Abstract

See full text

A method may include receiving a first packet; determining, in a first processor, whether the first packet meets a criterion to be forwarded to a destination indicated in the first packet; receiving a second packet; determining whether the second packet is of a type for changing the criterion and sending the second packet to a second processor if the second packets is of the type for changing the criterion; receiving instructions, based on the second packet sent to the second processor, to change the criterion; and changing the criterion.
