Abstract: A communication apparatus receiving data included in a content from a transmitting apparatus by using a logical connection with the transmitting apparatus includes a notifying unit configured to notify the transmitting apparatus of information regarding an amount of data that the communication apparatus permits transmission of data using the logical connection from the transmitting apparatus to the communication apparatus, a receiving unit configured to receive data included in the content transmitted from the transmitting apparatus in response to the notification performed by the notifying unit, and a control unit configured to control so as to inhibit the notification by the notifying unit until the logical connection is disconnected in a case where the amount of data not received by the receiving unit of the data included in the content is smaller than a predetermined value.

Abstract: A communication apparatus stores data to a storage unit, receives a first request signal from a first other communication apparatus by a wireless communication that complies with a first communication method, determines, if the first request signal is received, whether or not target data to be transmitted is stored in the storage unit, performs, if the target data is determined to be stored in the storage unit, connection processing by using a wireless communication that complies with a second communication method different from the first communication method, and transmits, if the connection processing is performed, target data by using the wireless communication that complies with the second communication method, wherein if the target data is determined to not be stored in the storage unit, the connection processing is not performed.

Abstract: A communication apparatus switches between a first operation mode and a second operation mode lower than the first operation mode in power consumption, each of which is an operation mode of the communication apparatus, determines whether it is possible to switch the operation mode of the communication apparatus from the second operation mode to the first operation mode in response to receiving a predetermined packet from another communication apparatus. If the communication apparatus determines that it is possible to switch from the second operation mode to the first operation mode in response to receiving the predetermined packet, it switches the operation mode of the communication apparatus from the first operation mode to the second operation mode.

Abstract: A communication apparatus establishes a connection and at least one stream for communication with another communication apparatus, determines a first window size relating to a buffer size for the connection and a second window size relating to a buffer size for the at least one stream based on communication information about communication between the communication apparatus and the other communication apparatus, and transmits to the other communication apparatus the first and second WINDOW_UPDATE frames.

Abstract: A communication apparatus transmits identification information for identifying a push message to be transmitted to the communication apparatus to a relay apparatus by using the first transmission unit, receives, from the relay apparatus, a push message transmitted by the relay apparatus after the first transmission unit transmits the identification information to the relay apparatus, and performs a process for switching the operation mode of the communication apparatus from the first operation mode to the second operation mode lower than the first operation mode in power consumption after the first transmission unit transmits the identification information to the relay apparatus.

Abstract: A communication apparatus for communicating a push message with another communication apparatus, comprises an obtaining unit configured to obtain time information to synchronize a period in which processing related to the push message is possible with the other communication apparatus; and a communication unit configured to execute, during a period of processing in which the processing related to the push message is possible and which is specified based on the time information obtained by the obtaining unit, push message communication with the other communication apparatus.

Abstract: When, in communication using a protocol in which at least two streams are established over a connection, a notification that a new stream will be reserved is made, a process for preventing a non-communication state exceeding a predetermined amount of time is initiated and a frame is sent at least every predetermined amount of time in the case where there is no other stream currently reserved, whereas processing is ended without initiating the stated process in the case where there is already a reserved stream.

Abstract: A communication apparatus includes a first acquisition unit and a determination unit. The first acquisition unit acquires a number of messages to be transmitted to another communication apparatus. The determination unit determines, based on the number of messages acquired by the first acquisition unit, a communication protocol to be used for a communication with the another communication apparatus from a plurality of communication protocols.

Abstract: A novel hydrocarbonylation, i.e., decarbonylation in the presence of hydrogen, is disclosed. By applying hydrodecarbonylation to a series of reactions, monocyclic aromatic hydrocarbons such as benzene can be obtained in high yield from polycyclic aromatic hydrocarbons or heavy oils containing such materials. Thus, the present invention provides a method of effective utilization of carbon sources.
