Abstract:
1. A method for determining a time delay of a network having i) a transmitting node and ii) a receiving node, wherein each of the transmitting node and the receiving node comprises a Data Link Layer (DLL), a management layer, and a Physical Layer (PHY), the method comprising: in response to the DLL of the transmitting node receiving a first packet of information from a data source, determining a time that the first packet was received by a layer above a Medium Access Control (MAC) layer of the DLL of the transmitting node; forwarding the time that the first packet was received by the DLL of the transmitting node to the management layer of the transmitting node; forwarding information in the first packet to the PHY of the transmitting node; sending the information in the first packet to the receiving node using the PHY of the transmitting node; and determining, using circuitry, the time delay of the network by subtracting the time the time that the first packet was received by the DLL of the transmitting node from a transmit time provided via the management layer of the receiving node, the transmit time being a point in time that the information of the first packet is ready to be transmitted to a data sink by the receiving node.
