Robust and Scalable Structure for Server-Interconnections in Data Centers

Abstract: Data center networking is the result of many server machines interconnected. The present data centers are connected using network switches organized in the form of a tree hierarchy. However, they are unable to meet the goals such as establishing data center network with low cost equipment, fault tolerance and balancing the capacity of network. Recently Dan Li et al. presented a new server-interconnection structure. This structure makes use of the both Ethernet ports that come with commodity server for server-interconnections. Thus it makes the data center structure highly scalable and efficient. In this paper we implement this structure by implementing a custom Java simulator. We also implement traffic aware routing mechanisms to improve robustness of the data center. The experimental results revealed that the proposed design is effective and robust to failures.

Keywords: Data center, server interconnection structure, scalable routing, and fault tolerance
