Abstract: Techniques are described to provide multicast service within a virtual network using a virtual network controller and endpoint replication without requiring multicast support in the underlying network. The virtual network controller is configured to create a multicast tree for endpoint devices of a multicast group in the virtual network at a centralized location instead of in a distributed fashion. The virtual network controller communicates the multicast tree to one or more of the endpoint devices of the multicast group to instruct the endpoint devices to replicate and forward multicast packets to other endpoint devices according to the multicast tree. The replication and forwarding of multicast packets is performed by virtual switches executed on the endpoint devices in the virtual network. No replication is performed within the underlying network. The techniques enable multicast service within a virtual network without requiring multicast support in the underlying network.

Abstract: In one example, a network device includes a virtual network agent, and a network interface to send network packets to the virtual network controller using a default route for a physical network prior to establishing a communication session between a virtual network controller and the virtual network agent, wherein, after establishing the communication session between the virtual network controller device and the virtual network agent, the virtual network agent receives from the virtual network controller a command to install a new route at the network device, wherein the new route specifies encapsulation information to use for encapsulating network packets for sending the network packets to the virtual network controller over an overlay network, and wherein, responsive to detecting a failed link in the physical network, the virtual network agent sends packets to the virtual network controller on an alternate route in the overlay network.

The devices have the benefits of a low profile mechanism (for both self-expanding and balloon-expanding prostheses), contained, not open, release of the material, active conformation to the “leak sites” such that leakage areas are filled without disrupting the physical and functional integrity of the prosthesis, and on-demand, controlled activation, that may not be pressure activated.

Abstract: Model element characteristic preservation is provided when instantiating unified modeling language elements of a unified modeling language model. Requirements management tool elements become associated with a stereotype via, for instance, user assignment of the stereotype to a requirements type of the requirements management project. A stereotype assignment is obtained for a requirements management tool element, and the stereotype is automatically applied when instantiating a UML element representative of the requirements management tool element. Nesting and traceability relationships between the requirements management tool element and other requirements management tool elements are additionally preserved.

Abstract: In general, techniques are described for facilitating multi-tenancy of a server accessed by virtual networks of a data center. A device included within a data center comprising one or more processors may perform the techniques. The processors may be configured to execute a virtual switch that supports a number of virtual networks executing within the data center. The virtual switch may be configured to receive a request regarding data associated with an identifier that is unique within one of the virtual networks that originated the request. The virtual switch may then translate the identifier included within the request to generate a globally unique identifier that is unique within the plurality of virtual networks, update the request to replace the identifier included within the request with the globally unique identifier, and transmit the updated request to a server of the data center.

Abstract: Described are methods and apparatuses, including computer program products for utilizing emergency procedures to determine location information for a Voice Over Internet Protocol (VOIP) device. A wireless access gateway (WAG) determines location information of the VOIP device and stores the location information. A request for a location of the VOIP device from a Mobile Switching Center (MSC) is received by the WAG. The WAG translates the stored location information into a format used by the MSC to receive location information from a Radio Access Network (RAN). The WAG provides the translated location information to the MSC.

The predictive control module detects that a first cylinder of an engine of the vehicle is deactivated while a second cylinder of the engine is activated. The predictive control module activates the first cylinder based on the grade.

Abstract: A system for heated gas fusing of toner on non-porous substrates is provided. The system uses (1) an extended fusing zone held at lower temperatures than needed for a roll nip or radiant fuser, and (2) a very low melt toner which can be fused at greatly reduced temperatures compared to conventional toners. In one form, the system is realized through (a) the use of heated gas as the low temperature extended zone fusing technology, and (b) the use of ultra-low melt (ULM) toner—which requires significantly reduced temperature compared to conventional toner. On non-porous packaging substrates the use of heated gas can limit the substrate temperature to 100° C.
