摘要： During each node's awake period, each node multicasts the relative time or slot of their next awake period (beaconing interval) to all neighboring nodes. This enables each node to intelligently and independently schedule the time slot of its next transmission based on the beaconing intervals of the nodes it has heard from. During each active (awake) interval, a node builds statistics of the future transmission/receive times of its neighbors and uses them to determine its next transmission time. In one proposed implementation, at the end of an active interval, a node picks the time slot with the highest counter for its next transmission. In another proposed implementation, at the end of an active interval, a node picks one of the slots with a weighted probability; the weight of each slot is proportional with the value of the counter associated with the slot

摘要： A synchronization request message is transmitted from a requesting node to a neighboring node. Upon transmission at the synchronization request message the requesting node stores a unique message identification associated with the request message and as a first timestamp associated with the transmission time of the synchronization request message by the requesting node. The neighboring node receives the synchronization request message and stores a second timestamp associated with the time that the synchronization request message was received by the neighboring node. Thereafter, the neighboring node transmits to the requesting node a synchronization response message that includes the message identification and the second timestamp. The requesting node calculates a timer offset value based on the first and second timestamps. The timer offset values may then be shared with other nodes in the network so that a summed offset may be used to transmit network messages across a plurality of nodes.

摘要： A method and system for synchronizing clocks on networked computers (206) is provided. This invention works with modem high-speed workstations and networks to improve clock synchronization between the computers. This invention employs techniques, which accurately predict the phase and frequency noise for each synchronization source and network path. Techniques are included which reduce the impact of delay spikes and oscillator wander while speeding up initial convergence. Also included are improved clock discipline processes, which can operate in frequency-lock, phase-lock and hybrid modes. This invention is specifically adapted to synchronize the clocks of host computers, routers, servers and workstations on LANs, WANs and the Intranet, WAN or LAN.

摘要： In a network based on IEEE 1588, comprising a plurality of nodes (201, 501) and a plurality of connections where each connection connects at least two nodes to allow communication between nodes including the exchange of messages according to a network protocol, the the synchronization of IEEE 1588 is improved by allowing multiple grandmaster clocks (701) to operate simultaneously in the system. Thus, the re-election protocol of IEEE 1588 is made obsolete. For this, a multitude of nodes form a subsystem implementing a high-availability grand master clock (301) according to the IEEE 1588 Standard, wherein the subsystem is configured to tolerate the failure of at least one of said nodes forming said subsystem. Bi-directional communication link (401) are configured for physically connecting a IEEE 1588 Master clocks (201) and/or IEEE 1588 Slave clocks (201) to the subsystem implementing a high-availability grand master clock (301).

摘要： A synchronous optical digital transmission system comprises a local interface unit (2) having a phase locked loop circuit (31, 34, 44) that senses and adjusts the phase of the clock signals (26) arriving from the remote unit to match the phase of the principal or local clock (30) so that the arriving data bit streams (24, 28) can be directly applied to the local system for further processing. The system is also designed to transmit and receive high speed and low speed data over a single fiber (46) operating in a diplex mode without adverse crosstalk effects by employing non-standard line coding techniques.
