Philippe COUSIN

ETSI Services Sales Director

IPv6 SummitBeijing, 15 -16 April 2008


European ipv6 test capability

Europe has a long experience in providing test specifications in support of the single EU market or its consolidation today.

For that ESOs (European Standardisation Bodies) have gained experience and developed specific methodologies addressing testing, certification and interoperability

EU has agreed to support the use of such experiences and methodologies in the IPv6 field and subsequently :

  • Support +1, 5 millions € to the development of IPv6 test suites by ETSI

  • Support + 1million € to the development of free, open test platform executing the IPv6 test suites

4th e-Infrastructure Concertation Meeting

ETSI approaches in Testing and interoperability

  • The ability of systems and products to interwork is fundamental…

  • ETSI’s set of unique and complementary resources to help ensure interoperable standards:

    • Technical Committee MTS (Methods for Testing and Specification)

      • Development of methodologies, techniques and languages http://portal.etsi.org

    • ETSI’s Centre For Testing and Interoperability (CTI)

      • Supports ETSI committees on the application of formal techniques in standards on a daily basis

      • Development of test specifications (conformance and interop)

        http://www.etsi.org/ptcc

      • Plugtests™ Service

        • Validation of standards and prototypes through interoperability events

          http://www.etsi.org/plugtests

Ipv6 test specifications ec funded project stf 276

IPv6 Test Specifications EC funded project STF 276

Joint ETSI – eEurope project

Writing IPv6 IOP & Conformance test suites

Supported by the ETSI membership

Require IPv6 test specifications using ETSI methods and test languages

Designed to be part of 3GPP and TISPAN NGN IPv6 testing strategies

Active contributors: mainly vendors

Liaising with other IPv6 projects

IPv6 Forum (ready logo group)

GO4IT

Our output (TTCN-3 Test Cases) = one of their inputs

GO4IT charter = provide an open test tool


Ipv6 testing framework requirements process

IPv6 Testing FrameworkRequirements Process

  • Implemented as a scalable database containing all requirement elements

  • Web interface offering:

    • Browsing by function

    • User-defined search

    • Links to RFC and related test specification

Ipv6 testing framework conformance test cases

IPv6 Testing FrameworkConformance Test Cases

  • Detailed TTCN-3 test script that implements test purpose

    • can be compiled and executed

  • Composition

    • a preamble

    • test body (i.e., implementation of the Test Purpose)

    • A postamble

  • Assigns test verdicts

  • Handles unexpected behaviour as well as the behaviour in the test purpose

  • Can be distributed over parallel test components

  • Can be entirely automated

  • Configurable at run-time, e.g., SUT address

Ipv6 testing framework example ttcn 3 test case

IPv6 Testing FrameworkExample TTCN-3 Test Case

testcase TC_COR_0047_01() runs on Ipv6Node system EtherNetAdapter {

f_cf02Up(); // Configure test system for HS->RT

// No preamble required in this case

f_TP_HopsSetToOne(); // Perform test

// No postamble required in this case

f_cf02Down(); // Return test system to initial state

}

function f_TP_HopsSetToOne() runs on Ipv6Node {

var Ipv6Packet v_ipPkt;

var FncRetCode v_ret := f_echoTimeExceeded( 1, v_ipPkt );

if ( v_ret == e_success and v_ipPkt.icmpCode == 0 )

{ setverdict(pass);}

else { setverdict(fail); }

}

function f_echoTimeExceeded(in UInt8 p_hops, out Ipv6Packet p_ípPkt ) runs on Ipv6Node return FncRetCode {

var Ipv6Packet v_ipPacket; var FncRetCode v_ret;

ipPort.send( m_echoReqWithHops(p_hops) );alt {

[] ipPort.receive( mw_anyTimeExceeded ) -> value p_ipPkt

{ return e_success } [] ipPort.receive { return e_error } }

Ipv6 testing framework the ttcn 3 library

IPv6 Testing FrameworkThe TTCN-3 Library

  • Each test uses this library

    • Decreases test code size and improves its quality

    • Reduces time to develop new tests

  • Contains useful definitions for different purposes

    • Test component synchronization

    • Basic IPv6 packet exchanges

    • Preamble, test purpose, and postamble code

    • Test configurations

    • Code for driving upper IPv6 interface

  • Extensively documented

  • Easily add tests to test suites

  • Will be freely available on the web
