Abstract

A communication processing device includes a processing unit configured to process a network layer of a communication frame received from a transmission line. A header part of the network layer contains extension header presence/absence information that indicates whether the header part has an extension header part for defining header information different from header information defined by a standard header part standardly included in the header part. The processing unit includes: a first processing unit for processing the standard header part; a second processing unit for, if the header part has one or more extension header parts, individually processing the one or more extension header parts of the header part; and a determination unit for determining the presence or absence of an i+1th extension header part, based on the extension header presence/absence information contained in an i-th extension header part, where i is an integer of 1 or more.
