Abstract: A data-storing-terminal counting unit counts the number of communication terminals in which each of a number of data are stored. Based on the results of the counts, a communication terminal count estimation unit estimates the number of communication terminals that will transmit data with the same timing. An adjustment reference value calculation unit computes an adjustment reference value for constraining the number of communication terminals estimated by the communication terminal count estimation unit to be less than or equal to a preset allowable number. On the basis of the adjustment reference value computed by the adjustment reference value calculation unit, a determination unit determines whether or not to permit transmission of data stored by a storing means. If the determination unit permits the transmission of said data, a data transmission unit transmits the data to a communication terminal in which said data is not stored.

A power network system has a plurality of power routers (1-7), power transmission lines (100-111) connecting the power routers, a controller (8), a communication network (10), and communication lines (11). The controller (8) obtains a reception electric energy and a transmission electric energy in the power routers (1-7), detects a failure due to a fault in, for example, the power router (4), and searches for an alternate route to solve deficiency/excess power caused by the failure occurrence. Concretely, an alternate route is searched while following a power router having excessive power as a root node by a breadth first search, and transmitting the deficiency/excess power and an allowable power transmission capacity in each of the power routers to an adjacent power router.

Abstract: A packet retransmission control system has: a network control block configured to perform packet retransmission control in an upper layer; and a packet retransmission control block configured to perform packet retransmission control with a shorter retransmission timeout than the upper layer in a lower layer that is lower than the upper layer. If the network control block receives a duplicate acknowledge packet being an acknowledge packet notifying a same sequence number for a predetermined number of times, the network control block performs packet retransmission. The packet retransmission control block determines whether or not retransmission of a same packet is performed earlier in the upper layer than in the lower layer. If retransmission of the same packet is performed earlier in the upper layer than in the lower layer, the packet retransmission control block prohibits retransmission of the same packet in the lower layer.

The disorder packet is one of the received packets which is received in an order different from a transmission order of the packets. The communication flow information identifies the plurality of communication flows.

Abstract: Disclosed is a system in which Aan NFA conversion meansunit 21, receives the number of simultaneous/parallel processing characters from an input device 1 and, using a one-character transition finite automaton description matrix stored in an NFA description matrix storage unit 31 and a description matrix which is stored in an NFA conversion result matrix storage unit 32 as an intermediate conversion result, converts the finite automaton to a finite automaton whose transition condition is described in the number of characters subjected to simultaneous/parallel processing.
