Abstract
Systems and methods for horizontal synchronization are implemented by a first node with a second node adjacent to the first node in a network with a control plane. The horizontal synchronization manages and corrects for a state of a service which is resizable. The systems and methods include providing a first horizontal synchronization message to the second node with a first state comprising the state of the service at the node and a first size comprising a size of the service at the node; receiving a second horizontal synchronization message from the second node with a second state comprising the state of the service at the second node and a second size comprising a size of the service at the second node; detecting a mismatch of the service with the second node based on the second horizontal synchronization message; and performing a recovery action to correct the mismatch.
