摘要： A communication conditions determination method, a communication conditions determination system, and a determination apparatus are provided in which the conditions of communication which is performed through a plurality of communication networks are determined without setting up a special apparatus on all the communication networks and without increasing the existing traffic. In a first communication network 100 and a second communication network 200 which are connected by a first connection apparatus 1 such as a router, a determination is made as to whether the source of a packet passed through the second communication network 200 is the first connection apparatus 1 or an apparatus other than the first connection apparatus 1. Packets whose respective sources are the first connection apparatus 1 and packets whose respective sources are an apparatus other than the first connection apparatus 1 are individually summarized. By comparing summarized results, the communication conditions are determined.

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： 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.
