摘要： This present invention provides a traffic control system which adapts a P2P traffic to the circuit capacity and topology of a physical network. In a traffic control portion, a correspondent node identifying portion monitors the header of a packet exchanged by each P2P traffic and identifies the attribute of a correspondent node. A monitoring object extracting portion extracts a P2P connection based on the identification result. A traffic amount measuring portion obtains the total amount of each P2P traffic which is a monitoring object. A connection selecting portion selects a connection which should be shut down based on the total traffic amount. A filter portion shuts down the shut-down object connection selected by the connection selecting portion of the traffic monitoring portion.

摘要： Data of traffic with long-range dependence characteristics is generated by a host terminal and transferred to a memory arranged on a board. The memory stores the traffic data comprising at least one of the number of IP packets output per unit time and total number of bytes, a set value of each parameter of the generated IP packets (i.e., packet length table) and an IP address table. A packet generation section refers to the data in the memory to generate traffic with long-range dependence characteristics at a speed corresponding to a high-speed network. As a result, the behavior of the network at the time of application of the load can be measured before the actual use of the network. According to the present invention, a traffic generation apparatus that can supply the actual network with a load close to the real traffic can be provided.
摘要翻译：具有长距离依赖特性的业务的数据由主机终端产生并传送到布置在电路板上的存储器。存储器存储包括每单位时间输出的IP分组数量和总字节数，生成的IP分组的每个参数的设定值（即，分组长度表）和IP地址表中的至少一个的业务数据。分组产生部分参考存储器中的数据，以对应于高速网络的速度产生具有长范围依赖特性的业务。因此，在实际使用网络之前可以测量网络在应用负载时的行为。根据本发明，可以提供能够向实际网络提供接近实际业务的负载的业务量生成装置。

摘要： The present invention detects a failure location of network in the Internet. A pair of networks consists of an access network and an Internet service provider network, and a route consists of a source pair of networks and a destination pair of networks. The quality information values are inputted to elements in a matrix that all pairs of networks are put in same order as rows (or columns) of source pairs of networks and columns (or rows) of destination pairs of networks. If inferior quality values in the matrix line up in the row (or column), a failure is determined in a destination (or a source) pair of networks in column side (or row side) corresponding to a row (or a column). If inferior quality values line up in a slanting direction, a failure is determined in a route between the Internet service provider networks indicated to the slanting direction.

摘要： In order to distribute multicast packets, using different multicast addresses and avoiding fault points, a backup server is installed close to a master and converts backup multicast packets and sends them as master multicast packets to the client. At this time, backup multicast packets are delayed and sent while the delay is determined from an allowable retransmission time, a one-direction delay to the client, a time required to detect linkage problems, and a time required to establish backup paths and so on.

摘要： A communication system includes a probe transmission server 3 which transmits at fixed intervals of time a probe multicast packet distributed along the same path as a main multicast packet, a delay insertion server 5 which appends the same fixed delay time to each of the main multicast packet and the probe multicast packet, a backup server 2 which generates synchronism and delay backup multicast packets from the main multicast packet and transmits them, and a communication control device 7 which determines the communication of the main multicast packet based on a reception interval of the probe multicast packet, generates a backup main multicast packet from the backup multicast packet when a communication break is detected, and transmits it. The communication system, upon implementing a broadcast-type multicast service, enhances compensation of communication breaks when detecting and recovering from a fault in an IP network, and reduces the network traffic.

摘要： A TCP gateway terminates TCP flow control and retransmission control of TCP packets which are input from a transmitter side terminal, in place of a receiver side terminal. Also, the TCP gateway transfers the packet to the TCP gateway which is located on the opposite side, by using selective retransmission procedures in a data link layer using SSCOP and by using peculiar flow control procedures. In addition, the TCP gateway provides the process of transferring the packet to the receiver side terminal in accordance with the TCP process procedures in place of the transmitter side terminal, to a plurality of TCP connections simultaneously.
