Abstract: Today's communications require an effective yet scalable way interconnection of data centers and warehouse scale computers (WSCs) whilst operators must provide a significant portion of data center and WSC applications free of charge to users and consumers. At present, data center operators face the requirement to meet exponentially increasing demand for bandwidth without dramatically increasing the cost and power of the infrastructure employed to satisfy this demand. Simultaneously, consumer expectations of download/upload speeds and latency in accessing content provide additional pressure. Accordingly, the inventors provide a number of optical switching fabrics which reduce the latency and microprocessor loading arising from the prior art Internet Protocol multicasting techniques.

Specifically, a channel frequency profile which includes a center frequency and channel-width (i.e., channel bandwidth) is dynamically assigned to each of one or more APs in a wireless network.

In this regard, each AP's channel frequency profile can be continuously or periodically changed such that the entire available frequency spectrum is effectively utilized and/or interference between APs is avoided or limited. This, in turn, enhances the throughput capacity and/or bandwidth distribution fairness of the wireless network.
