Abstract: Because of the great quantity of network traffic data, the first problem for network traffic engineering is how to store traffic data and retrieve these data efficiently. This paper presents a design of how to store and retrieve NetFlow data in distributed multi-level directory. An optimization blueprint is discussed whose objective is to store and retrieve NetFlow data efficiently. This paper also brings out the frame of this system and part of data structures which are used to retrieve data. How to work with these data structures is also presented.

Key words: NetFlow, flow data, distributed, muti-level directory

摘要：

对于网络流量工程而言，需要解决如何存储并高效地检索大量的网络流量数据。该文提出利用分布式多级目录技术实现NetFlow网络流数据信息存储与检索的一个完整方案，讨论NetFlow流数据的存储方式以及对其进行检索的优化方案，给出该系统的工作流程和框架、对流数据查询检索的部分数据结构及其工作方式。
