The problem of guaranteeing real time message transmission in LTPB network, linear token passing bus, has been studied. Bandwidth allocation for LTPB aims at real time message transmission, and the key parameter, the minimum amount of time used for real time message transmission in unit time, is an important factor to the property and validity of the bandwidth allocation. Having found out a defect in current real time performance analysis method, we propose a concept of “the worst case situation”, develop a reasonable model, get an important result in real time performance analysis for LTPB network, and establish the analytic foundation to seek the better bandwidth allocation scheme.
