20130283364 | DISTRIBUTED VIRTUAL SWITCH ARCHITECTURE FOR A HYBRID CLOUD - In one embodiment, a secure transport layer tunnel may be established over a public network between a first cloud gateway in a private cloud and a second cloud gateway in a public cloud, where the secure transport layer tunnel is configured to provide a link layer network extension between the private cloud and the public cloud. In addition, a cloud virtual Ethernet module (cVEM) may be executed (instantiated) within the public cloud, where the cVEM is configured to switch inter-virtual-machine (VM) traffic between the private cloud and one or more private application VMs in the public cloud connected to the cVEM. | 10-24-2013 |

20130268643 | SYSTEM AND METHOD FOR MIGRATING APPLICATION VIRTUAL MACHINES IN A NETWORK ENVIRONMENT - 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. | 10-10-2013 |
20130297769 | SYSTEM AND METHOD FOR SIMULATING VIRTUAL MACHINE MIGRATION IN A NETWORK ENVIRONMENT - A method includes simulating network resources of a portion of a cloud in a simulated cloud within a enterprise network, the cloud being communicable with the enterprise network over a first communication channel, which may be external to the enterprise network. The method can also include simulating network behavior of the first communication channel in a second communication channel within the enterprise network, and validating application performance in the simulated cloud. Simulating network resources includes providing a cloud resources abstraction layer in the enterprise network, and allocating enterprise network resources in the enterprise network to the simulated cloud by the cloud resources abstraction layer. The method further includes adding a virtual network service appliance to the simulated cloud, and determining a change to a network topology of the enterprise network to accommodate the virtual appliance without materially impacting application performance. | 11-07-2013 |
20140366155 | METHOD AND SYSTEM OF PROVIDING STORAGE SERVICES IN MULTIPLE PUBLIC CLOUDS - A system and a method implement a cloud storage gateway configured to provide secure storage services in a cloud environment. A method can include implementing storage provisioning for a virtual machine (VM) in a hybrid cloud environment that includes an enterprise network in communication with a cloud. Enterprise network includes enterprise storage, and cloud includes cloud storage. The storage provisioning is implemented by deploying a cloud storage gateway in the cloud that facilitates secure migration of data associated with the VM between enterprise storage and cloud storage. A nested virtual machine container (NVC) is also deployed in the cloud, where NVC abstracts an interface that is transparent to a cloud infrastructure of the cloud. Cloud storage gateway can then be executed as a virtual machine within NVC. Such storage provisioning is further implemented by deploying the VM in a NVC in the cloud and directly attaching storage to the VM. | 12-11-2014 |

20150181430 | SYSTEMS AND METHODS FOR COMMUNICATION USING A BODY AREA NETWORK - The present disclosure relates to computer-implemented systems and methods for establishing communication using a body area network. A system may receive, by a capacitive sensor, a touch interaction from a user. Furthermore, the system may determine, by the capacitive sensor based at least in part on the touch interaction, a change in capacitance. In addition, the system may transmit, via the user's body in response to the change in capacitance, a request to a user device for credential information. The system may also receive, from the user device via the user's body, the credential information. | 06-25-2015 |
