Abstract
The worst case for real-time transmission on Fibre Channel-Arbitrated Loop(FC-AL) is complemented when considering the priorities of messages. Two conditions to guarantee the deadlines of each message in the message set are re-defined. The concept of the fairness load rate under the worst case is presented so that the above two conditions can be concluded as: the fairness load rate of each message under the worst case should not be greater than 1. This conclusion exposes the essential relationship between the real-time transmission and load rate. Thinking about the increasing cost of protocols and the delay of physical layer due to the segmentation of messages, a dedicated algorithm of bandwidth allocation based on the principle to minimize the total load rate of the network is given. A synthetic message set is studied to prove the validity of this method.关键词
