CONNECTION CONTROL SYSTEM

摘要

PURPOSE:To avoid deterioration of the processing performance for conflict queuing of connection requests by keeping the answers waiting to other connection requests produced during reconnection to an optional host device and then selecting effectively the connection requests kept waiting. CONSTITUTION:Four connection ports 31(0)-31(3) are provided and a connection unable answer preventing parts 214a-214d have FF constitutions. the signals 4a-4d are produced from OR 213a-213d when the reconnection is secured among the ports excepting those ports 31(0)-31(3). When the signals 4a-4d are turned on, the corresponding parts 214a-214d are set. The progress of a connection unable answer sequence is stopped by the signals 8a-8d delivered from the parts 214a-214d even in case a connection request is produced for ports 31(0)-31(3) corresponding to those set parts 214a-214d. As a result, the answer is prevented to the connection request and therefore the deterioration can be minimized for the the processing performance of the conflict queuing.
