METHOD AND DEVICE FOR GENERATION/MANAGEMENT OF PACKET INFORMATION IN NETWORK ENVIRONMENT

摘要

PROBLEM TO BE SOLVED: To provide a method and a device for generation/management of packet information in network environment, which implements mutual authentication between packets including generation/management for position locating information and history trace information in unit of a packet.

SOLUTION: In a computer network environment connected with communication lines such as radio and wireline, a packet travels among three points from the starting point of the time of transmitting event occurrence at a requesting computer for accepting the packet via the time of receiving event occurrence at a responding computer for sending out the packet to a finishing point of receiving event occurrence at the requesting computer. By applying a principle of prior occurrence that a timing of transmitting event occurrence at the requesting computer does not exist in future of a timing of receiving event occurrence at the responding computer, information for locating the position of the packet is generated by defining a logical time and a logical time duration determined uniquely with logical computation.
