Abstract: In cloud computing, for various reasons such as load-balancing, hotspot elimination, server consolidation, energy and cost savings, and system maintenance, there is a need to migrate a virtual sub-network of virtual entities from a source network of servers to a destination set of servers. Existing migration methods are limited to the migration of VM memory and controller states, where network entities are migrated individually. Embodiments of this disclosure include systems and methods for the stateful live migration of a multi-layer network, while maintaining live state convergence and consistency, and preventing network connection losses, packet disordering and packet drops.
