Abstract
A self-configuring distributed switch is disclosed. The switch comprises a channel switch core connected by a plurality of channels to a plurality of high-capacity data switch modules. A global controller selects paths through the channel switch core and reconfigures the paths in response to dynamic changes in data traffic loads. Propagation delays between the data switch modules and the channel switch core are coordinated to keep reconfiguration guard time minimized. The advantage is a very high-capacity, load-adaptive, self-configuring switch that can be geographically distributed to serve a large geographical area.
