Abstract

A communication apparatus comprises a generator configured to generate a header by a first method, and one or more computers for causing the apparatus to: obtain information of a window size from a communication partner apparatus; decide, based on the obtained information of the window size, a data size for a case of transmitting data to the communication partner apparatus; and if the decided data size exceeds a predetermined size, cause the generator to generate, by a first method, a header for data to be transmitted to the communication partner apparatus, and if the decided data size does not exceed the predetermined size, generate, by a second method different to the first method, a header for the data to be transmitted to the communication partner apparatus.

Claims14

Dependent claims

A communication apparatus comprising:

a generator configured to generate, by a first method, headers for a plurality of packets to be transmitted to a communication partner apparatus using common header information which is common to the packets;
and
one or more computers for causing the apparatus to:
obtain information of a window size from the communication partner apparatus;
decide, based on the obtained information of the window size, a data size of transmitting data to the communication partner apparatus;
calculate a checksum of data to be transmitted to the communication partner apparatus in a case where a predetermined condition is satisfied;
generate the common header information and cause the generator to generate, by the first method, the headers for the packets to be transmitted to the communication partner apparatus using the generated common header information in a case where the decided data size exceeds a predetermined size,
wherein in a case where a checksum of data to be transmitted to the communication partner apparatus calculated by the one or more computers exists, the generator is caused to generate the headers using the checksum calculated by the one or more computers, and
wherein in a case where a checksum of data to be transmitted to the communication partner apparatus calculated by the one or more computers does not exist, the generator is caused to calculate a checksum of data to be transmitted to the communication partner apparatus and generate the headers using the checksum calculated by the generator;
and
generate, by a second method different from the first method, a header for a packet to be transmitted to the communication partner apparatus without generating the common header information in a case where the decided data size does not exceed the predetermined size.
