Abstract: A stratum-1 configuration for a timing network is defined. The stratum-1 configuration includes a single active stratum-1 server usable in ensuring that the servers in the network use the same primary reference time to synchronize their clocks. The servers in the network are synchronizing to the same root primary reference time and synchronization accuracyis not dependent on the quality of an external time source or of the existence of an external time source at the stratum-1 server.

Abstract: PROBLEM TO BE SOLVED: To provide a protocol for communication with a timing function used in a data processing network for providing synchronization, via an execution of a machine instruction of receiving a plurality of commands. SOLUTION: Such interaction is provided through the use of a command response block and a command response block related thereto. A timing parameters is determined by this manner, and corrected and communicated. As a result thereof, a plurality of servers or nodes in the data processing network is remarkably simplified about the existence as a regulation timing network (CTN), and the same large data file can be cooperatively operated.

Abstract: Server time protocol (STP) messages and methods of exchange thereof are provided for facilitating synchronization of processing units of a timing network. The STP messages include exchange time parameters (XTP) commands and responses, and STP control (STC) commands and responses. XTP message exchange processing includes: generating an XTP message command at a first processing unit including a command transmit timestamp field set by the first processing unit and a command receive timestamp field which is unset by the first processing unit; transmitting the XTP message command to a second processing unit; setting the command receive timestamp field in the XTP command with the time the XTP command is received at the second processing unit; and generating an XTP message response at the second processing unit, the message response including the command transmit timestamp set by the first processing unit and the command receive timestamp set by the second processing unit.

Abstract: Recoveryis provided in a timing network. A configuration is defined for that network, and in that configuration, an active primary server is identified that provides a clock source for the network. Additionally, an alternate server is identified that can perform the role of the active primary server, should the active primary server fail. In response to a failure of the primaryserver, the alternate server detects the failure and performs takeover of the primary server.

Abstract: In a networked data processing system, the updating of timing parameters is carried out via a process in which the detection of the loss of communications with the network is not immediately employed as an indication of parameter invalidity but rather the process employs a system specific delay which permits actions such as server or link recovery to occur without necessitating the declaration of timing parameter invalidity.
