Abstract

An integrated switch tap device for managing and monitoring network traffic is provided. The device includes a set of network ports for receiving and outputting the network traffic. The device also includes a first logic arrangement for performing routing functionalities and a first CPU for processing the routing functionalities. The device further includes a set of monitoring ports that is coupled to one or more monitoring devices. The device yet also includes a first tap module, which is configured at least for intercepting at least part of the network traffic flowing through the network device, creating a copy of at least part of the network traffic, and forwarding the copy to at least one of the set of monitoring ports. The device moreover includes a second CPU configured at least for processing tap functionalities associated with the first tap module.

Claims

1. An integrated switch tap device for managing and monitoring network traffic, comprising:

a set of network ports, said set of network ports being configured for at least one of receiving said network traffic and outputting said network traffic from said integrated switch tap device, said set of network ports including at least a first network port;

a first logic arrangement configured at least for performing routing functionalities, wherein said routing functionalities including analyzing said network traffic, determining a destination for at least a portion of said network traffic, and directing said network traffic from said first network port to a second network port of said set of network ports;

a first central processing unit (CPU) configured at least for processing said routing functionalities;

a set of monitoring ports, said set of monitoring ports being coupled to one or more monitoring devices;

a first tap module, said first tap module being configured at least for intercepting at least part of said network traffic flowing through said integrated switch tap device, creating a copy of said at least part of said network traffic, and forwarding said copy of said at least part of said network traffic to at least one of said set of monitoring ports;

said first tap module including a filtering functionality, wherein said filtering functionality includes identifying types of data packets from said network traffic for forwarding to said at least one of said monitoring ports, wherein said filtering functionality is user-configurable; and

a second CPU separate from the first CPU configured at least for processing tap functionalities associated with said first tap module, whereas said network traffic is configured to traverse said integrated switch tap device whether power is provided to circuitry of said integrated switch tap device.

2. The integrated switch tap device of claim 1 further including a mirroring functionality, wherein said mirroring functionality includes said creating of said copy of said at least part of said network traffic.

3. The integrated switch tap device of claim 2 wherein said first tap module is configured for performing said mirroring functionality.

4. The integrated switch tap device of claim 3 wherein said first logic arrangement is configured for performing said mirroring functionality.

5. The integrated switch tap device of claim 1 wherein each network port of said set of network ports is bidirectional and include at least an input network port for receiving inbound network traffic and an output network port for forwarding outbound network traffic.

6. The integrated switch tap device of claim 1 wherein said first tap module includes an aggregator functionality, wherein said aggregator functionality includes aggregating data packets received from said set of network ports.

7. The integrated switch tap device of claim 6 further including a buffering component, wherein said buffering component is positioned between said first tap module and said set of monitoring ports, wherein said buffering component is configured at least for managing network traffic to said set of monitoring ports.

8. The integrated switch tap device of claim 7 further including a second tap module, wherein said second tap module being configured at least for intercepting at least part of said network traffic flowing through said integrated switch tap device, creating a copy of said at least part of said network traffic, and forwarding said copy of said at least part of said network traffic to at least one of said set of monitoring ports, wherein said second tap module is not said first tap module.

9. The integrated switch tap device of claim 8 further including a second logic arrangement for analyzing said network traffic and for displaying statistical data pertaining to said network traffic.

10. The integrated switch tap device of claim 9 further including a visual display arrangement is one of a non-opaque viewing arrangement and an LCD (liquid crystal display) screen.

11. The integrated switch tap device of claim 10 wherein said statistical data displayed on said visual display arrangement is configured to be cycled through.

12. The integrated switch tap device of claim 9 further including a port indicator, wherein said port indicator is configured to display status of a network port of said set of network ports.

13. An integrated switch tap device for managing and monitoring network traffic, comprising:

a set of network ports, said set of network ports including a set of input network ports for receiving said network traffic and a set of output network ports for forwarding said network traffic, said set of network ports including at least a first network port with a first input network port and a first output network port;

a set of uplink ports, wherein said set of uplink ports is configured for receiving said at least part of said network traffic from said set of network ports;

a logic arrangement configured at least for performing routing functionalities, wherein said routing functionalities including analyzing said network traffic, determining a destination for at least a portion of said network traffic, and directing said network traffic from one of said set of network port to one of said set of uplink ports;
