Abstract: The disclosure provides an approach for decentralizing control plane operations in a network environment that includes transport nodes configured to implement a logical overlay network. A method includes transmitting a global list of transport nodes to each of the plurality of transport nodes from a management plane, the global list including an ordered list of the plurality of transport nodes. The method also includes transmitting a neighbor index value to each of the plurality of transport nodes, where the transport nodes each compute a corresponding list of neighbor transport nodes based on the neighbor index value and the global list of transport nodes. The method also includes, based on determining an update to a state of the logical overlay network has occurred by a first transport node, transmitting an update message from the first transport node to each transport node in the first transport node's list of neighbor transport nodes.

Abstract: The disclosure provides an approach for in-place conversion of a virtual switch on a host. Techniques are provided for in-place conversion of a virtual switch from a first type of virtual switch to a destination type of virtual switch. A method includes rekeying, by a second manager agent, one or more uplink ports associated with one or more logical switches implemented by the virtual on the host with the unique identifier. The rekeying includes updating one or more existing uplink port identifiers assigned to the one or more uplink ports with the unique identifier associated with a first manager agent. The method includes removing, by the first manager agent, an association of the one or more uplink ports with the opaque network; and informing the first manager and the second manager that the virtual switch is of the destination type of virtual switch.
