OpenSS7 License

Description: OpenSS7 License OpenSS7 License.

Software licensed under OpenSS7 License is licensed under a proprietary license only. This includes primarily: (Please refer to the Copyright notices and licensing terms included with the specific software.)

  • Conformance Test Programs
  • Performance Test Programs
  • Interworking Test Programs

Software provided by OpenSS7 Corporation for these purposes normally has the license terms that can be found here. There are a number of reasons why the OpenSS7 conformance, performance and interworking software does not have an open license:

  1. Conformance Test Programs should be modified only if there is an error in the validity of the conformance test. Conformance tests are provided by OpenSS7 Corporation for the sole purpose of testing the conformance and validity testing of the OpenSS7 stacks. Use of this software for testing products other than the OpenSS7 stacks is strictly prohibited. (However, license for that purpose can be obtained from OpenSS7 Corporation.)

  2. If conformance test programs were permitted to be modified, it would not be possible to have a strict baseline on the test results necessary to ensure conformance to applicable conformance standards and specifications.

  3. Performance Test Programs can be modified to skew or invalidate the performance test. Performance test programs which are not modified provide a benchmark for further testing of the OpenSS7 stacks and protocol modules. As such, these programs should not be modified. Therefore, modification of test programs remains under the strict control of OpenSS7 Corporation.

  4. If performance test programs were permitted ot be modified, it would not be possible to have a strict baseline on the test results necessary to ensure conformance to performance objectives of applicable standards and specifications.

  5. The same is true for specific interworking tests (such as those provided for TALI). It would be difficult to maintain a strict baseline on test results if these programs were permitted to be modified.

However, conformance, performance and interworking programs may be distributed with the OpenSS7 stacks without change; however, no license is given to modify the programs. Checksums are included with OpenSS7 source releases at the Beta level and beyond to allow the recipient of a distribution to check that the conformance, performance and interworking test programs have not been modified. The OpenSS7 Project will provide MD5 checksums on its downloads page with each distribution to allow a recipient of an OpenSS7 stack to ensure that the software being used comes from an authoritative release and that baseline test results are applicable.

OpenSS7 provides some software which has restricted distribution and modifications. This is primarily conformance, performance and interworking test software. The reason for restricting modifications to the software is that test results for conformance, performance and interworking are heavily tied to the coding of the test software. As a result, this software is provided only for the purposes of testing the OpenSS7 stacks with which it is distributed and cannot be modified.

OpenSS7 Corporation provides licensing of test programs for use in testing software other than OpenSS7 products.
