In the present disclosure, a network monitoring system is provided including an IP network monitoring unit () that monitors an IP network to which an IP device is connected; and a non-IP device monitoring unit () that monitors a non-IP device. It is possible to monitor both the IP network and the non-IP device in a system that includes the IP network including the IP device and the non-IP device.

Network monitoring system, network monitoring method, and program

To efficiently distribute data to a plurality of distribution destinations. According to the present disclosure, a system controller is provided controlling an IP switch that distributes data received from a device on a transmission side to a device on a reception side, the system controller building a plurality of virtual networks in the IP switch and causing data received by any of the virtual networks to be transmitted to respective distribution destinations connected to the virtual networks. With this configuration, data can be efficiently distributed to a plurality of distribution destinations.

System controller, controlling an IP switch including plural SDN switches

A decoding device that includes a decoding determination unit to determine a procedure of recovering and decoding missing packets in consideration of a packet missing pattern in data including a set of media packets and redundant packets generated by a two-dimensional XOR-based FEC encoding method. Further, a decoding unit executes the recovery of the missing packets according to the procedure determined by the decoding determination unit.

Receiving device and receiving method

[Object] To provide a communication control device configured to efficiently secure bands of an IP network in order to transmit data streams. [Solution] There is provided a communication control device including: a channel information acquisition unit configured to acquire, when AV streams are transmitted from a plurality of transmission apparatuses to one or more reception apparatuses on an IP network while being switched, all channel information from the transmission apparatuses to the reception apparatuses; a traffic calculation unit configured to calculate a maximum traffic generated in switching patterns of the transmission of the AV streams from the transmission apparatuses to the reception apparatuses, on the basis of the channel information acquired by the channel information acquisition unit; and a transmission band reservation unit configured to reserve a transmission band on the IP network, on the basis of the maximum traffic calculated by the traffic calculation unit.

Communication control device, communication control method, and communication system

There is provided a decoding device including a decoding determination unit that determines a procedure of recovering and decoding missing packets in consideration of a packet missing pattern in data including a set of media packets and redundant packets generated by a two-dimensional XOR-based forward error correction FEC encoding method, and a decoding unit that executes the recovery of the missing packets according to the procedure determined by the decoding determination unit.

[Object] To provide a new and improved information processing apparatus, information processing method, and program, capable of improving technology related to FEC for achieving a low delay transfer. [Solution] Provided is an information processing apparatus including: an acquisition unit which acquires a transfer bit rate; and a selection unit which selects an encoding system of forward error correction based on a comparison result between the transfer bit rate acquired by the acquisition unit and a threshold.

Information processing apparatus, information processing method, and program

[Object] To provide a new and improved information processing apparatus, information processing method, and program, capable of improving technology related to FEC for achieving low delay transfer. [Solution] Provided is an information processing apparatus including: an arrangement unit configured to arrange datagrams in a number of a predetermined matrix size or less in at least a portion of the matrix of the predetermined size, by repeating arrangement of the datagrams in order along a first direction according to a second direction; and a generation unit configured to generate a redundant datagram for forward error correction for each of the datagrams belonging to one row, and for each of the datagrams belonging to one column of the matrix arranged by the arrangement unit.
