Abstract
Embodiments of the invention describe flexible (i.e., elastic) data center architectures capable of meeting exascale, while maintaining low latency and using reasonable sizes of electronic packet switches, through the use of optical circuit switches such as optical time, wavelength, waveband and space circuit switching technologies. This flexible architecture enables the reconfigurability of the interconnectivity of servers and storage devices within a data center to respond to the number, size, type and duration of the various applications being requested at any given point in time.

A method for routing data in a switch network, the method comprising:
- receiving, by a plurality of edge switches, data packets from a plurality of host devices, the plurality of edge switches arranged in a first switch level, the switch network further comprising a second switch level and an optical switch level arranged between the first switch level and the second switch level, the second switch level comprising a plurality of electronic switches, the optical switch level comprising one or more optical switches that are configured to change connections between the first switch level and the second switch level;
- changing connections between the first switch level and the second switch level of electronic switches using the one or more optical switches in the optical switch level;
- and
- receiving, by a plurality of spine switches in the second switch level of electronic switches, the data packets using the connections changed by the one or more optical switches in the optical switch level.
A switch network comprising:
- a plurality of edge switches configured to receive data packets from a plurality of host devices, the plurality of edge switches arranged in a first switch level, the switch network further comprising a second switch level and an optical switch level arranged between the first switch level and the second switch level, the second switch level comprising a plurality of electronic switches, the optical switch level comprising one or more optical switches that are configured to change connections between the first switch level and the second switch level;
- a plurality of spine switches in the second switch level of the electronic switches, the plurality of spine switches configured to receive the data packets using the connections changed by the one or more optical switches in the optical switch level.
