To provide a terminal device capable of preventing user-unintended communication from being made. A communication control meanscontrols a packet transfer means for transmitting a packet. An instruction information giving meansgives instruction information indicating an instruction for the communication control meansto the communication control means. The communication control meanssends a flow detection notification that it detected a new flow to the instruction information giving meanswhen detecting the new flow. The instruction information giving meansdetermines whether to permit the flow to be communicated when receiving the flow detection notification. When determining to permit communication, the instruction information giving meansthen gives instruction information for instructing to transmit a packet of the flow in a path as an access network designated by the instruction information giving meansto the communication control means

Terminal device, terminal-device control method, and terminal-device control program

The communication terminal of the present invention, which is controlled by a control device, includes a first storage means for associating information identifying a packet with processing of the packet and storing it as an entry, a searching means for searching processing corresponding to a received packet from the first storage means, and an inquiry means for determining the control device of which is inquired, based on the entry corresponding to the received packet, the entry being stored in the first storage means, if the searched processing is the inquiry to the control device, and for performing the inquiry addressed to the determined control device.

Communication terminal, communication method, and program

Provided is a terminal device capable of recognizing communication traffic in a mobile network for each piece of application software. Communication control meanscontrols packet transfer means for transmitting a packet. Instruction information imparting meansimparts instruction information representing an instruction for the communication control meansto the communication control means. The communication control meansacquires statistical information including communication traffic for each flow from the packet transfer means and retains the statistical information along with information on application software which is a flow transmission source and information on an access network used for communication. The instruction information imparting meansacquires statistical information of each access network from the communication control meansfor each piece of application software.

There is provided a flow control device for controlling flow control rules defining processing contents per flow in a packet transfer device for processing packets belonging to a flow between a first communication device and a second communication device, which receives a packet reception notification indicating that the packet transfer device receives a packet from at least one of the first communication device and the second communication device from the packet transfer device, determines a flow control rule to be notified to the packet transfer device in response to the received packet reception notification, manages a packet reception notification reception time when the packet reception notification is received, and calculates a first round-trip transmission delay time between two devices among the first communication device, the second communication device, and the packet transfer device based on the packet reception notification reception times.

Flow control device, communication system, control method for flow control device, and program

To provide a communication terminal capable of selecting a communication interface corresponding to a communicable wireless network without the use of a route determination dedicated packet. A packet generation meansgenerates a packet based on data for receiving a service from a destination device. A control meansselects a communication interfacefrom among a plurality of communication interfaces, instructs a packet processing meansto send a packet generated by the packet generation meansto the communication interface, and when a response packet for the packet is not input until a timeout determination reference time, selects a different communication interfacefrom the communication interface, instructs the packet processing meansto send a copy of the packet to the communication interface

Communication terminal, communication method, and communication program

A communication apparatus comprises: a plurality of storage units adapted to store a process corresponding to a packet; a first unit that refers to at least one of the plurality of storage units and searches for a process corresponding to an incoming packet; and a second unit that queries, from among a plurality of control apparatuses, a control apparatus associated with a storage unit, in which the first unit has detected a predetermined condition, for a process corresponding to the incoming packet.

Communication apparatus, communication method, communication system and program

a network service using apparatus automatically performs a communication setting of a communicating terminal, when the network service using apparatus connects a network through the communicating terminal. A communicating terminal of the present invention contains a first communicating unit, a second communicating unit, a third communicating unit and a communication setting unit. The first communicating unit communicates with a network service providing apparatus through a network. The second communicating unit communicates with a network service using apparatus. The third communicating unit receives a request message of a communication path establishment, from the network service using apparatus. The communication setting unit performs the communication settings of the first communicating unit and the second communicating unit to establish a communication path through the first communicating unit and the second communicating unit based on the request message from the third communicating unit.
