Performance and Limitations

Providing mobility between the domains is an essential GSN principle; however, there are technological constraints with regards to acceptable performance, and there are limitations due to limited interoperability between different management solutions and domain policies. It will be important to identify and model performance & limitations in connection with migration over the GSN infrastructure. This is a required step for improving the decision making algorithms of the management tools.

1. Architecture

The performance and limitations will be evaluated through a mix of simulation and experimentation over the GSN. Simulations will provide the ability to have scalable analysis.

2. Tools

The tool used in this work will mainly be Matlab simulation, using predictive models. New modes will be implemented and tested with the Haizea lease manager and the OpenNebula cloud manager.
