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.
A method of migrating a virtual sub-network (VSN) of source virtual entities for processing traffic packets from a source network of servers to a destination network of servers, by an orchestrator, the method comprising:
A system for supporting and migrating a virtual sub-network (VSN) of source virtual entities for processing traffic packets, from a source network of servers to a destination network of servers, the system comprising:
An orchestrator for supporting and migrating a virtual sub-network (VSN) of source virtual entities for processing traffic packets, from a source network of servers to a destination network of servers, the orchestrator comprising a network interface for transmitting and receiving data, a machine readable memory for storing instructions, and at least one processor for executing instructions stored in the memory that when executed, configure the orchestrator to:
