Title: Multiple address communication system
Inventor: SOEDA HARUTO
IPC: H04L12/18
Filed: 1994-03-18
Abstract: PURPOSE:To prevent reply data from being sent to a communication channel centralizingly by allowing only a designated reply computer to return reply data with respect to multiple address communication data. CONSTITUTION:A transmission section 22 of a multiple address communication transmission computer decides a reply computer designated to return a reply to multiple address communication data among multiple address communication reception computers and sends multiple address communication data obtained by adding a serial number and a reply computer name to a data text not sent yet stored in a storage section 21. Upon the receipt of the multiple address communication data, the reply computer generates reply data and sends the data to a sender computer. A management section 25 of the sender computer commands transmission of succeeding multiple address communication when data not yet sent are stored in the storage section 21. The reply computer returns a re-transmission request of multiple address communication data whose serial number is missing when the serial numbers of the received multiple address communication are not consecutive. Receiver computers other than the reply computer returns a retransmission request of the multiple address communication data of a missing number for a prescribed limit time when the missing serial number is detected.
