Abstract: Aspects of methods and systems for determination and exchange of network timing information are provided. In one such method, a propagation delay of a network physical link is determined using a plurality of time stamps. The time stamps are provided by one or more sending nodes traversed by a packet along the network physical link. The length of the network physical link is calculated, utilizing the determined propagation delay. The determined propagation delay and/or the length of the network physical link is appended to the packet.
