摘要：A network analyzer includes a hardware-based accounting engine thatgenerates accurate statistics for traffic within a computer network. As the networkanalyzer receives packets, the accounting engine associates the network packets withrespective routing prefixes, and updates flow statistics for the routing prefixes. In this
manner, the accounting engine maintains accurate flow statistics for all packets receivedby network analyzer. The network analyzer includes a control unit that generates prefixdata to control the granularity of the traffic analysis. The control unit analyzes the flowstatistics maintained by the accounting engine, and adaptively updates the set of prefixesto control the granularity of the statistics. The control unit may generate the prefix dataas a forwarding tree having resolution nodes. Each node may associate a network prefixwith forwarding next hop data, as well as respective analysis control data to enable ordisable flow analysis for the prefix.
