摘要： The invention provides a packet communication system, a packet communication method, a transmission apparatus, and a storage medium having stored therein a computer program used in the transmission apparatus. The transmission apparatus generates a random number, sets a packet transmission interval based on the generated random number, and transmits a packet in the packet transmission interval. In addition, the transmission apparatus transmits a load density detection packet for detecting traffic load density, receives from a reception apparatus transmission quality information about the delay and/or loss rate of the load density detection packet, and calculates, based on the received transmission quality information, a time at which delay is smallest in a packet transmission interval and/or a time at which a loss rate is lowest in the packet transmission interval. The transmission apparatus sets the calculated time as a packet transmission start time and starts packet transmission.

摘要： A computer-readable recording medium recording a program capable of accurately analyzing the cause of a performance fault at the very end point of a client system, server system, etc. Outgoing and incoming packets are captured during execution of a communication application to measure a round trip time, and a communication window size of the transmitting source is estimated based on the captured incoming packets. A throughput estimate is calculated from the round trip time and the communication window size, and the estimated value and actual measured value of the throughput are displayed on, for example, a display, together with various other communication parameters including the communication window size and the round trip time, whereby the cause of a performance fault can be accurately located by quantitative analysis.

摘要： A data processing apparatus edits an actual data portion excluding a header from data transmitted by streaming transmission from a first information processing apparatus after start of streaming transmission. The data processing apparatus transmits edited actual data portion and header to a second information processing apparatus by streaming transmission. The second information processing apparatus reproduces the voice data or the animation data transmitted by streaming transmission. The actual data portion is edited so that the voice data or the animation data to be transmitted may be reproducible in the second information processing apparatus, and so that a program may become unexecutable even if it would be transmitted to the second information processing apparatus. Even if the voice data or the animation data transmitted from the first information processing apparatus by streaming transmission would be deteriorated, an executable virus program does not transmitted to the second information processing apparatus, thereby that makes it possible to realize the streaming transmission method which can realize simple and high security.

摘要： A sharing control processing unit controls sharing of capture of packets among measuring devices connected to the same network. An aggregating unit collects the captured packets. Each measuring device notifies the sharing control processing unit of a state about its capture. The sharing control processing unit determines which measuring device is to start/stop the capture, according to a predetermined rule and the notified state. When determining that the capture is to be switched from a first measuring device to a second measuring device, the sharing control processing unit instructs the second measuring device to start the capture. After receiving a notification that the second measuring device has actually captured a packet(s), the sharing control processing unit instructs the first measuring device to stop the capture. The aggregating unit identifies a duplicate packet(s) double captured by the first and second measuring devices.
