We describe an experimental message management system which consists of three modules: the message manager, the message filter, and the adaptive protocol handler. The message manager utilizes a relational database for message management. To control message traffic in an office information system, the message filter determines whether the full message is to be sent, or a short alert message should be sent. Message filter and linguistic filter design algorithms are presented. The adaptive message protocol handler can transmit the short message several times to increase message reliability, and the desirable number of transmissions is determined adaptively. Comparison with usual protocols indicates the superiority of the adaptive protocol under noisy channel conditions. The experimental message management system was implemented using the C language on a PDP 11/70 minicomputer running under the Unix operating system.
