Distributed clock network with time synchronization and activity tracing between nodes

摘要

Systems and methods are described for coordinating clocks in a distributed computing environment. In one embodiment, a plurality of groups of nodes are formed. Nodes within a group may be time-synchronized and time differences between groups may be tracked. Clock adjustments between groups may be accumulated for tracked activities. The accumulated clock adjustments may be used to determine an ordering of the tracked activities.

主权项

1. A method for tracking time, the method comprising:
sending, by a first node, a message indicative of an availability to be associated with a distributed clock group; in response to receiving an indication to associate with a first distributed clock group, joining the first distributed clock group; participating in a process to select a group leader for the first distributed clock group; communicating with the group leader to synchronize a clock on the first node with one or more clocks of other nodes of the first distributed clock group; establishing a boundary relationship with a second node of a second distributed clock group; receiving information indicative of a synchronized clock of the second distributed clock group; and determining a clock skew based at least in part on the information indicative of the synchronized clock of the second distributed clock group.
