摘要:
A compute infrastructure interconnected with a network configured for allotting a benchmark message. The benchmark message comprises program code, or references to program code, to be executed on a reflecting entity. The reflecting entity is able to execute program code. The program code requests capabilities of the reflecting entity when being executed. The compute infrastructure is further configured for sending of the benchmark message to the reflecting entity. The compute infrastructure is further configured for receiving the benchmark message and for executing, in the reflecting entity, the program code. The compute infrastructure is further configured for providing a benchmark reply message. The benchmark reply message comprises execution time and optionally execution result of the execution of said program code. The compute infrastructure is further configured for returning the benchmark reply message from the reflecting entity.

The invention relates to a visualization platform (9) arranged to provide at least one virtual operating system instance (9A, . . . , 9N) to at least one remote network (3) over a packet-based communication network (5). The visualization platform is characterized in that it comprises at least one first termination point (4b) of a virtual private network VPN tunnel (10) which enables the establishment of at least one VPN tunnel between said at least one first termination point and at least one second termination point (4a) in said at least one remote network over said packet-based communication network; and in that it is arranged to map said at least one virtual operating system instance to said at least one first termination point of said at least one VPN tunnel. The invention also relates to a method for virtualization and a computer program product.

A method performed by a hypervisor executing a virtual machine for enabling a performance measurement between the virtual machine and a peer node, and a method performed by a physical machine comprising the hypervisor are provided. The method performed by the hypervisor comprises intercepting a packet transmitted from, or destined to, the virtual machine, the packet comprising a destination address to the virtual machine or to the peer node, and determining whether to insert a hypervisor time stamp or not in the packet. The method further comprises, when it is determined to insert the hypervisor time stamp in the packet, inserting a hypervisor time stamp in the packet, and forwarding the packet to its destination according to the destination address.

A network node is arranged to provide an end user of a network terminal in a network with an access link to an external network including at least one external network interface, a control unit, and at least one internal network interface, the network node being arranged to be connected between the network and the external network. The network node is characterized in that the control unit is arranged to deactivate and re-activate the at least one internal network interface towards the network terminal in the network in order to trigger a dynamic host configuration protocol request from the network terminal such that a new Internet Protocol configuration can be established for the network terminal. A method for use in a network node and a computer program product are also disclosed herein.
