Navigation systems, methods, and programs acquire deviated point information regarding a deviated point where a vehicle traveling a set route has deviated the route, and acquire post-deviation travel history information regarding a travel history after a deviated vehicle has deviated the route at the deviated point. The systems, methods, and programs determine based on the post-deviation travel history information for each of the deviated vehicles whether the deviated vehicle has traveled along a reroute set after deviating the route at the deviated point, and judges whether a rate of the deviated vehicles which were determined as having traveled along the reroute is a first predetermined value or more. If the rate of the deviated vehicles which were determined as having traveled along the reroute is the first predetermined value or more, the systems, methods, and programs determine that guidance of the route is not appropriate.

Navigation device, navigation method, and program

A determination apparatus includes a processor and a storage unit. The processor acquires through a communication network a request packet transmitted from a client device to a server device group or a reply packet transmitted from the server device group to the client device. The server device group includes a first server device and one or more second server devices. The first server device is connected to the client device through the communication network. The storage unit stores configuration information for determining a source of the acquired reply packet. The processor determines whether the source of the acquired reply packet is the first server device or one of the second server devices on the basis of the configuration information stored in the storage unit.

Determination apparatus and determination method to analyze traffic between a client device and a server group

A server apparatus having a plurality of interfaces to each of which a network is connected, the server apparatus includes an application identification device for identifying an application program which is a source of a packet, on the basis of information in the packet, when the packet is sent to a network connected to any one of the plurality of interfaces, an interface designation device for designating one interface which is previously caused to correspond to an identified application program, among the plurality of interfaces, as a sending interface which is used in routing of the packet, and an routing device for sending the packet to a network connected to a designated interface.

Server apparatus, network access method, and computer program

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.

Streaming transmission method system, data processing apparatus and computer readable storage medium for making unwanted and malicious data unexecutable from voice or animation data streams

A method executed by a packet analysis apparatus for analyzing packets including voice packets and non-voice packets includes: capturing packets in a specific session; storing the captured packets in a storage; screening the stored packets to count up a receipt count of voice packets; determining whether packet loss has occurred in the specific session; and determining whether loss packets are voice packets in accordance with received packets adjacent to the loss packets to count up a loss count of voice packets when the packet loss has occurred.

Packet analysis apparatus and method thereof

An apparatus to collect information about network failure includes: a normal mode packet assembly unit to assemble a transmission packet from transmission data output from an application in a normal mode being a procedure used when a transmission process is performed by specified communication protocol; a special mode packet assembly unit to assemble the transmission packet from the transmission data in a special mode being a procedure in which a procedure for collecting failure information is embedded into the procedure used when a transmission process is performed by the specified communication protocol; a switching control unit to activate the normal mode packet assembly unit or the special mode packet assembly unit selectively; and a response analysis unit to collect failure information according to a behavior of the response to the transmission packet transmitted from the special mode packet assembly unit.

Device and method for collecting network failure information

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.

Packet capture system, packet capture method, information processing device, and storage medium

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 networkand a second communication networkwhich are connected by a first connection apparatussuch as a router, a determination is made as to whether the source of a packet passed through the second communication networkis the first connection apparatusor an apparatus other than the first connection apparatus. Packets whose respective sources are the first connection apparatusand packets whose respective sources are an apparatus other than the first connection apparatusare individually summarized. By comparing summarized results, the communication conditions are determined.

According to an aspect of the embodiments, a congestion detection method causes a computer to function as a congestion detection apparatus connectable to a network. Packets on the network are obtained and a packet loss is detected. A packet group made up of a series of packets based on the obtained packets is extracted. A packet loss in the packet group is detected and a position in the packet group where the packet loss occurred is detected. Whether congestion is occurring is judged based on the position of the packet loss in the packet group.
