Stony Brook currently has a 10Gbps connection to the NYSERNet Research and Engineering network through which it also connects to Internet2. NYSERNet operates a multiplexed network across the state interconnecting all of the major research Universities in New York. 

Stony Brook is a Level 1 Internet2 higher education member eligible to take advantage of the high speed Internet2 network.

Anyone at the University who tries to connect to a fellow Internet2 member's website or Internet application from either the wired or wireless network on West Campus, East Campus, Southampton, or Manhattan will automatically be routed through the specialized, high-capacity, high-speed Internet2 network (as long as the fellow Internet2 member has permitted access on the other end).
