Slide 2

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


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

ETSI approaches in Testing and interoperability

2005: IPv6 Core test development

2006: IPv6 Security (IPsec) test development MIPv6 test development IPv4 to IPv6 Transitioning test development

ETSI IPv6 Activities


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 FrameworkExample Test Description

Identifier:

Step Step

Test Purpose: TP_COR_1100_01 Reference: RQ_001_2935 Configuration:

TD_COR_1100_01Summary EUT reassembles a fragmented packet of an original length less than 1500 octets

with { the MTU on Link1 set to 1400 octets } ensure that { when { QE is requested to send data requiring a packet_length greater than 1500 octets } then { EUT indicates receipt of the same data without modification } }

Pre-Test Conditions:

MTU set to 1400 octets on link1

Verdict

1

2

3

Cause QE to send an Echo Request to EUT with a packet size of 1450 octets and with each octet set to the hexadecimal value "F0"

CF_COR_11

Check: Does protocol monitor show that the Echo Request was sent from QE to EUT?

Yes No

Check: Does QE receive an Echo Reply from EUT with the packet length the same as the Echo Request and with each octet containing the hexadecimal value "F0"?

Yes No

Pass Fail

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

Project identity card

Integrated Infrastructure Initiative

Started in Nov 2005 30 month FP6 project

Partners:

France (jTest, INRIA) Europe (ETSI) Germany (inno, Fokus) Spain (Cetecom) China (BII, CATR, BUPT) Russia (Ispras) Brazil (IPT)

Go4IT project intends to provide Research Infrastructure users with free TTCN-3 based IPv6 testing environment including test tools, test suites and the related services.


Overview of activitiesFree consultancy support

for IPv6 testing

Free executable IPv6 test suites

Open-source TTCN-3 test

platform

Users’ workshopsConferences

Interoperability events


27

Go4IT package 1

Package 1 will permit quick offer and quick supply of test services to IPv6 community

It will propose

An Executable Test Suite based on the ETSI IPv6 STF276 work

An Executable Test Suite based on an IPv6 « hot-topics » ATS to be defined during the users’ needs analysis

As a minimum, all the runtimes required to run the ETS will be provided


28

Go4IT package 2 Package 2 roadmap targets a term longer than the project itself Package 2 focus is ‘open’ and ‘generic’ TTCN-3 test environment

Open means• Conform to TTCN-3 specification• Based on open-source principles

Generic means• Environment can incorporate user adaptations• Use of vendor-specific code into ATS will be avoided• Target re-usability of developed modules with other TTCN-3 test environments

Package 2 will propose within Go4IT

The technical roadmap An Open Source software forge A working demonstrator of the Go4IT test environment


TTCN-3: an open test system architecture


GO4IT: strong collaboration with China
