Abstract: Some embodiments provide a method of identifying packet latency in a software defined datacenter (SDDC) that includes a network and multiple host computers executing multiple machines. At a first host computer, the method identifies and stores (i) multiple time values associated with several packet processing operations performed on a particular packet sent by a first machine executing on the first host computer, and (ii) a time value associated with packet transmission through the SDDC network from the first host computer to a second host computer that is a destination of the particular packet. The method provides the stored time values to a set of one or more controllers to process to identify multiple latencies experienced by multiple packets processed in the SDDC.

Abstract: In an embodiment, a computer-implemented method for dynamically exchanging runtime state data between datacenters using a controller bridge is disclosed. In an embodiment, the method comprises: requesting, and 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; requesting, and receiving, one or more second runtime state data from one or more physical sharding CCPs controlling one or more physical sharding hosts; aggregating, to aggregated runtime state data, the one or more first runtime state data and the one or more second runtime state data; 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 transmitting the updated runtime state data to the logical sharding CCPs and physical sharding CCPs.
