Software-defined networking disaster recovery

摘要

Embodiments relate to software-defined networking (SDN) disaster recovery. An aspect is a system that includes an SDN controller configured to interface with a plurality of servers and switches in a network. The SDN controller includes processing circuitry configured to perform a method that includes establishing a plurality of flows, by the SDN controller, between a plurality of switches and pairs of servers in a network, including at least two different pairs of server types. Each server type runs a different operating system and a different disaster recovery manager in an active/active configuration. Data migration is controlled, by the SDN controller, between the pairs of servers in the network. The SDN controller dynamically reallocates the flows between the switches and the pairs of servers in the network based on detecting a fault in the network.

1. A system for software-defined networking (SDN) disaster recovery, the system comprising:
an SDN controller configured to interface with a plurality of servers and switches in a network, the SDN controller comprising processing circuitry configured to perform a method comprising:
establishing a plurality of flows, by the SDN controller, between the switches and pairs of the servers in the network, including at least two different pairs of server types, wherein each server type runs a different operating system and a different disaster recovery manager in an active/active configuration;controlling data migration, by the SDN controller, between the pairs of the servers in the network;dynamically reallocating the flows, by the SDN controller, between the switches and the pairs of the servers in the network based on detecting a fault in the network;identifying, by the SDN controller, a first pair of the servers comprising a first primary server and a first secondary server of a first server type, and a second pair of the servers comprising a second primary server and a second secondary server of a second server type, wherein the first and second primary servers are at a first geographic location and the first and second secondary servers are at a second geographic location;reallocating, by the SDN controller, data between the first and second primary servers; andreplicating the reallocating, by the SDN controller, between the first and second secondary servers.
