The Mordia Project
The Mordia prototype
Optical circuit switching (OCS) potentially allows for less costly and more energy efficient datacenter networks compared with traditional electronic packet switched networks when operating at link rates of 40G and higher. One criticism of earlier projects such as Helios [SIGCOMM '10] and c-Through [SIGCOMM '10] was that they employed OCS technology with reconfiguration times on the order of 15 milliseconds or longer [OFC '11], limiting the utility of the resulting hybrid datacenter network to long-lived communication patterns with hotspots (elephants). MORDIA (Microsecond Optical Reconfigurable Datacenter Interconnect Architecture) is an effort to explore the use of OCS technology in datacenter networks with microsecond reconfiguration times. Because no such fast OCS was available, we constructed our own 24-port OCS with a reconfiguration time of 2.8 microseconds, as seen in the photo. This website hosts the Mordia user interface and you can navigate the menu items to see Mordia's operation in real time.
