| Zusammenfassung: | Techniques for tracking dynamically negotiated port connections in a network include collecting statistical information on packets that are sent between nodes on a network, inspecting packets of control connections to detect payload fragments that denote ephemeral port negotiation and producing a mapping from a ephemeral connection flow_id to a control connection flow_id. The techniques also include checking the flow_id to see whether a flow record maps to a control connection. |
