IETF65 DIME WG V. Fajardo, A. McNamee, J. Bournelle and H. Tschofenig Diameter Inter Operability Test Suites (draft-fajardo-dime-interop-test-suite-00.txt)

IETF65 DIME WG General Notes: Document is a set of test cases and provides guidelines, it does not provide test plans Document does not re-state what is already mandated in a particular specification –Test cases provides references to specifications Provides recommended topologies for test cases –Topologies are design to test multiple cases with multiple participants (In the interest of time) –Topologies are not mandated

IETF65 DIME WG General Notes Con’td: Test cases attempts to exercise the most common/necessary functionality Test cases are generalized. –Correctness and conformance is emphasized only in the context of peer interaction Detailed behavior encroaching in the implementation specifics is left to the testers End-to-end and/or Hop-by-hop security is left to the testers to exercise

IETF65 DIME WG Brief Overview – Application Coverage: Base Protocol Credit Control SIP 3GPP - currently only Cx, Sh and Rf. Maybe Ro will be added if there is interest EAP NASREQ MIP

IETF65 DIME WG Brief Overview – Base Protocol Base protocol concentrates on connectivity and peering  Capabilities exchange, request/answer routing, failover/failback, loop detection etc.  More topology setup required for connectivity and routing test Some agent tests can overlap with other application tests Proxies may require additional topology setup but can also overlap with some applications Session maintenance can be done along with application testing

IETF65 DIME WG Brief Overview – Application Coverage CC and SIP/3GPP will probably be the most implemented  Some test cases emphasizes message exchanges  Test cases are more extensive Test topologies maybe less important – verification maybe more localized to end peers (i.e. verification of balance checks, direct-debit, refunds etc) Simulation of service elements (nas, sip servers, app servers etc) are left to the testers

IETF65 DIME WG Brief Overview – Application Coverage EAP and NASREQ has simpler topologies. Limited number of participants per topology EAP methods left up to test pairs to agree upon Simulation of access elements (ppp clients etc) are left to the testers

IETF65 DIME WG Brief Overview – Application Coverage MIPv4 test cases emphasize different deployment scenarios - require more effort in topology setup to simulate different registration schemes Much of the details in terms of accounting is left to the test participants to verify Same with authentication and authorization schemes

IETF65 DIME WG Reviews Only one extensive review so far Review limited mostly to Base protocol and CC
