Abstract: A technique for establishing a logical path between two servers in a coordinated timing network of processing environment is provided. The technique includes the exchange of command and response message pairs by a server and an attached server, via a physical link. The server transmits a command message to an attached server to establish a server-time-protocol(STP) logical path and receives a response from the attached server. The technique also includes the server receiving a request transmitted by the attached server to establish an STP logical path to the server and transmitting a response to the attached server s request. A logical path between the server and the attached server is established if the attached server s response indicates that the server s request was accepted bythe attached server and if the server s response indicates that the attached server s request was accepted by the server.

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: 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 bythe 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.
