Synchronizing peer nodes of a multi-chassis switching cluster

Abstract:

Implementations generally relate to synchronizing peer nodes in networks. In one embodiment, a method includes generating a data sequence number. The method also includes associating the data sequence number with a data item. The method also includes sending the data item and the data sequence number to each peer node of a plurality of peer nodes. The method also includes determining if an acknowledgment has been received from each peer node, wherein each acknowledgment indicates the peer node that sent the acknowledgment and indicates the data sequence number. The method also includes resending the data item and the data sequence number to one or more peer nodes based on a predetermined policy.
