A Distributed Virtual Data Center Network Architecture for the Future Internet

摘要

Network virtualization was proposed to meet the challenges of the future Internet. Existing virtual data center network architectures are lacked to exploit the features of network virtualization. Therefore, in this paper, we propose a distributed virtual architecture that groups virtual machines into clusters of different service types. This architecture introduces a concept of abstraction layer consisting of virtual switches that are grouped together to acts as a cluster head. In comparison with existing architectures, our approach tends to enable several features of network virtualization such as scalability, flexibility, higher bandwidth, etc. However, in this work, we evaluated the failure of servers and virtual machines to prove the efficiency and scalability of this architecture.
