Hyperscale Data Center Networks with Interconnected Transparent Island Architecture
A large number of daily Internet users generates enormous quantities of new data, driving the sensational escalation of Internet giants, such as Google, Facebook, Amazon, IBM, Dropbox, Alibaba, Microsoft, and so on. New data from Synergy Research Group shows that the total number of hyperscale data centres increased to 504 at the end of 2019 [1]. This number was 338 in 2016 and will reach to 628 by the end of 2021 [2]. In order to cope with this massive demand, the size of the data centres is expanding, number of data centres is growing and a technological change in the data centres has been accelerated remarkably over the past decade. Since we are approaching towards the era where many services must meet strict latency requirements. Therefore, the distance (number of hops) between users and servers as well as between server and server must be reduced. In this paper, we propose a new hyperscale DCN called interconnected transparent island (ITI) to achieve reduced number of hops. The proposed ITI architecture is scalable horizontally while the number of hops remains constant as the data centre grows.
