    摘要： A measurement method and communication system include a writing of a creation time upon a detection packet used for detecting a communication state of a network being created into the detection packet. The method includes obtaining a send time when the detection packet was sent and sending, to a receiving apparatus which receives the detection packet, as a notification, information regarding a time period from when the detection packet was created to when the detection packet was sent. The method includes measuring, in the receiving apparatus, a delay occurring in the network based on the detection packet and the information sent as the notification.

    摘要： Communication quality values such as delay times of packets transmitted and received within a packet network are measured, and a threshold value is calculated based on the measured communication quality values. Further, a management reference value is calculated based on the communication quality values of packets whose measured communication quality values are within a range based on the threshold value. A communication state is detected by comparing the measured communication quality values with the management reference value.

    摘要： The present invention enables accurate simulation of the state of communication over a communication network in which a communication channel of different communication characteristic is set for each protocol and session, such as a VoIP network built in a multi-vender environment, and evaluation of communication quality of communications between IP phones, etc. over a supposed communication network. A relay device for relaying packet communications between a plurality of communication devices is used, and the relay device sets a virtual processing unit as an initial process so that it corresponds to the packet transmission direction and/or attribute, based on the contents of a received packet specified by a control protocol, and relays communications of packets after the initial process, based on the packet loss rate and delay time distribution indicated by communication state information associated with the processing unit.

    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 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.
