Study on bandwidth allocation optimization of FF acyclic communication

In process control application of FF, in order to ensure that acyclic communication with critical time constraints is met, the bandwidth proportion allocated to acyclic communication is oversized, which lead to waste of bandwidth. For the sake of improving bandwidth availability of FF, in this paper, based on priority mechanism, bandwidth allocation of FF is analyzed, and two bandwidth allocation strategies are researched and compared in performance. Finally, optimization strategy of FF acyclic communication is proposed based on generalization of preceding results.
