提供了一种对报文进行流量监管的方法及系统。引入了测量引擎,用以辅助包处理器完成报文的测量和标记工作,测量和标记后,包处理器还可以对报文进行解析和修改。一方面,减少了包处理器实现报文测量和标记的开销;另一方面,能够实现流量管理器中所不能实现的重新标记的监管动作。 A method and system for monitoring traffic of a packet are provided. The introduction of a measurement engine to assist the packet processor to measure and mark the message, measure and mark, the packet processor can parse and modify the message. On the one hand, the packet processor reduces the overhead of message measurement and marking; on the other hand, the re-marking of regulatory actions that can not be implemented by the traffic manager can be implemented.
