Title
Performance analysis of modified BCube topologies for virtualized data center networks.
Abstract
Network virtualization enables the computing networks and data center (DC) providers to manage their networking resources in a flexible manner using software running on physical computers. Thus, using DC topology with high flexibility to the required service-level changes is very important to this purpose. In this paper, we address the existing issues with the classic DC network topology in virtualized DC networks and investigate the performance of a set of modified BCube topologies with the capability of providing dynamic structures according to the bandwidth requirement in a virtual DC network. In particular, we propose three main approaches to modify the structure of a classic BCube topology as a topology benchmark and investigate their associated structural features and maximum achievable interconnected bandwidth for different routing scenarios. Finally, we run an extensive simulation program to check the performance of the proposed modified topologies in a simulation environment which considers the failure analysis and also traffic congestion. Our simulation experiments, which are consistent to our design goals, show the efficiency of the proposed modified topologies comparing to the classic BCube in terms of bandwidth availability and failure resiliency.
