Abstract:
1. A method of transferring a telecom-based master clock from a first network node to a second network node across an unsynchronized point-to-point network connection that utilizes variable-length packets comprising: deriving, from an external source, said telecom-based master clock at said first network node; generating a data transmission clock, at said first network node, that is substantially synchronized with said telecom-based master clock, said data transmission clock being a higher frequency clock than said telecom-based master clock; and transmitting data in variable-length packets from said first network node to said second network node across said unsynchronized point-to-point network connection, said data being transmitted at a transmission rate defined by said data transmission clock to carry timing information from said telecom-based master clock to said second network node.
