In one embodiment, a system for managing a virtualization environment includes a set of host machines, each of which includes a hypervisor, virtual machines, and a virtual machine controller, and a data migration system configured to identify one or more existing storage items stored at one or more existing File Server Virtual Machines (FSVMs) of an existing virtualized file server (VFS). For each of the existing storage items, the data migration system is configured to identify a new FSVMs of a new VFS based on the existing FSVM, send a representation of the storage item from the existing FSVM to the new FSVM, such that representations of storage items are sent between different pairs of FSVMs in parallel, and store a new storage item at the new FSVM, such that the new storage item is based on the representation of the existing storage item received by the new FSVM.

Embodiments are directed to managing communication over one or more networks. A monitoring engine may be instantiated to perform actions including receiving network traffic from a physical network that may be associated with network addresses of the physical network. The monitoring engine may analyze the network traffic to associate activity with gateway identifiers (GIDs) associated with gateway computers in an overlay network such that the GIDs are separate from the network addresses. The monitoring engine may be arranged to monitor the network traffic based on monitoring rules. The monitoring engine may provide metrics associated with the gateway computers based on the monitoring of the network traffic. The monitoring engine may compare the metrics to event rules. The monitoring engine may generate events based on affirmative results of the comparison. The events may be mapped to actions based on characteristics of the events and executed.

This application provides a network performance monitoring method, a network device, and a storage medium, and belongs to the field of network technologies. In this application, a forwarding plane samples network performance data based on a fine-grained time periodicity, and records a quantity of network performance exceptions; and a control plane generates, based on a coarse-grained time periodicity, an alarm when the quantity of network performance exceptions recorded by the forwarding plane is greater than a threshold. On a basis of meeting a fine-grained requirement on network performance monitoring, because the control plane does not need to report all the collected network performance data, a volume of data that needs to be reported by the control plane is greatly reduced. This resolves a problem of overload of a main control CPU that is caused by massive data reporting, and reduces dependency of the network performance monitoring on performance of the main control CPU of a device. This further resolves a problem that a large quantity of bandwidth resources are occupied due to the massive data reporting, reduces dependency of the network performance monitoring on the bandwidth resources, and helps meet a requirement for deploying a large quantity of performance monitoring nodes in a live network.

A wireless device transmits a first message comprising a preamble and a transport block. The wireless device receives, during a time window, a first downlink control information (DCI) scheduling a response to the first message. The first DCI indicates a first transmit power control (TPC) command value. A decoding failure of the response and an expiry of a timing alignment timer is determined. The wireless device receives, based on the determining and during the time window, a second DCI rescheduling the response. The second DCI indicates a second TPC command value. The wireless device selects, based on a decoding success of the response rescheduled by the second DCI, the second TPC command value as a transmit power adjustment value among the first TPC command value and the second TPC command value. The wireless device transmits a feedback using a transmit power determined based on the transmit power adjustment value.

In one embodiment, a system for managing communication connections in a virtualization environment includes a plurality of host machines implementing a virtualization environment, wherein each of the host machines includes a hypervisor, at least one user virtual machine (user VM), and a distributed file server that includes file server virtual machines (FSVMs) and associated local storage devices. Each FSVM and associated local storage device are local to a corresponding one of the host machines, and the FSVMs conduct I/O transactions with their associated local storage devices based on I/O requests received from the user VMs. Each of the user VMs on each host machine sends each of its respective I/O requests to an FSVM that is selected by one or more of the FSVMs for each I/O request based on a lookup table that maps a storage item referenced by the I/O request to the selected one of the FSVMs.
