamps (to calculate RTTs) • Others are possible: e.g., NTLP and NSLP states

  4. Design • Design as light-weight probing NSLP • Initiator sends Ping Message with list of requested information (objects) • Each Ping-aware node on the path adds the requested objects • Receiver forwards Ping Message upstream towards the Initiator • Intermediate nodes add information (e.g. timestamps) twice • Round Trip Times can be calculated

  5. Extensibility • Current objects: • IP address (IPv4 or IPv6) • Timestamp • Ping Tool can be extended with new object types • If objects are unsupported, an indication is added • Possible new objects: • List of supported NSLPs • NTLP layer state information • State information of supported NSLPs • Security considerations need to be addressed

  6. Implementation status • Ping Tool-01 implementation is now part of our NSIS implementation release (GIMPS draft 06) • http://user.informatik.uni-goettingen.de/~nsis/ • Together with a release of Ethereal dissectors for: • GIMPS draft 06 • Ping Tool 01 • We have also successfully passed the ping implementation interoperability test in the interop event

  7. Next steps • Is this work useful? • Shall this be adopted by the WG as a "Diagnostics NSLP"?

  8. Thanks
