Facebook Fabric Networking Deconstructed

Facebook engineering has recently introduced their next-generation data center network architecture planned to be operational in the new Altoona facility. Introducing data center fabric, the next-generation Facebook data center network

In this post we are going to look at the design proposed and break down some of the reasons why this design was necessary although maybe still not ideal.

Facebook, the killer app.. literally

Within Facebook’s data center the network is a critical component driving this social networks ever increasing appetite to connect people together. The challenges unfold on two axis, the first being the explosive growth in the user population and its increasing demand and access bolstered by modern mobile devices and the second related to the exponential growth of machine to machine traffic required to aggregate and compose information which we all know and love. Due to the nature of Facebook applications, machine to machine communications is “several orders of magnitude larger than what goes out the Internet”

The need to parallelize work becomes a daunting task in this environment requiring an enormous communication fabric for internal processing.

the rate of our machine-to-machine traffic growth remains exponential, and the volume has been doubling at an interval of less Continue reading
