Abstract: Synchronization of traffic multiplexing in link aggregation is described. In an embodiment, a first link aggregator and a second link aggregator are associated with a plurality of links. The first link aggregator maintains an identifier for each link indicating at least a state of enabled or disabled. A synchronized clock is established between the first link aggregator and the second link aggregator. A particular link of the plurality of links is transitioned. Wherein, the transitioning is performed by the first link aggregator sending, to the second link aggregator, a first message identifying a particular time to transition the particular link. The first link aggregator receives, from the second link aggregator, a second message indicating that the particular time is acceptable. In response to a determination that the second message indicates that the particular time is acceptable and that the synchronized clock has reached the particular time, transitioning the link.
