Sustainable Network Resource Management System for Virtual Private Clouds

Abstract

To satisfy the requirement of secure isolation of Infrastructure–as-a-Service (IaaS) for enterprise customers, virtual private clouds, which are separated from others by using virtualization technologies, are deployed. However, isolation with virtualization technologies cannot avoid the affect of performance degradation, such as traffic congestion. Therefore, bandwidth-guaranteed virtual private clouds are needed for excluding unintentional and unwanted influence among multiple customers. In this paper, we propose a sustainable network resource management system (NRM) introducing a Changing Mechanism of software module based on the context (CHAMELEON) and a virtual network point for multipoint network provisioning. With the proposed mechanisms, we successfully demonstrated the sustainability of the NRM, which controls six kinds of network equipment without any modification itself.
