There is provided a high-speed IP flow mediation apparatus using a network processor. The apparatus includes a server collecting flow information regarding IP traffic on a high-speed line and a network processor board analyzing the collected information according to Internet applications using a network processor, and transferring the analyzed flow information to a plurality of flow analysis systems.

High-speed IP flow mediation apparatus using network processor

There is provided a method and apparatus for controlling traffic according to user that includes a statistics processing unit measuring traffic volume used according to user, calculating a traffic variation &#x394;V by using the measured traffic volume, and updating a traffic user list by comparing the calculated traffic variation &#x394;V; a traffic detecting unit determining whether abnormal traffic is generated in a network and transferring a control command according to priority in the traffic user list; and a packet controlling unit controlling a user's traffic according to the control command received from the traffic detecting unit.

Method and apparatus for controlling traffic according to user

A method of generating IP traffic flow based on a time bucket divides, in order to generate flows using all IP packets arriving in a preset time bucket, a previous time bucket flow table (PTBFT) and a current time bucket flow table (CTBFT) with reference to a current time when the flows are generated using IP packets collected from a high-speed line in a flow generating unit. Accordingly, the method allows real-time analysis of flows.

Method of generating IP traffic flow based on a time bucket

An apparatus and method for merging Internet traffic mirrored from multiple links are provided. A merged flow can be generated on the Internet having a characteristic of asymmetrical route through a technology of merging the traffic according to an identical characteristic based on correlation analysis using internet traffic mirrored from several spots of multiple links connected to a network to facilitate general analysis and specific application analysis of traffic.
