Data Center Networks: Trends, Opportunities, and Challenges

Speaker:  Samee U Khan – Fargo, ND, United States
Topic(s):  Applied Computing


The major Information and Communication Technology (ICT) components within a data center are: (a) servers, (b) storage, and (c) interconnection networks. The data center network (DCN) is considered the communication backbone of a data center; consequently, a DCN is one of the prime design concerns in the data center, which plays a pivotal role in ascertaining the performance factors and initial capital investment. However, the legacy DCN infrastructures inherently lack the capability to meet the current growth trend and bandwidth demands. The legacy DCN architectures mainly suffer from: (a) energy-inefficiency, (b) poor scalability, (c) high cost, (d) low cross-section bandwidth, and (e) non-agility.


In this talk, we will discuss a few legacy DCN architectures and elaborate on the current industrial standard DCN architectures, such as the fat-tree, DCell, VL2, BCube, flattened butterfly, and FiConn. We will discuss the current trends in DCN architectural research and elaborate on the challenges, such as (a) performance, (b) reliability, (c) fault tolerance, (d) high end-to-end bandwidth, and (e) agility that will quantify for several research opportunities.
