A software switch and a method performed by the software switch are disclosed. The software switch receives, from a node deploying a virtual machine, a request for a virtual port to be polled by the virtual machine. The request includes a Central Processing Unit 'CPU' identity identifying a CPU on which the virtual machine executes. The request includes an indication of a clock frequency at which the CPU is set to operate. The software switch determines a number of packets in a queue associated with the virtual port. The software switch adjusts the clock frequency of the CPU based on the number of packets in the queue. A corresponding computer program and a computer program carrier are also disclosed.

Software switch and method therein

A method is implemented by a network device for orchestrating execution of a polling thread of a software-based switching program on a heterogeneous multicore processor. The method includes causing the polling thread to be executed on a first processing core in a first cluster of a plurality of clusters of processing cores, determining a value indicative of a number of active processing cycles used by the polling thread, determining whether the value is higher than a high threshold associated with the first processing core or lower than a low threshold associated with the first processing core, and if so causing the polling thread to be moved to a second processing core in a second cluster of the plurality of clusters, where the second processing core has a different processing capacity than the first processing core.

Efficient mechanism for executing software-based switching programs on heterogenous multicore processors

A method in a first network device of performing a software update of a line card of a second network device without disruption to data traffic. The method includes causing a redundant control plane component of the second network device to be updated according to the software update. The method continues with causing the second network device to instantiate, based on the software update, a line card virtual machine (LC VM) as a redundant data plane component for the line card. The method further includes causing a third network device to forward data traffic to both the line card and the LC VM of the second network device, and causing the second network device to update the line card according to the software update while processing the received data traffic using the LC VM.

Method and apparatus for performing hitless update of line cards of a network device

Various embodiments of systems and methods for replicating data included in a portable electronic device to a new portable electronic device are described herein. Initially a copy of data, including an application, stored in the portable electronic device is generated. Next a determination is made whether the application is included in an application distribution platform corresponding to an operating system of the new portable electronic device. Finally based on the determination, the application is downloaded from the application distribution platform to the new portable electronic device.

Data replication among portable electronic devices

Various embodiments of systems and methods for dynamically switching device configuration based upon context are described herein. In an aspect, the method includes reading a tag attached to an entry gate of a restricted area through a device. Upon reading the tag, an application is executed to connect the device to a mobile device management (MDM) server. Upon establishing the connection, the restricted area identifier (ID) is sent to the MDM server. The device receives one or more policies applicable for the restricted area from the MDM server. The received one or more policies are executed on the device to change the device configuration. After execution, the device sends a confirmation message to the MDM server to indicate that the device is policy complaint. Upon receiving the confirmation, the MDM server instructs to open the entry gate to allow the device within the restricted area.

Context based dynamically switching device configuration

Various embodiments of systems and methods to provide memory management of a device accessing applications are described herein. In one aspect, a request is received to access an application on a device. Further, a check is performed to determine whether the application is enterprise application or personal use application. When the application is personal use application, access to the application is provided by installing the personal use application on the device. The personal use application utilizes at least a portion of an available general memory and a portion of an available corporate memory in the device.

Memory management of a device accessing applications

Exemplary methods for upgrading route processor virtual machines (RP VMs) and line card virtual machines (LC VMs) include upgrading a second RP VM serving as a standby RPVM with a new RP VM image. The methods further include spawning, using a new LC VM image, a second set of LC VMs to serve as standby LC VMs. The methods also include performing incubation of standby VMs, by configuring a switch to forward data traffic to both the first and second set of LC VMs, thereby allowing system states of the standby VMs to be auto-populated by the data traffic. The methods further include, after the incubation has completed, swapping roles of VMs at the virtual router, such that data traffic are exchanged only between the switch and the upgraded VMs.
