"Jellyfish: Networking Data Centers, Randomly"

(Vortrag im Rahmen der "MPI Distinguished Lecture Series" in Kooperation mit dem Fachbereich Informatik)

Large Internet services, “big science”, and increasingly, industrial R&D, are all powered by warehouse scale computing - tens of thousands of servers connected over a network. Increasing parallelism and big data analytics require that the network provide high throughput connectivity. In this talk, I will describe Jellyfish, our proposed design for such a network. Jellyfish uses a random graph topology, allowing construction at arbitrary sizes, easier network growth over time, and integration of newer and more powerful network equipment as it becomes available - practical problems that rigidly structured traditional networks fail to address. Surprisingly, Jellyfish also beats state-of-the-art real-world designs on throughput, by as much as 40%. In fact, we show that Jellyfish networks achieve near optimal throughput, i.e., one cannot build, using the same networking equipment, *any* network that provides much higher throughput.
