基于IPv6的分布式实时网络测量系统设计

Design of system for distributed real-time measurement based on IPv6

针对当前许多网络测量系统无法进行实时网络流量监测以及无法支持下一代互联网协议IPv6等不足,提出了一种基于IPv6的比特模式流定义方法和数据结构实时网络测量系统.系统通过在IPv6扩展首部中承载测量信息实现精确流测量,减少了测量开销,提高了测量效率.比特模式流定义方法提供了一种灵活的按需流定义方式,使系统能在IPv4/IPv6环境下实现流测量工作.实验证明,整个系统运行正常、效果良好.

In consideration of the drawbacks of current measurement systems, such as difficult in monitoring real-time network flow and not supporting the next generation Internet protocol（IPv6）. A real-time network measurement system was proposed on the basis of bit-pattern based flow definition method and data structure. The system implemented the accurate flow measurement by carrying the measurement information in IPv6 extension header, decreasing the overhead and improving the performance. The bit-pattern-based flow definition method provided the flexible flow definition and made the system realize measuring flow in IPv4 and/or IPv6. The simulations showed that the whole system can run well.
