Patent ID: 8856367

Claim:
An arrangement including a gateway, a time generator in a first network, and a time receiver in a second network arranged in a closed loop system, the gateway for interchanging time markers between the time generator and the time receiver, wherein the first network includes a first protocol and the second network includes a different second protocol for the time markers; wherein the time markers each comprise data packets having a payload comprising a coded time information item; wherein the gateway receives a first time marker over the first network, directly extracts the coded time information item from the first time marker, inserts the coded time information item into a new data packet of the second protocol producing the new data set, and transmits the new data packet as a second time marker over the second network and over an entire path of the closed-loop system comprising the gateway, the time generator in the first network, and the time receiver in the second network; wherein the time markers are interchanged over the second and a third network having a time receiver by repeatedly receiving, extracting, producing, and transmitting by a further device between the second network and the third network; wherein an accumulated propagation time delay in repeatedly converted time markers is taken into account in the time receiver of the third network; and wherein generation of the second data packet takes into account a conversion delay by adding the time required for the conversion of the coded time information from the first data packet to the second data packet to a value in a data field for propagation time delays in the second time marker.
