Communication apparatus for transmission protocol processing and reception protocol processing

摘要

According to one embodiment, a communication apparatus includes a reception protocol processing unit, a control information queue, and a transmission protocol processing unit. The reception protocol processing unit performs a protocol process using control information included in a received frame, acquires the control information from the received frame, and acquires data when the data is included in the frame. The control information queue stores control information including at least one of a reception window size of other communication apparatus, area information representing an area of data received by the other communication apparatus, the reception window size of the communication apparatus, and area information representing an area of data received by the communication apparatus. The transmission protocol processing unit performs a protocol process using the control information stored in the control information queue, generates a frame of a transmission target, and transmits the frame through the network interface unit.

主权项

1. A communication apparatus, comprising:
a network interface unit that performs transmission and reception of a frame with other communication apparatus via a network; a reception protocol processing unit that comprises first processing hardware, acquires control information by performing a protocol process related to the reception of the received frame and acquires data when the data is included in the received frame; a reception buffer that stores the data included in the received frame; a control information queue that stores a reception window size representing a data capacity of the reception buffer of the communication apparatus and the control information including area information representing an area of data to be next received by the communication apparatus, the reception window size and the area information associated with each other, the control information stored in a sequence that the reception protocol processing unit acquired the control information, and outputs the control information in the sequence that the control information is stored; and a transmission protocol processing unit that comprises second processing hardware, operates independently of and in parallel to the reception protocol processing unit, reads out the control information in the sequence that the control information queue outputs the control information, performs a protocol process related to the transmission using the control information read out in the sequence that the control information queue outputs the control information, generates a frame of a transmission target including the area information and the reception window size, and transmits the frame through the network interface unit.
