Network and Shared Bus Access Control Method with Multiple Transfer Reservation Function

摘要

The present invention relates to a method and apparatus for transmitting and receiving data in a communication network having a transmission method in which a shared bus is used as a transmission medium and a plurality of nodes are connected and each node can transmit a frame in a given order without using a separate token frame The present invention relates to a communication network and a shared bus access control method having a multiplex transmission reservation function for maximizing a utilization rate of a bus when a node transmits a frame using a shared bus as a medium, In this paper, we propose a novel method to improve the efficiency of bus transmission. In this paper, we propose a novel method to increase the bus utilization rate. , Reduces the frame transmission delay between nodes connected to the network And to take advantage of, in particular, there is an effect suitable for the application, such as a switching system having a distributed control structure to communicate with each other tens or hundreds of processors within a limited short distance (several tens or hundreds of meters).
