Determining Characteristics of a Connection Traversing a Packet Switching Device

摘要

In one embodiment, characteristics of a connection traversing a packet switching device is determined, which includes, but not limited to, determining a network port number and/or address of an established connection based on a signature of the connection. In one embodiment, a packet switching device receives and forwards packets of particular communication between a device and a remote node in a network. The packet switching device maintains information of the particular communication and identification data for use in subsequent identification of said particular communication. In response to receiving a communications information request specifying a signature related to said particular communications, the packet switching device prepares and sends a response, which typically includes matching the signature to said maintained identification data resulting in identification of said information including a characterization of said particular communications, and sending a reply including the characterization of said particular communications.

主权项

1. A method, comprising:
initiating, by a device, particular communications with a remote node, with said particular communications traversing a packet switching device in a network; subsequent to said initiating said particular communications with the remote node, sending a communications information request from the device specifying a signature related to said communications; and receiving information, by the device, including a characterization of said particular communications responsive to the communications information request.
