Methods and systems for determining time delays of networks are disclosed. For example, 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) is disclosed. The method includes determining a time that the first packet was received by the transmitting node, forwarding the time that the first packet was received to the management layer of the transmitting node; forwarding information in the first packet to the transmitting node; and determining 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.
