Abstract: A method includes managing a virtual machine (VM) in a cloud extension, where the VM is part of a distributed virtual switch (DVS) of an enterprise network, abstracting an interface that is transparent to a cloud infrastructure of the cloud extension, and intercepting network traffic from the VM, where the VM can communicate securely with the enterprise network. The cloud extension comprises a nested VM container (NVC) that includes an emulator configured to enable abstracting the interface, and dual transmission control protocol/Internet Protocol stacks for supporting a first routing domain for communication with the cloud extension, and a second routing domain for communication with the enterprise network. The NVC may be agnostic with respect to operating systems running on the VM. The method further includes migrating the VM from the enterprise network to the cloud extension through suitable methods.

Abstract: Techniques are provided for a management application in a first virtual network to start a first cloud gateway in the first virtual network. First messages are sent to a second virtual network, the first messages comprising information configured to start a second cloud gateway and a first virtual switch in the second virtual network. A connection is established between the first cloud gateway and the second cloud gateway, where the first cloud gateway, the second cloud gateway, and the first virtual switch form a first scalable cloud network element. One or more second messages are sent to the second virtual network, the one or more second messages comprising information configured to start a virtual machine and a first virtual machine interface configured to allow the virtual machine to access processing resources in the second virtual network. Data are stored that associates the virtual machine with the first virtual switch.

Abstract: The present invention relates to an algorithm for ensuring compliancy of an algorithm module when integrated in a real time software system. The compliancy tests may include a memory test, interrupt test, latency test and other tests, as well as combinations thereof. An inventive aspect of the present invention relates to a unit test harness for verifying that a software algorithm module meets performance and functional requirements when integrated in a complete real-time software system. A software algorithm module eliminates or reduces unwanted behavior by the caller or other software on a real-time software system due to incorrect operations, which may involve interrupts, memory usage, register usage and/or other factors.
