| 摘 要： | 光纤通道仲裁环节点带宽分配,是以保证网络消息的实时传输为目标的.为解决网络消息集实时发送的问题,保证光纤通道仲裁环在强实时条件下的应用,依据实时系统中的周期任务模型,研究了一种带宽分配算法实现合理的带宽分配,保证各节点的消息均能实时传输,对其实时性能进行了理论分析,该方法在牺牲了少量的带宽利用率的基础上能保证所有消息的实时传输,最后例证了这种带宽分配算法优于其他算法.

| Abstract: | Bandwidth allocation of arbitrated loop of fibre channel is made to serve the purpose of real time transmission through the Internet. For real time communication and the application of arbitrated loop of fibre channel in the environment of real time communication, we have proposed a bandwidth allocation scheme based on the periodical task model in real time system. The properties of scheme in real time communication have been analyzed. The proposed scheme has been proved to be capable of ensuring real time communication with a little sacrifice on bandwidth and the algorithm on which the scheme is based is superior to other algorithms. |
