Exchanging runtime state information between datacenters with a gateway using a controller bridge

One or more non-transitory computer-readable storage media storing one or more computer instructions which, when executed by one or more processors, cause the one or more processors to perform:

• receiving one or more first runtime state data from one or more logical sharding central control planes (“CCPs”) controlling one or more logical sharding hosts;
• receiving one or more second runtime state data from a gateway that is controlled by a CCP that also controls one or more physical sharding hosts, wherein the one or more second runtime state data received from the gateway comprises a mapping between virtual network identifiers (“VNIs”) and a gateway remote tunnel endpoint (“RTEP”);
• aggregating to aggregated runtime state data, the one or more first runtime state data received from the one or more logical sharding CCPs and the one or more second runtime state data received from the gateway;
• determining updated runtime state data based on the aggregated runtime state data, the one or more first runtime state data, and the one or more second runtime state data;
• and
• causing at least one of the one or more logical sharding CCPs and the gateway to manage or control logical switches or virtual switches based at least on the updated runtime state data.

A controller bridge implemented in a computer network and configured to implement mechanisms for dynamically exchanging runtime state data between datacenters, the control bridge comprising:

• one or more processors;
• one or more memory units;
• and
• one or more non-transitory computer-readable storage media storing one or more computer instructions which, when executed by the one or more processors, cause the one or more processors to perform:
• receiving, by the controller bridge, one or more first runtime state data from one or more logical sharding central control planes (“CCPs”) controlling one or more logical sharding hosts;
• receiving, by the controller bridge, one or more second runtime state data from a gateway that is controlled by a CCP that also controls one or more physical sharding hosts, wherein the one or more second runtime state data received from the gateway comprises a mapping between virtual network identifiers (“VNIs”) and a gateway remote tunnel endpoint (“RTEP”);
• aggregating, by the controller bridge, to aggregated runtime state data, the one or more first runtime state data received from the one or more logical sharding CCPs and the one or more second runtime state data received from the gateway;
• determining, by the controller bridge, updated runtime state data based on the aggregated runtime state data, the one or more first runtime state data, and the one or more second runtime state data;
• and
• causing at least one of the one or more logical sharding CCPs and the gateway to manage or control logical switches or virtual switches based at least on the updated runtime state data.
