Abstract
A network having a plurality of switch points, each switch point having both a main multi-stage pipeline and a look-ahead pipeline between input ports and output ports of the plurality of switch points is described. The look-ahead pipeline has fewer pipeline stages than the main multi-stage pipeline. Look-ahead information and corresponding packet are received at an input port. A first stage look-ahead request is generated from the look-ahead information. A second stage look-ahead request is generated in response to the first stage look-ahead request being not granted. And in response to the second stage look-ahead request being granted, transmitting a packet through the switch point using the look-ahead pipeline.
