Scenario-based Model-driven Configuration Management Proof-of-Concept

In this page you will find a software package that can be used to check the feasibility of scenario-based model-driven configuration management for experimentation infrastructures (i.e., testbeds) based on TIM-to-TSM transformations.

Release	Date	Comments
TIMTransforms-v2009_09_02.tar.gz	02/Sep/2008	Upgrade base CIM Schema version (2.18.1 -> 2.22.0) Changes in TIM: TIM_TransmissionCharacteristics now derives from CIM_LogicalElemeent (former derivation from CIM_SettingData avoids defining new local and propagated keys) Defined InstanceID as local key property in TIM_TransmissionCharacteristics Defined LinkInstanceID as propagated key property in TIM_TransmissionCharacteristics Removed GatewayIPv6Address from TIM_StaticIPv6AssignmentSettingData (it was not used)
TIMTransforms-v2008_10_15-p1.tar.gz	01/Dic/2008	very minor change: added a newline at the end of reset_cimon.sh script (we suspect of problems in some cases due to this in the previous version). Thanks to Walter Fuertes for the debugging and reports :)
TIMTransforms-v2008_10_15.tar.gz	15/Oct/2008	Initial release

Note that here we provide a software proof-of-concept, but not the details of the scenario-based model-driven configuration management approach. Such details (e.g., architecture, TIM-to-TSM transformations principles, the Testbed Independent Model semantics, information regarding VNUML-based and ADRENALINE testbeds, etc.) are provided elsewhere (although if you are reading this you maybe have come from some of those sources and you are already aware of the details :)

Within the .tar.gz package you will find:

The TIM (Testbed Independent Model) specification, in DMTF's MOF.
The validation set, composed of three different scenarios (basic, NSFNet and RedIris) specified in DMTF's MOF conforming to TIM.
The Java source code implementing the TIM-to-TSM transformations for VNUML-based testbed and the ADRENALINE testbed, along with Javadoc documentation for it.
Some supporting material (e.g., helper scripts).

Further details (prerequisites, installation, etc.) are provided in the README.txt that comes with the package. All the materials within the package can be used under the terms of GPL and Creative Commons Attribution-Share Alike 2.5 Spain licenses for software code and models/documentation, respectively.

Don't hesitate to contact me if you have problems using the software or any other question. In addition, feedback (regarding the software implementation or the ideas behind it) is highly appreciated!

Troubleshooting

Sometimes the MOF compilation fails with a "VER_ERROR:Unsupported version 1" error. This problems has been found in Fedora 11 (no problems has been detected in Debian or Ubuntu). The cause is yet unknown but it seems some kind of problem with the RMI interaction between mofcomp and the CIMOM server on port 5987 (wireshark may help to debug). (22/Jul/2009).
