A METHOD OF, AND APPARATUS FOR, MONITORING TRAFFIC IN A COMMUNICATIONS NETWORK

摘要

For monitoring traffic in a communications network, network protocol requests sent over the network are obtained. The resulting network protocol responses sent over said network are also obtained. It is then determined which request corresponds to which response and each request and corresponding response pair is stored as a single request-response record. Preferably, the time of capture of the request in each record is stored. Moreover, a request lookup key may be created from specific attributes of the request. The requests and responses preferably adhere to the domain name system (DNS) protocol.
