1. A controller computer for managing a plurality of managed forwarding elements that implement different logical networks, the controller computer comprising:

  • an interface that receives input logical forwarding plane data in terms of input events, said input logical forwarding plane data comprising updates to logical forwarding planes of logical networks, wherein each logical network comprises a set of logical forwarding elements that is implemented by a set of managed forwarding elements;

    a converter that converts the input logical forwarding plane data for each logical network to output physical control plane data for the logical network by processing the input events, said physical control plane data for subsequent translation into customized physical control plane data for each managed forwarding element; and

    an input scheduler that (i) categorizes the input events into different groups related to different logical networks, and (ii) defines a schedule for supplying each group of the input events for each logical network to the converter in a manner such that each group of input events related to each logical network is processed together by the converter.
