On a Characteristic of Data Transmission In Bus Network

M. Ooki
Abstract—Bus network is a primary topology in local area network and the network had a problem of data collision on the bus which influenced the efficiency of data transmission. Recently, using switching-hub that establishes a link from a sending station to a receiving station, the number of data collisions extremely decreased. However, in the case that the data buffer of a receiving station is full or the receiving station is sending or receiving data, a sending station has to wait for sending data. This waiting time (stand-by time) influences an efficiency of data transmission. In this paper, a characteristic of data transmission with the stand-by time in bus network is clarified. Taking note of one station with a sending data buffer, the link probability that the link from the station to a receiving station will be established is defined as constant. The station connected to the bus is modeled as a queue with stand-by time, and then state equations of the probability of the number of waiting data at the ready time of sending are expressed. From the equations, probabilities of the number of waiting data, mean of the number of waiting data in the sending buffer and mean waiting time which is the time from the data arrival time at the sending buffer to the beginning time of sending are derived. The calculated values are illustrated with the link probabilities in several cases, and then the influences of the link probability to data transmission are shown.

Index Terms—Bus network, link probability, the number of waiting data, mean waiting time.
