System and method for sending packets using another device's network address

摘要

A network analyzer gets configuration information, usually in the form of a configuration packet sent from a network monitor. The configuration information comprises a second device network address and a third device network address. The second device network address is that of the network monitor and the third device network address is that of a communication device that is to be monitored.;When the network analyzer sees packets from the monitored communication device, it can send the results to the network monitor for analysis without having to be configured with a unique network address. The network analyzer sends an original packet using the network address of the communication device as the source address and using the network address of the network monitor as the destination address.

1. A system comprising:
a first device configured to receive a first configuration packet that contains configuration information from a network monitor, get the configuration information comprising a configured network address of a second device and a configured network address of a third device, wherein the first device does not have a network address, generate an original packet comprising a source network address that is the network address of the third device and a destination network address that is the network address of the second device, send the original packet, receive a packet, determine if the received packet is a second configuration packet, the sent original packet, or a packet that has the source network address or the destination network address of the third device, in response to the received packet being the second configuration packet, get a second configuration information from the second configuration packet, in response to the received packet being the sent original packet, ignoring the received packet, and in response to the received packet being the packet that has the source address network address or the destination network address of the third device, send a packet that comprises the source network address and the destination network address.
