Abstract

A data receiving apparatus includes: a header analyzing unit that analyzes a header of a frame and outputs header information; a checksum judging unit that calculates and judges a checksum of the frame; a buffer unit that stores a data portion of the frame; a reading unit that reads connection information corresponding to the header information from a second storage unit; an identifying unit that identifies a write location for the data portion based on the connection information; a data writing unit that reads data from the buffer unit and starts writing the data to the identified write location in a first storage unit before the checksum is judged; and a writing unit that, if the judgment result is “pass,” writes the connection information updated based on the header information to the second storage unit while the data writing unit is writing.
