Towards realistic benchmarks for virtual infrastructure resource allocators
Qin Yin, Timothy Roscoe · 2012
The rise of virtual infrastructures has renewed research interest in the design and implementation of resource allocators which allow users to reserve or use combinations of (virtual) nodes, switches, and network links on a variety of virtual infrastructures ranging from network testbeds to cloud computing facilities. However, since the area is still relatively new, work on resource allocation lacks realistic benchmarks. In this paper, we suggest how to generate realistic benchmarks for virtual infrastructure, and present our workload generator as an example, which is based on a 5-year trace of experiments submitted to the popular Emulab testbed. We demonstrate the importance as well as potential applications of such benchmarks by using the generated test workload in various evaluation scenarios.
