Data communication system for and method of avoiding computer network transmissions of excessive length

摘要

A data communication system includes in middleware a transmission task that transmits a message to a receiving host computer through a network, considering the transmission capability of the transmitting host computer and the receiving capability of the receiving host computer. This solves the problem in a conventional data communication system in which, if a host computer loses a token after acquiring it, operator stations and the like connected to a network are unable to send a message.
