The dissemination of a Time Reference throughout a network is useful in the operation of a switched digital communication network. The Time Reference Distribution Method (TRD) is a hierarchical scheme of dynamically allocating information paths for the flow of such reference information from the master node to all the other nodes in the network. This report is a detailed study of the feasibility of using a currently available microprocessor at each node to implement the TRD algorithm. The characteristics of some current microprocessors are studied. Three different implementation algorithms are developed for the dynamic allocation process. A sample design of microprocessor system for one of the algorithms is presented. A estimate of the computing power needed is made and implementation problems are discussed. (Author)
