  1. NSIS Interoperability Meeting12-13 October 2006 University of Coimbra Portugal

  2. Summary • Participants • Implementations • Tests • Methodology • Issues • Conclusions

  3. Participants • University of Coimbra (UoC) • Luís Cordeiro • Luís Conceição (GIST) • David Palma (QoS NSLP & QSPEC) • Rui Vilão (NATFW NSLP) • Vitor Bernardo • University of Göttingen (UoG) • Bernd Schloer (QoS NSLP) • Henning Peters (NATFW NSLP) • University of Karlsruhe (UKA) • Roland Bless • Matthias Friedrich

  4. Participants • Roke • Alan Ford • Ericsson • Ferenc Pintér • Attila Bader • University of Twente • Rudd Klaver (remotely only) Total of 13 persons from 6 organizations

  5. GIST UoC v11 UoG v11 UKA v11 Roke v09 UoT v09 (remotely only) QoS NSLP UoC v11 UoG v11 UKA v09 Ericsson v06 [using UoG GIST] NATFW UoC v12 UoG v11 UKA v12 Implementations

  6. GIST Stateless mode D-Mode Handshake C-Mode Handshake (TCP) C-Mode Handshake (SCTP) C-Mode Handshake (TCP) with TLS/SSL Timers Error messages Packages torture: Header MRI State refresh IPv6 Multiple flows in parallel in D-Mode Multiple flows in parallel in C-Mode (with association reuse) Multiple nodes (message interception) QoS NSLP Create sessions Update sessions Remove sessions Receiver initiated reservation Query probe Error cases Multiple sessions in parallel Multiple nodes Packages torture NATFW NSLP Create Update Remove Trace Error cases Proxy mode Lifetime maintenance Asynchronous termination Packages torture Tests done/scheduled • Different subsets of these tests were done depending on the implementations interacting • The interacting team chose the tests to perform depending on their concerns A detailed list of tests and methodology MUST be made to the next interop

  7. Important Issues • GIST • Use of Stack-Configuration-Data and MA-Protocol-Options • MA-Hold-Time issues • GIST Hop count • QoS NSLP: • Receiver initiated methods • Is notify required to acknowledge every refresh message? • All issues have been taken to the mailing list • Many spec clarification issues were taken directly to the author

  8. Conclusions • GIST • Several implementation issues were discovered and most of them solved on site • Not all features were tested • Only back-to-back tests were made • Few package torture were made • There are interoperable implementations • The spec is clear and "simple" enough to produce running and interoperable code. • NSLPs • Several implementation issues were discovered and most of them solved on site • There are interoperable implementations • There are still some issues with the spec

  9. Conclusions • Interop meetings are very good to: • Fast testing • Fast debugging • Discuss implementation issues • Discuss specification unclear parts • New interop is needed • Should have more days (3-4) • Have a very detail methodology and test sequence defined • All intervenient should have the same spec version implemented • Roland Bless offered University of Karlsruhe (Germany) to held the next interop • When?
