Abstract

An internet activity analyzer includes a network interface controller, a packet capturing module, a packet analysis module, and a data management module. The network interface controller is connected to a transmission medium for a network segment and is arranged to receive the stream of data packets passing along the medium. The packet stream is filtered to remove undesired packet data and is stored in a raw packet data buffer. The packet data is decoded at the internet protocol layer to provide information such as timing and sequencing data regarding the exchange of packets between nodes and the packet data for exchanges between multiple nodes may be recompiled into concatenated raw transaction data which may be coherently stored in a raw transaction data buffer. An application level protocol translator translates the raw transaction data and stores the data in a translated transaction data buffer. The translated data provides high level information regarding the transactions between nodes which is used to monitor or compile statistics regarding network or internetwork activity. The data management module communicates with the packet capturing module and the packet analyzer and, particularly, the data in the raw packet, decoded packet, raw transaction, and translated transaction data buffers to provide real time and stored analytical information concerning internet activity.
