Patent attributes
A node includes a switch controller and an optical module configured to receive optical signals from at least one other node in a network. It is determined from an electrical signal for a first optical signal whether to process data from one or more subsequent optical signals or to route the one or more subsequent optical signals out of the of the node without processing data from the one or more subsequent optical signals. According to another aspect, a first optical signal is transmitted from a first node in a data processing system to a second node in the data processing system. Based on evaluation at the second node, it is determined whether to route one or more subsequent optical signals to a third node without processing data from the one or more subsequent optical signals at the second node.
