Abstract: A computer system (such as a controller) that selects channels and/or channel widths for use during communication in a shared band of frequencies is described. During operation, the computer system may receive, associated with access points in a region (such as a zone), information specifying unavailable channels associated with the shared band of frequencies, where the unavailable channels are currently used by the access points. For example, the information may be included in access-point status reports from the access points. Then, based at least in part on the unavailable channels, the computer system may determine the channels and/or the channel widths for use by the access points during communication in the shared band of frequencies in the region. Next, the computer system may provide, addressed to the access points, second information specifying the determined channels and/or the channel width.

Abstract: An intelligence-defined optical tunnel network system includes multiple Optical Switch Interconnect Sub-systems (OSIS), in which a first OSIS is configured to transmit a first lateral transmission optical signal via a first line to a second OSIS, and transmit a second lateral transmission optical signal via a second line to the second OSIS. The second OSIS includes a failover sub-module and a micro-control unit. The failover sub-module is configured to output one of the first and the second lateral transmission optical signal based on a selective signal. The micro-control unit is configured to output the selective signal to the failover sub-module to control the failover sub-module output the second lateral transmission optical signal if a signal intensity of the first lateral transmission optical signal is lower than a threshold value.
