摘要： A path selection method, an information processor, a network system, and a path selection program are provided which rapidly determine a path that has no loop when determining the path by using a control server to probabilistically select a pass node. A network having a plurality of paths from a source to a destination is controlled. A node forming the path is selected on the basis of a node-to-node transfer probability, and in the case where the selected node is a node that has already been passed through on the path, the transfer probability is reset such that the selection of the node is suppressed.

摘要： A route setup server has a storage unit, an IP routing unit and a flow management unit. A routing determination table indicating a router node assigned to an IP router among the plurality of nodes is stored in the storage unit. The IP routing unit has a software-based IP routing module having a same function as an IP router with respect to each router node. The flow management unit refers to the routing determination table to check whether or not a requestor node of a route setup request corresponds to any router node. The IP routing unit performs packet IP routing by using the software-based IP routing module associated with the corresponding router node to update a header of the packet. After that, the requestor node of the route setup request is updated to a destination node designated by a destination MAC address of the packet. Such the processing is repeated and thus the communication route is determined.

摘要： A route setup server has a storage unit a route designing unit. Next hop information indicating candidates of a next hop node for each node is stored in the storage unit. In response to a route setup request specifying a source node and a destination node of flow, the route designing designs a communication route between them. Specifically, the route designing unit has a next hop determination unit that executes “next hop determination processing” with reference to the next hop information. In the next hop determination processing, the next hop determination unit randomly selects one from the candidates of the next hop node regarding a target node and updates the target node to the selected one. The next hop determination unit determines the communication route one-hop by one-hop by initializing the target node to the source node and then repeating the next hop determination processing until the target node becomes the destination node.

摘要： In a terminal (1), when a connection is established, a packet generated by a data generating part (11) is outputted from a packet transmitting part (13). In the terminal (1), an ACK receiving part (14) receives an ACK packet transmitted as a receipt acknowledgement response to the foregoing transmitted packet. In the terminal (1), when the ACK packet is received, a cumulative band difference calculating part (18) calculates an accumulation or history of differences each between a target band and an actual output band. A target congestion window calculating part (20) defines, based on the cumulative band difference, a target congestion window. A congestion window limited-value calculating part (19) defines the upper limit of the congestion window. In the terminal (1), when the discarding of a packet is detected, it is not that the congestion window is reduced by one-half but that a smaller one of the target congestion window and the congestion window limited-value is used as a new congestion window.

摘要： A node apparatus includes ready queue lists, state variable storing section, state variable temporary storing section, and output control section. In the ready queue lists, the numbers of queues in a ready state for packet transmission are written. Each list manages the order in which the numbers were written. The state variable storing section holds state variables associated with all queues. The state variable temporary storing section temporarily stores only state variables associated with queues whose numbers fall within a predetermined range from the start of the list means and is smaller in data amount than the state variable storing section. The output control section transmits a packet from a queue having a number extracted from the start of the list and updates the state variable of the queue in the state variable temporary storing section. A method of transmitting packets is also disclosed.
