1. A method for analyzing network packets, comprising: receiving, using a network processor, a network packet having a packet header including address and control information; extracting, using the network processor, a set of bytes from the packet header, wherein the set of bytes is selected based on usage of the network processor within a network structure; deriving, using the network processor, from the set of bytes a set of input bits for generating a hash code; and generating, using the network processor, the hash code using the input bits.
