SERVER TIME PROTOCOL CONTROL MESSAGES AND METHODS
First Claim
1. A method of executing a server time protocol (STP) control message command, the method comprising:
- receiving an STP control message command at a second server sent from a first server, the STP control message command being defined for computer execution according to a computer architecture, the STP control message command comprising;
an operation code field containing a value that specifies an operation to be performed, the operation to be performed comprising one of an update request operation, one or more read operations, or one or more notification operations, wherein the update request operation comprises a request-stratum-1 configuration change operation, the read operations comprise read attach server state and read CTN parameters, and the notification operations comprise establish an STP path, remove an STP path, set arbiter takeover mode, reset arbiter takeover mode, and arbiter takeover state active;
responsive to receiving the STP control message command, performing an operation at the second server defined by the operation code of the STP control message command and providing a result based thereon, the result being operation dependent; and
sending an STP message response from the second server to the first server, the STP message response comprising the result of performing the operation specified in the STP control message command.

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.

16. A system for executing a server time protocol (STP) control message command, the system comprising:
a second server for receiving an STP control message command sent from a first server, the STP control message command being defined for computer execution according to a computer architecture, the STP control message command comprising; an operation code field containing a value that specifies an operation to be performed, the operation to be performed comprising one of an update request operation, one or more read operations, or one or more notification operations, wherein the update request operation comprises a request-stratum-1 configuration change operation, the read operations comprise read attach server state and read CTN parameters, and the notification operations comprise establish an STP path, remove an STP path, set arbiter-takeover mode, reset arbiter-takeover mode, and arbiter-takeover state active; responsive to receipt of the STP control message command, the second server performing an operation defined by the operation code of the STP control message command and providing a result based thereon, the result being operation dependent; and the second server sending an STP message response to the first server, the STP message response comprising the result of performing the operation specified in the STP control message command. - View Dependent Claims (17, 18, 19, 20)
