Berkeley NetSys Lab

We design and build networked systems — from Internet architecture and congestion control to edge computing, datacenter infrastructure, and cellular networks.

Publications People

The NetSys Lab at UC Berkeley pursues foundational research on networked and distributed systems. We are part of the EECS department and work across Internet architecture, systems performance, edge computing, wireless networks, and memory systems. The NetSys Lab is directed by faculty members Rishabh Iyer, Sylvia Ratnasamy, and Scott Shenker.
