1. A system for communicating network performance information of a node segment of a packet network, said system comprising:

  • an input/output (I/O) unit configured to communicate with at least one network communications device over a packet network; and

    a processing unit in communication with said I/O unit and configured to generate network performance information indicative of transmission characteristics of a node segment on the packet network, said processing unit further configured to alter an existing data packet by including the network performance information and a node segment identifier identifying the node segment in a payload of the existing data packet, the payload of the existing data packet containing existing non-network performance information data, and communicate the existing data packet containing the altered payload that includes the network performance information, the node segment identifier identifying the node segment, and the existing non-network performance information data using in-band signaling to a network communications device.
