摘要： PROBLEM TO BE SOLVED: To provide a call discriminating device which discriminates between a voice band call and an unlimited digital call, transmitted via a telephone line or an ISDN line using a simple constitution. SOLUTION: This device includes a decoding means A which decodes a service signal, a frequency characteristic detection means B which detects frequency characteristics of the decoded signal, and a call discriminating means C which discriminates whether the service signal is an unlimited digital call or a voice band call, on the basis of detected frequency characteristics. The frequency characteristic detection means B detects the frequency characteristics of the decoded signal in units of frames. The call discrimination means C includes a first discrimination part 11, which discriminates whether each frame is an unlimited digital frame on the basis of frequency characteristics and a second discrimination part 12, which discriminates its being an unlimited digital frame, that the proportion of the number of frames discriminated as being unlimited digital frames is higher than a prescribed value.

摘要： PROBLEM TO BE SOLVED: To improve the reliability of a sampling rate when measuring traffic. SOLUTION: A traffic measuring device includes a primary sampling part 41 for receiving packets acquired from a communication network and sampling them at a primary sampling rate, a buffer 42 for storing the primarily sampled packets, a secondary sampling part 43 for sampling the packets stored in the buffer 42 at a secondary sampling rate, and a statistical processing part 45 for receiving a count value of the packets acquired from the communication network and calculating the number of packets per unit time. The secondary sampling part 54 updates the secondary sampling rate on the basis of the number of packets per unit time and the number of packets stored in the buffer 42 so that a target sampling rate is kept.

摘要： PROBLEM TO BE SOLVED: To provide an illegal invasion preventing system so that a failured illegal invasion may not be noticed by an illegal invader while preventing the invasion by the invader to a normal data area. SOLUTION: When an access from the illegal invader is sensed, a converter 24 rewrites a destination [seiki] registered with an access request [http.../seiki/ doc] with a directory [otori] of a decoy data area 22. A communication application unit 23 accesses to the data area 22 designated by the access request. The converter 24 rewrites a response command [success/otori/doc] returned from the application unit 23 with contents [success/seiki/doc] of the effect as if the command is likewise accessed to a normal data area 21.

摘要： PROBLEM TO BE SOLVED: To provide a fire wall system to prevent unauthorized access to a normal server without making the lurker to be aware of the failure of the unauthorized access. SOLUTION: A host OS 202 operates on hardware 201 of an information management server 2. On the host OS 202, an emulator 203 operates together with various kinds of applications 204. On the emulator 203, a virtual normal server 21 and a virtual decoy server 22 operate as independent hardware servers and unique IP addresses are assigned to each of them. A normal access to the information management server 2 is led to the virtual normal server 21, while an unauthorized access is led to the virtual decoy server 22.
摘要翻译：要解决的问题：提供防火墙系统，以防止未经授权的访问正常服务器，而不使潜行者意识到未经授权的访问失败。解决方案：主机OS 202在信息管理服务器2的硬件201上操作。在主机OS 202上，仿真器203与各种应用204一起操作。在仿真器203上，虚拟正常服务器21和虚拟诱饵服务器 22作为独立的硬件服务器运行，并为每个服务器分配唯一的IP地址。对信息管理服务器2的正常访问被引导到虚拟正常服务器21，而未经授权的访问被引导到虚拟诱饵服务器22。
