| 20090257456 | COORDINATED TIMING NETWORK HAVING SERVERS OF DIFFERENT CAPABILITIES - Communication and processing within a timing network that supports servers having different capabilities are facilitated. Individual servers of the network are dynamically updated without disrupting the operational characteristics of the timing network. New capabilities are not utilized between two servers until it is known that both servers are capable of supporting the new features. One server communicates to another server at an acceptable level of the another server. | 10-15-2009 |
| 20090259881 | FAILSAFE RECOVERY FACILITY IN A COORDINATED TIMING NETWORK - A failsafe recovery capability for a Coordinated Timing Network. The recovery capability facilitates recovery when communication is lost between two servers of the coordinated timing network. The capability includes checking another system's status in order to determine what action is to be taken. The status includes the stratum level of the servers and a version number indicating the code level of the servers. | 10-15-2009 |
| 20100100761 | MAINTAINING A PRIMARY TIME SERVER AS THE CURRENT TIME SERVER IN RESPONSE TO FAILURE OF TIME CODE RECEIVERS OF THE PRIMARY TIME SERVER - A primary time server of a Coordinated Timing Network remains as current time server, even if time code information of the primary time server is unavailable. The primary time server receives the necessary or desired timing information from a secondary time server and uses that information to maintain time synchronization within the Coordinated Timing Network. | 04-22-2010 |
| 20100100762 | BACKUP POWER SOURCE USED IN INDICATING THAT SERVER MAY LEAVE NETWORK - A server of a network of servers determines that its power source is failing. In response, the server communicates to one or more other servers of this network that it is leaving the network. This communication is powered by another power source. | 04-22-2010 |
| 20100223317 | SERVER TIME PROTOCOL MESSAGES AND METHODS - 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. | 09-02-2010 |
