Simulation framework for FEDERICA Sample Clauses

Simulation framework for FEDERICA. In this chapter, the basic motivations and the implementation details of the simulation framework tailored to FEDERICA are discussed. This is additional work (not part of the original project Description of Work) which the JRA2 partners have agreed upon based on the progress of the project. The initial need for this simulator was mainly rooted in the fact that the actual usage of the FEDERICA infrastructure was not sufficient at that time (in 2009) to provide enough inputs to perform the detailed fairness, resource allocation, and business-related studies by the Joint Research Activities. That is why it was decided to develop the simulation framework but in the meantime other useful aspects have emerged. Finally, it can be said that the simulator supports: • Planning and development of the FEDERICA physical infrastructure (potentially useful for planning any follow-on project of XXXXXXXX). • Planning of the slice creation process and its effect on the network performance (useful for NOC and daily operation). • Better understanding of the users’ behaviour in a virtualised environment (useful for business-related research and potential commercialization later on). This chapter contains a brief description of the FEDERICA simulation framework as well as an additional theoretical study on the fairness limitations in FEDERICA. Note that the simulator source code and executable files are available to all the FEDERICA project partners on the FEDERICA project Wiki page.

Simulation framework for FEDERICA. A well-known practice in the commercial world is using specific simulations tailored to the given infrastructure (and broader environment) to study real life situations in production networks. In this section, the FEDERICA simulation environment is described. GSSIM (Grid Scheduling Simulator) [Gss] is software for performing simulations which provides a comprehensive environment enabling researchers to test resource management algorithms and architectures. For the purposes of the FEDERICA project, GSSIM was adapted to test different approaches towards resource allocation based on a given demand model. Emphasis was put on simulating an exact infrastructure, as close to the problem as possible. Note that the following description is restricted to the simulation framework only which tries to cope with the real FEDERICA architectural component (defined by JRA1 in deliverable DJRA1.1) and in parallel tries to be flexible enough to implement other (future) components as well.
