对废弃话单进行有效管理,是保障通信系统计费可靠性的重要内容之一,然而对于废弃话单数据所呈现出的实时性、突发性等特征,现有的大数据处理模式并不能很好地应对.本文采用动态路由策略实现计算系统运行时的轻量级伸缩,应对废弃话单实时性和突发性带来的挑战.在此基础之上,本文给出了一种基于流式计算模型的废弃话单处理系统的实现,并通过实际数据验证了本文提出的动态路由策略在应对数据突发方面的有效性.

英文摘要：

Managing abandoned bills effectively is an important part to guarantee the accounting reliability of communication systems. However, for the distinctive features of the abandoned bills such as real time and burstiness, etc., the existing big data computing models can not deal with them well. In order to meet the challenges of real time and burstiness of abandoned bill system, this paper presents a dynamic routing strategy to realize the run time lightweight scaling of the computing system. On this basis, this paper gives an implementation of the abandoned bill system based on the stream computing model. Finally, the results demonstrate that the proposed dynamic routing strategy is an effective way on handling burstiness of data.
