实时CORBA优先级波段划分的研究及算法实现

Study on Priority Banded Connections in Real-Time CORBA

实时CORBA是通用CORBA的一个扩展 ,首先对实时CORBA系统的传输机制进行了一定的分析并给出了相关的仿真试验 ,在此基础之上提出了计算实时CORBA系统所需波段数的试探性算法 ,以及基于负载平衡的波段优先级范围划分算法 ,并进一步提出了改进的加权算法 .测试结果表明算法能在兼顾到周期和优先级因素的基础上 ,对实时CORBA系统的优先级波段连接进行合理的优先级划分 .

Real-time CORBA specification is an extension of CORBA specification. This paper first introduces the priority banded connections in the real-time CORBA specification, then gives an algorithm to determine the amount of priority banded connections and an algorithm to compute the scope of each priority banded connection. Also an improved algorithm is given. Finally, some experiments are done to prove the algorithms' rationality.
