Abstract
In one embodiment, a device (e.g., a sync daemon) connects to peer nodes in a communication network. Each of the peer nodes has a switch that supports a flow table and an action table. The device facilitates a connection between a switch of a first peer node and a switch of a second peer node, and maintains the flow table and the action table of each of the peer nodes, such that the flow tables and the action tables are kept in synchronization with one another across each of the peer nodes via a distributed hash table.
