1. A method, comprising: producing a first policy vector based on a first portion of a data packet received at a multi-stage switch; producing a second policy vector based on a second portion of the data packet different than the first portion of the data packet; and producing a third policy vector 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, each of the first policy vector and the second policy vector is a decompressed policy vector defined based on a compressed policy vector retrieved from a policy vector database.
