Abstract
A packet according to a secure protocol over a high-speed protocol has a small size header. A reception system estimates a packet number which is used in processing of a packet having a small size header on the basis of information indicating a packet number of a received packet. The header of each of one or more packets among N packets (where N is an integer of two or more) is a small size header, which is either a first header having one part of the packet number of the packet or a second header without the packet number of the packet. When the small size header is the first header, the header of each of the N packets is the first header. When the small size header is the second header, the header of each of the packets other than one packet among the N packets is the second header.
