  • Patent number: 7580410
    Abstract: The present invention relates to an extensible protocol processing system. The system of the invention is mounted between a host and a network, and is utilized to offload partial network protocol packets of the host. The protocol processing system comprises a microprocessor, a host interface device, a medium access controller, a message interface controller, a receiving device and a transmitting device. The system of the invention can provides better efficiency of the host for processing the offloaded partial network protocol packets. Besides, the function of the system of the invention can be extended by increasing the message and modifying the software or the firmware. Therefore, the system of the invention can be utilized to various applications, and has the easily extensible effects.

  • Patent number: 7447230
    Abstract: A protocol processing engine system, which is arranged between a host side and a media access control (MAC) layer to thus speed up data transmission. The system includes a host interface, a network media access control (MAC) interface, a receiving subsystem and a transmitting subsystem. The system uses the host interface to interface with the host side and the network MAC interface to interface with the network MAC layer. The receiving subsystem classifies a connection received from the network MAC layer into a priority connection, fast connection or slow connection based on a pre-stored information, and activates its respective hardware circuit based on the connection classified in order to speed up data transmission of the connection. The transmitting subsystem transmits a connection received from the host interface to the network MAC interface.
