Abstract
A network captured traffic distribution device may receive captured data packets including original destination information. The captured data packets may then be encapsulated with, for example, new address information so that they may be transmitted toward a destination intended by the network capture traffic distribution device and not the original destination. Captured data packets may also be reformatted by the network capture traffic distribution device in order to, for example, be compatible with one or more devices communicatively coupled to the network capture traffic distribution device. Optionally, the encapsulated and/or reformatted captured data packets may further be encrypted prior to transmission toward their intended destination.
Claims31
A device comprising:
- a plurality of ingress ports configured to receive a traffic flow of captured data packets from a source of captured data packets and transmit the traffic flow of captured data packets to a switch;
- a plurality of egress ports configured to receive encapsulated captured data packets from the switch and transmit encapsulated captured data packets from the device toward an external device via a communication network;
- the switch communicatively coupled to the plurality of ingress ports, the plurality of egress ports, and at least one of a logic component and a processor and configured to transfer captured data packets received from the plurality of ingress ports to the at least one logic component and processor and transfer data and encapsulated captured data packets from the at least one logic component and processor to the plurality of egress ports;
- the at least one logic component and processor, communicatively coupled to the switch and configured to receive captured data packets from the switch, execute instructions stored in a memory, wherein execution of the instructions includes encapsulating the received captured data packets for transmission to the external device via the communication network, and transmit encapsulated captured data packets to the switch;
- and
- a memory, communicatively coupled to the at least one logic component and processor and configured to store instructions executable by the at least one logic component and processor.

A method comprising:
- receiving, at a network captured traffic distribution device, a traffic flow of captured data packets, wherein the captured data packets are received via at least one of a mirror port resident on a source of the captured data packets and a traffic capture point located along a communication link between two communicating devices;
- encapsulating, by the network captured traffic distribution device, the received captured data packets for transmission to an external device via a communication network;
- and
- transmitting, by the network captured traffic distribution device, the encapsulated captured data packet to toward the external device via the communication network.

A method comprising:
- receiving, at a network captured traffic distribution device, a traffic flow of captured data packets, wherein the captured data packets are received via at least one of a mirror port resident on a source of the captured data packets and a traffic capture point located along a communication link between two communicating devices;
- reformatting, by the network captured traffic distribution device, a captured data packet included in the traffic flow of captured data packets into a format compatible with a data storage device communicatively coupled to the network captured traffic distribution device;
- and
- transmitting, by the network captured traffic distribution device, the reformatted captured data packet to toward the data storage device.
1 more element
A system comprising:
- a source of a traffic flow of captured data packets communicatively coupled to a network captured traffic distribution device, wherein the source performs at least one of capturing data packets transmitted between two nodes and receiving captured data packets via a minor port of a network switch and transmits captured data packets included in the traffic flow to the network captured traffic distribution device;
- the network captured traffic distribution device, wherein the network captured traffic distribution device is configured to receive the captured data packets from the source, encapsulate the received captured data packets for transmission to an external device via a communication network, and transmit the encapsulated captured data packet to toward the external device via the communication network;
- and
- the external device communicatively coupled to the network captured traffic distribution device via the network and configured to receive the encapsulated captured data packet from the network captured traffic distribution device and store the received encapsulated captured data packet.
