1. A method of performing transformation adapter functions in a network element, the method comprising the computer-implemented steps of:

  • determining, at the network element, a first application layer message that is contained in one or more payload portions of one or more data packets, wherein the first application layer message conforms to a first application layer protocol;

    determining the first application layer protocol;

    selecting, based on the first application layer protocol, a first adapter from among a plurality of adapters that are accessible to the network element; and

    wherein the first application layer protocol is one of a plurality of different application layer protocols and wherein each of the adapters is configured to transform a different one of the plurality of application layer protocols into a canonical protocol;

    providing the first application layer message as input to the first adapter, wherein the first adapter converts the first application layer message into a second message that does not conform to the first application layer protocol.
