    • A dynamic optimum design is realized to dynamically adopt a multipath route according to a reception situation of the traffic flow of each terminal, to select a splitting method such as a copy and division at a split position according to the situation of the network, and to minimize the cost imposed on the network. Specifically, in a control unit which sets a route of the traffic flow dynamically to an optional node on a network, monitors the reception quality of the communication traffic flow on the network to calculate a split position of the traffic flow, the splitting method such as copy and division, and a split route in order to attempt optimization based on maximization and stabilization of reception quality. In response to an instruction from the control unit, the traffic flow is dynamically split onto a plurality of routes by the splitting method such as an identical copy, a partial copy, a flow base division and a random division, in one or a plurality of optional nodes of nodes through which the communication traffic passes, and the traffic flow is restored on a reception side.
    • 实现动态最优设计,根据每个终端的业务流的接收情况来动态地采用多路径路由,根据网络的情况选择分割位置的复制和划分等分割方法,并且 最小化网络上的成本。 具体地说,在将业务流的路由动态设定为网络中的可选节点的控制单元中,监视网络上的通信业务流的接收质量,计算出业务流的分离位置,分割方法如 复制和分割,以及分裂路由,以便基于接收质量的最大化和稳定来尝试优化。 响应于来自控制单元的指令,业务流被动态地分割到多个路由,通过分割方法,例如相同的拷贝,部分拷贝,流分类划分和随机划分,在一个或多个 节点的可选节点,通信业务通过的节点,并且在接收侧恢复业务流。

    • When a packet transfer equipment receives a packet, it extracts several types of information contained in the received packet such as the destination IP address and the destination port number and, using the extracted information as the key, inquires of a packet transfer method resolution server about the information related to the packet transfer method. The server keeps the correspondences between several types of information contained in the packet and one or more type of information related to the packet transfer method in the database and, in response to the inquiry from the packet transfer equipment, replies one or more type of information related to the packet transfer method. The packet transfer equipment rewrites several types of information such as the destination IP address and the destination port number according to one or more type of information obtained and transfers the received packet.

    • A DNS Proxy unit (A12a) holds the domain name of an encrypted communication target node in a CUG setting table (A125a), intercepts a name resolution request for a communication partner node output from an application (A11x) to a DNS server (B1a), determines by looking up the CUG setting table (A125a) whether the communication partner is an encrypted communication target node, and if the communication partner is an encrypted communication target node, registers the IP address of the name-resolved communication partner in an encrypted communication path setting table (A142a). A data packet sent from the application (A11x) to the IP address is intercepted by a data transmission/reception unit (A14a). A data packet to an IP address registered in the encrypted communication path setting table (A142a) is encrypted by a communication encryption unit (A141a) and transmitted to the communication partner. In this way, in executing encrypted communication with a plurality of communication partners by using a communication encryption function provided by an OS, setting of the encrypted communication target node can be done by using a domain name.

    • In a feedback amplifier circuit, a first switching device executes an auto-zero operation by inputting a signal outputted from an amplifier to an input terminal of the amplifier during an auto-zero operation interval prior to an amplification interval. A first capacitor accumulates and holds an offset voltage at the output terminal of the amplifier during the auto-zero operation interval, and cancels an offset voltage at the input terminal of the amplifier by an accumulated and held offset voltage during an amplification interval subsequent to the auto-zero operation interval. A second switching device grounds the feedback point of the feedback circuit during the auto-zero operation interval. A second capacitor blocks a DC voltage, and accumulates and holds an offset voltage at an output terminal of the amplifier, and cancels an offset voltage at an input terminal of the amplifier by the accumulated and held offset voltage during an amplification interval.
