When it comes to publish / subscribe ( p / s ) architectures, it can meet the integrate demand of the crcm well
而採用publish subscribe （ p s ）結構，能夠很好滿足鐵路管控系統集成的需求。 -
This essay analysis the data flows semantics in crcm system, compartmentalize them into 3 types : common data flow, operation data flow and control data flow
本文分析了鐵路管控系統中的數據流語義，將數據流類型抽象為公共基礎信息、業務信息和控制信息三類。 -
Ah the same time, there are various types of data flows in crcm system. different types of data flows have different communication demand, integrate system need to provide the qos communication service in wan
同時，鐵路管控系統中存在多種不同類型的數據流，不同類型數據流對通信的要求不同，集成系統應能提供廣域網環境下的qualityofservice （ qos ）通信服務。 -
At present, these subsystems are independent each other and can not share information with each other efficiently, which lower crcm system ' s efficiency, so it becomes very important to integrate these subsystems so as to improve railway ' s level of management and quality of service
當前，這些子系統彼此間相互獨立，難以進行有效的數據交互，降低了鐵路管控系統運行效率。因此，需要將這些子系統集成以提高鐵路管控系統的管理水平和服務質量。 -
Then the essay proposes a p / s based 2 - level architecture qos communication solution in crcm, gives the critical technologies of this solution include the establish of the multicast group dynamic reliable mechanism and the node ' s join and leave. at last, the essay simulates and compares the c / s integrate scheme and p / s scheme, analysis the main parameter of the model
然後針對鐵路管控系統，提出了一種採用p s兩級結構，廣域網環境下的qos通信解決方案，並給出了實現這一模型的幾個關鍵技術，包括：動態組播組的建立、可靠性機制、節點的加入和退出。 -
China railway control and management system ( crcm ) is a huge distributed system that constituted by serious subsystems. it depends on cooperation of subsystems that the whole crcm system functions normally. the degree of cooperation of these subsystems determines efficiency of the whole system ' s function to a certain degree
中國鐵路管控系統是由多個子系統構成的廣域分佈系統，其正常運營有賴于這些子系統的協同工作，子系統的整合程度的大小在一定程度上決定了整個系統運行效率的高低。
