Hybrid architecture for a scalable Data Center Network Based on Blockchain and SDN

Abstract

Nowadays, the Internet services become a main part of our daily life. Almost all of the internet services are run in data centers, where a massive number of servers are connected through intra-data center networks (DCNs). However, the majority of internet traffic is inside data centers. The traffic in hyperscale data centers doubles every one to two years, which presents a scalability challenge for intra-data center interconnects and networking. The rapid rise of web based applications and cloud computing over the last decade has led to a growing interest in data center technologies. Scalability, in DCNs, is one of the foremost challenges. With the advent of cloud paradigm, data centers are required to scale up to hundreds of thousands of nodes. Therefore, Scalability, in DCNs, is one of the foremost challenges. One solution is to change the data center topology to mitigate the problem. In this paper, we have proposed an architecture that combines SDN and hyperledger fabric. We have built a prototype for the proposed solution. We also define some performance metrics for evaluation. The metrics include network latency, throughput, and execution times. In this paper, we have just proved that the proposed solution is applicable. Discussion of the results, performance and comparison with the results of other solutions will be handled in a subsequent paper.
