Morphology of Modern Data Center Networks: Overview

Form follows function is a modern architectural principle that has been used to design and understand the workings of organisms and buildings. Computer networks are also an example of this principle. The classical networking topology (or form) inside an enterprise (and data center) has been the access-aggregation-core model that was designed to serve the needs of the applications then vogue in the enterprise. Enter the 21st century: companies like Google and Amazon, and applications based on cloud, big data and web 2.0 are redefining the fundamental morphology of data center networks. This talk introduces the fundamental form of modern data center networking and discusses how form follows function in this brave new world. The talk will range from the application needs of the modern data center and how they redefine the network requirements to the most common topology in modern data centers to the protocols used and new technologies.
