Researchers in the Computers, Media, and Communciation Laboratory investigate how to build the networked (distributed) systems of the future. Our main emphasis is on the interaction of networks and applications. New networks, e.g., next-generation Internet designs, high-speed datacenter networks, and wireless and sensor networks, provide both rich functionality and unique challenges for developers and applications. Our researchers tackle the problems arising in these contexts in a variety of ways:

• How can the network manage its resources so that it best supports the application? ("Application-aware networks", an example of an active network)
• How can we construct applications so that they can adjust their resource demands in response to changes in the network? ("Network-aware" or "system-aware" applications).

CMCL Infrastructure

CMCL maintains a number of research network testbeds. Our machine room, connected to the main laboratory space, houses CMULab, the CMU Emulab cluster, and a number of project-specific clusters. We are currently building the HomeNet residential wireless testbed. We also maintain an internal wireless testbed scattered throughout Wean Hall, and administer the RON wide-area testbed.
