摘要
云计算中网络的监控任务是一件重要和复杂的工作.在云计算网络中的安全设备不仅要监控外网流量,还要监控内网流量.现有使用SDN和OpenFlow对网络流量监控的研究都基于每种设备仅存在一台的前提,受限于安全设备的数量,性能和效率受到限制.本文在OpenFlow上提出了一种云计算网络流量监控架构和算法,支持多台同类型的设备同时工作,可以在云计算网络中,实现灵活高效的网络流量监控.
Monitoring networks in cloud is important and complex. In the cloud computing, network security equipment does not only monitor external network traffic, but also review the traffic within the network to resist attacks. There are some researches that introduce SDN and Open Flow to route the traffic to security device. However, these methods are limited by the number of devices of the same type, and their performance is hence affected. In this paper, we propose a new flexible cloud computing monitoring framework based on Open Flow. And we also propose the corresponding algorithm to improve the performance and efficiency.By doing so,we can monitor the network traffic efficiently and flexibly.
