Versioning system for network states in a software-defined network

A non-transitory, computer-readable medium having processor-executable instructions stored thereon for versioning network state of a network, the processor-executable instructions, when executed by a processor, facilitating the following:

• receiving, from a plurality of data plane devices, information regarding flow modifications made by respective data plane devices;
• tracking each flow modification made by the respective data plane devices, wherein the tracking includes storing a plurality of network states, wherein the plurality of network states include a current authoritative network state and a plurality of previous network states each corresponding to a previous network state before a previous flow modification;
• and
• sending the current authoritative network state to the plurality of data plane devices.

A method for versioning network state of a network, the method comprising:

• receiving, by a server executing a versioning controller, from a plurality of data plane devices, information regarding flow modifications made by respective data plane devices;
• tracking, by the server executing the versioning controller, each flow modification made by the respective data plane devices, wherein the tracking includes storing a plurality of network states, wherein the plurality of network states include a current authoritative network state and a plurality of previous network states each corresponding to a previous network state before a previous flow modification;
• and
• sending, by the server executing the versioning controller, the current authoritative network state to the plurality of data plane devices.
