Abstract: A method for network address management is provided. Embodiments include determining a creation of a namespace associated with a cluster of computing devices, wherein a subset of computing resources of the cluster of computing devices is allocated to the namespace. Embodiments include assigning, to the namespace, a network address pool comprising a plurality of network addresses in a subnet, wherein the assigning causes the plurality of network addresses to be reserved exclusively for the namespace. Embodiments include receiving an indication that a pod is added to the namespace. Embodiments include, in response to the receiving of the indication, assigning a network address from the network address pool to the pod.

Abstract: An administrator agent and local worker agents are provided in nodes of a distributed system to support dynamic tracing of runtime data. Trace profiles are associated with the nodes on which the local worker agents reside. The local worker agents monitor the runtime data for an error, and the administrator agent adjusts the trace profile(s) in response to the error(s). The administrator agent sends the adjusted trace profile(s) to the local worker agents, so as to enable trace output data of traces performed by the nodes to be increased or decreased.

Abstract: The disclosure provides an approach for providing an extendable system health management framework in a network. Embodiments include receiving, by a manager, a system health plugin. Embodiments include determining, by the manager, an association between the system health plugin and a host in the network based on the host satisfying one or more conditions. Embodiments include providing, by the manager, the system health plugin to the host for installation in a system health agent on the host. Embodiments include receiving, by the manager, from the host, status information for the system health plugin.

Abstract: Example methods and systems are provided for simulation-based cross-cloud connectivity checks. One example method may include injecting a connectivity check packet in a first cloud environment, and obtaining first report information associated with a first stage of forwarding the connectivity check packet from one or more first observation points in the first cloud environment. The method may also comprise: based on configuration information associated with one or more second observation points in the second cloud environment, simulating a second stage of forwarding the connectivity check packet towards a second virtualized computing instance via the one or more second observation points. The method may further comprise: generating second report information associated with the simulated second stage to identify a connectivity status between a first virtualized computing instance and the second virtualized computing instance based on the first report information and the second report information.

Abstract: Example methods and systems for intent-based network virtualization design are disclosed. One example may comprise: obtaining configuration information and traffic information associated with multiple virtualized computing instances, processing the configuration information and traffic information to identify network connectivity intents and mapping the network connectivity intents to a logical network topology template. Based on a first switching intent, a first group may be assigned to a first logical network domain and the logical network topology template configured to include a first logical switching element. Based on a second switching intent, a second group may be assigned to a second logical network domain and the logical network topology template configured to include a second logical switching element. Based on a routing intent, the logical network topology template may be configured to include a logical routing element.

Abstract: Systems and methods of communicating between a plurality of hosts comprising one or more first hosts controlled by a first control plane and one or more second hosts controlled by a second control plane are disclosed herein. Each of the one or more first hosts runs at least one tunneling endpoint of one or more first tunneling endpoints, and each of the one or more second hosts runs at least one tunneling endpoint of one or more second tunneling endpoint. The method includes storing, at each of the one or more first hosts, a global list identifying at least the one or more second tunneling endpoints. The method further includes receiving a packet at one of the one or more first tunneling endpoints. The method further includes replicating, encapsulating, and transmitting the packet to each of the one or more second tunneling endpoints based on the global list.

Abstract: Example methods and systems for a network management entity to perform adaptive packet flow monitoring. One example method may comprise receiving a request to monitor a packet flow between a first virtualized computing instance supported by a first host and a second virtualized computing instance supported by a second host. The method may also comprise activating a first set of checkpoints by instructing the first host and/or the second host to monitor the packet flow using the first set of checkpoints. The method may further comprise: in response to detecting a predetermined event based on first performance metric information associated with the packet flow, activating a second set of checkpoints by instructing the first host and/or the second host to monitor the packet flow using the second set of checkpoints.
