Abstract

The invention relates to an information distribution system and an information management device.Under a condition that a communication section includes a data package net, end-to-end communicating time cannot be ensured to be constant because of changes of processing delay time in the device caused by crowd of the net, difference of device performance, or difference of processing priority level of each data package, etc. For a user signal (signal requesting for provision of services) input to a signal transport network, header information for transmission in the signal transport network is given at a portal edge of the signal transport network on the user side. The information given at this time includes a time stamp indicating the time of receiving the user signal by the edge. In a server on the service provider side, the time stamp is referred to, and services are provided for each user. Specifically, a response process schedule for each user is produced from the time stamp, and waiting time is reduced and a priority process is performed in accordance with the time of issuing the request by the user.

Description

technical field [0001] The present invention relates to a communication system and a communication management device constituting the communication system: based on a communication system including a communication network of an asynchronous data communication method in which data and control signals are transmitted and received in a packet format, users can use different communication systems respectively. In the communication system of the route access service providing server, the difference in the signal arrival time between users and the instability of the time required for communication, which is a characteristic of the best-effort communication method, are reduced by making the communication route different. Specifically, it relates to a communication system and a communication management device that unify information provision timing for each user enjoying a communication service from the viewpoint of service fairness. Furthermore, it relates to a communication system a...
