Clock Synchronization Sample Clauses

Clock Synchronization. Production network devices must have internal clocks synchronized to reliable time sources.

Clock Synchronization. Supplier shall ensure that the clocks of all relevant information processing systems within the Supplier's environment have been synchronized with an agreed accurate time source to support tracing and reconstitution of activity timelines.

Clock Synchronization. An important question is how practical the synchrony assumption is, which will be the topic of this section. The synchrony assumption essentially states that all honest replicas’ messages arrive in time. This requires two properties: (i) a bounded message delay and (ii) locked step execution, i.e., honest replicas enter each round roughly at the same time. The second property is important because, if replica i enters a round much earlier than replica j, then i may end up finishing the round too soon without waiting for j’s message to arrive. In our protocol, for example, this could prevent i from detecting leader equivocation and result in a safety violation. The XFT paper provided some justification for the bounded message delay assumption in certain applications [26]. But we still need a mechanism to enforce locked step execution. To this end, we will use the following clock synchronization protocol, which may be interesting outside Byzantine agreement. It is a variation of the clock synchronization protocol by Xxxxx et al. [10]. The key change is to have parties sign independently in parallel (as opposed to sequentially) to facilitate the use of threshold signatures. The protocol will be executed at known time intervals. We call each interval a “day”.

Clock Synchronization. Clocks of all servers provisioned as a part of rendering the Service are synchronized to the primary time source provided by the cloud provider, which hosts the Environment/s used to provide the Service.

Clock Synchronization. The real time clocks in all building control panels and workstations shall be synchronized on command of an operator. The system shall also be able to automatically sequence all system clocks, daily from any operator designated device in the system. The system shall automatically adjust for daylight savings and standard time if applicable.

Clock Synchronization. There are several works that address the issue of clock synchronization in em- bedded devices. We assume that the clock synchronization takes place before the agreement protocol begins to execute and that there is a prescheduled clock cycle available to the nodes. One particular example of such clock synchronizing protocols is provided in [19]. Here the authors propose HARMONIA, a clock synchronization protocol that executes in very little time. A round is defines as the time between two consecutive transmission slots for a particular transmitter. Hence each round consists of multiple transmission slots for different transmitter-receiver/s sets. This definition of rounds provide these proper- ties: 1. If a message is sent in round k, it will reach the recipient before round k + 1. 2. If a node vi does not receive a message from another node vj in round k +1 =⇒ node vj did not send the message in round k. We will work with the assumption that all the nodes are connected such that the degree of every node is at least 2t + 1 where t is the number of faulty nodes in the system. Formally, if the set of nodes is N = {v1, v2, · · · , vn}, deg(vi) ≥ t + 1 , ∀vi ∈ N

Clock Synchronization. The clocks of all relevant information processing systems within an Xxxxxx+Gyr or security domain are synchronised to a single reference time source.

Clock Synchronization. Process of precisely coordinating or matching two or more activities, devices, or processes in time.
