Abstract

An arrangement for processing data traffic flowing through a network is provided. The arrangement includes a data interface for receiving the data traffic. The arrangement also includes an inspection engine for analyzing the data traffic, wherein the analyzing is performed on at least payload data. The arrangement further includes means for routing the data traffic through the network, wherein the means for routing is configured to define one or more ports for transmitting the data traffic. The means for routing the data traffic is dynamic to balance the data traffic across multiple outgoing ports.

Claims

1. An arrangement for processing data traffic flowing through a network, comprising:

a data interface for receiving said data traffic;

an inspection engine for analyzing said data traffic, wherein said analyzing is performed on at least payload data; and

means for routing said data traffic through said network, wherein said means for routing is configured to define one or more ports for transmitting said data traffic, said means for routing said data traffic being dynamic to balance said data traffic across multiple outgoing ports.

2. The arrangement of claim 1 further including a media access control component for converting said data traffic from an analog signal to a digital signal.

3. The arrangement of claim 1 wherein said inspection engine is a deep-packet inspection engine.

4. The arrangement of claim 3 wherein said inspection engine is configured for filtering said data traffic based on a set of filtering criteria.

5. The arrangement of claim 4 wherein said set of filtering criteria is user-configurable.

6. The arrangement of claim 5 wherein said means for routing said data traffic include a load balancing engine.

7. The arrangement of claim 6 wherein said load balancing engine is configured for distributing said data traffic based on a set of parameters.

8. The arrangement of claim 7 wherein said set of parameters include percentage distribution for routing said data traffic through said multiple outgoing ports.

9. The arrangement of claim 8 further including a configuration module, wherein said configuration module is configured to provide an interface for receiving at least one of said set of parameters and said set of filtering criteria.

10. The arrangement of claim 1 further includes a statistic collector, wherein said statistic collector is configured to gather details about said data traffic.

11. A method for managing data traffic flowing through a network, comprising:

receiving a plurality of data packets;

analyzing payload data of said plurality of data packets based on a set of criteria; and

routing said plurality of data packets through said network, said routing includes defining one or more ports for transmitting said data traffic, wherein said routing is dynamically performed to balance said data traffic across multiple outgoing ports.

12. The method of claim 11 further including converting said plurality of data packets from an analog signal to a digital signal.

13. The method of claim 11 further including dropping a set of data packets of said plurality of data packets if said set of data packets fails to pass said set of criteria.

14. The method of claim 11 wherein said routing of said plurality of data packets is based on percentage distribution.

15. The method of claim 11 further including collecting statistical data about said data traffic, wherein said statistical data is available for further analysis.

16. The method of claim 11 wherein said set of criteria is user-configurable.
