Example methods and systems for priority-based network bandwidth allocation are described. In one example, a first computer system may detect an event indicating that network bandwidth allocation is required for a virtualized computing instance. The first computer system may identify, from multiple priority levels, a first priority level that is associated with (a) the virtualized computing instance, (b) a logical network element to which the virtualized computing instance is attached, or (c) a group that includes the virtualized computing instance or the logical network element. The first computer system may obtain network bandwidth capacity information associated with physical network adapter(s) capable of forwarding traffic associated with the virtualized computing instance. Based on the first priority level and the network bandwidth capacity information, the first computer system may configure a priority-based network bandwidth allocation policy that includes parameter(s) applicable to the traffic associated with the virtualized computing instance.

Priority-based network bandwidth allocation

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.

Decentralized control plane

Example methods and computer systems are provided for logical overlay network monitoring. The method may comprise: obtaining egress metric information associated with egress encapsulated packets that are sent by a source virtual tunnel endpoint (VTEP) to a destination VTEP over a logical overlay network; and obtaining ingress metric information associated with ingress encapsulated packets that are received by the destination VTEP from the source VTEP over the logical overlay network. The method may also comprise: performing a comparison to identify a divergence between the egress metric information and the ingress metric information; and based on the divergence, detecting a performance issue affecting logical overlay network connectivity between the source VTEP and the destination VTEP.
