Abstract
In one embodiment, a method, comprising producing a first policy vector based on a first portion of a data packet received at a multi-stage switch. The method also includes producing a second policy vector based on a second portion of the data packet different than the first portion of the data packet. A third policy vector is produced based on a combination of at least the first policy vector and at least the second policy vector. The third policy vector including a combination of bit values configured to trigger an element at the multi-stage switch to process the data packet.
