Abstract:
1. A network processing apparatus, said apparatus comprising: a host media access controller (HM) subunit for communicating with a host computer; a sequence processor (SP) subunit for performing decapsulations, decryption, authentication, and checksum operations on one or more data frames; an address translation (AT) subunit for communicating with said sequence processor subunit and performing routing and stateful firewall functions on one or more data frames; and a media access controller interface (MI) subunit configured to preface the one or more data frames with canonical header information so that the SP and the AT do not have to parse other header information associated with the one or more data frames, wherein the network processing apparatus is configured to transmit and receive data frames to and from one or more auxiliary processing units using internet protocols without involving a host processor.
