tune request meaning in English

调音

5 . in the industrial control application , information transmitted on control layer network has become more and more complex , requiring that communication network should satisfy real tune request diversity of information . to satisfy this requirement , a mixed schedule algorithm on switch ethernet is put forward based on information classification . according to information types , the algorithm takes different schedule algorithm which include setting priority level , modified rm schedule algorithm on hard real time information , priority level upgrade schedule algorithm
针对这一问题，通过研究交换式以太网的实时调度问题和过程监控层信息的实时性要求，对信息进行了分类，提出了基于交换式以太网的混合调度算法，对不同类型的信息采取不同的调度算法，在优先级分配上，对各类信息设置不同的优先级;对硬实时信息，提出了改进的rm调度算法;对硬实时信息和软实时信息的协调，提出了优先级提升调度算法。
