Impact Of Network Protocols On Data Center Applications, Pawan Prakash

Open Access Dissertations

Data centers containing hundreds of thousands of servers have become the foundation of modern computing infrastructures. Enterprises are increasingly deploying new applications and moving existing applications to these large-scale data centers. These networked applications communicate via a set of conventional network protocols, which were originally designed for wide area networks. In this dissertation, we study the impact of different networking layer protocols on the performance of data center applications.

At the transport layer, we observe that bandwidth sharing via TCP in commodity data center networks, which are organized in multi-rooted tree topologies, can lead to severe unfairness under many common …
