Title: Network host tuning system
Inventor: YAJIMA TAKASHI
Filed: 1987-12-23
Abstract: PURPOSE:To ensure the response of an emergency transaction and to make the use job efficient by providing a means observing the number of transactions received by a host, its classification and reception time on a network. CONSTITUTION:The transaction observing system observes the number of transactions received by a network host, its classification and reception time, and stores them in a transaction priority order memory 11. A transaction priority decision system 9 reads the memory 11 to send the maximum response time of the emergency transaction to a network host operating state adjustment system 10. When the reply time of the emergency transaction is deteriorated in reference to a prescribed value or above, the system 10 reports it to the manager. Thus, the manager stops the input of a terminal equipment with low transaction priority.
