摘要： A method of conducting a connectionless communication in a network communication system including a client, a server, and a plurality of proxy servers which are disposed on a transmission path between the client and server. The communication is accomplished by use of specification of a communication address thereof and a port number dynamically assigned by the computer. (a) The server transmits own communication address and own port number to the client. (b) The client transmits own communication address and own port number as well as the communication address and port number of the server to a first adjacent proxy server computer. (c) The N-th (N≧1) proxy server transmits own communication address and own server side port number as well as the communication address and the port number of the server to an (N+1)-st proxy server. (d) step (e) is repeatedly executed by incrementally increasing N until the (N+1)-th proxy server becomes a terminal proxy server. (e) The terminal proxy server transmits its own communication address and its server and client side port numbers to the N-th proxy server. (f) The N-th proxy server sends own communication address and own client side port number and the communication address and the server side port number of the terminal proxy server to the (N−1)-th proxy server when N≧2 or the client when N=1. (g) step (f) is repeatedly executed by incrementally increasing N until N becomes one. (h) The client transmits a communication address and a server side port number of the proxy server to the server. (i) The connectionless communication is commenced after all computers acquire a communication address and an associated port number of each of the computers adjacent thereto.

摘要： An optical information recording medium comprising a thin plastic substrate of 0.6 mm or thinner, wherein the substrate is protected against strain without being limited by a film structure and a film formation condition. A single-layer or multilayer thin film (70) is formed on a plastic disk-like substrate having a center hole (10). This thin film (70) has a strain relief area (72) inside a recording area (71). This strain relief area (72) is formed by setting an outer diameter of an undeposited inner portion (5) to a value satisfying the following formula (1), for example: A0≦AX≦−0.172P+0.163 where A0: diameter of center hole, AX: outer diameter of undeposited inner portion, P: total strain occurring in thin film when film depositing.

摘要： An analysis unit which effectively detects incidents on the basis of events detected by a security unit such as an intrusion detection system (IDS) or a firewall (FW) installed in a network stores statistical information that is frequency-distributed information of event information obtained from the collection unit, frequency component information obtained by frequency-analyzing the statistical information and the result obtained by making analysis on the basis of the frequency component. The collection unit collects and normalizes event log information outputted by IDS or FW to be stored in an event database (DB). An alert notification unit includes an alert database (DB) for storing an alert instruction transmitted from the analysis unit and an alert notification destination and reports occurrence of incidents to a manager or the like in accordance with the instruction.
