Abstract: A mechanism is disclosed for enabling load balancing to be achieved in a loop-free switching path, reverse path learning network, such as an Ethernet network. The network is divided into a plurality of virtual networks, with each virtual network providing a different path through the network. When it comes time to send a set of information through the network, one of the plurality of virtual networks, and hence, one of the plurality of paths, is selected. The set of information is then updated to indicate the selected virtual network, and sent into the network to be transported along the selected path. With multiple paths, and with the ability to select between the multiple paths, it is possible to balance the load imposed on the multiple paths.

Abstract: A digital PFC (DPFC) control approach that requires no input voltage sensing or current loop compensation is described. The approach can provide stable, low-harmonic operation over a universal input voltage range and load ranging from high-load operation in continuous conduction mode down to near-zero load. A fast voltage loop can also be incorporated into a DPFC controller to provide additional control of the power stage. A controller can be based on low-resolution DPWM and A/D converters, can be implemented without microcontroller or DSP programming, and is well suited for simple, low-cost integrated-circuit realizations.

Abstract: Methods and systems for shielding layer two host addresses (e.g., MAC addresses) from a network are provided. According to one embodiment, a border component of a network of switches receives a first packet intended for a first host having a first L2 address and a first L3 address associated therewith. The first packet includes the first L3 address and a substitute L2 address as destination addresses. The substitute L2 address is associated with a communication channel of the border component. A data structure including information regarding an association between the first L3 address and the first L2 address is accessed by the border component. A determination is made that the destination L2 address for the first packet should be the first L2 address. A first updated packet is derived from the first packet by replacing the substitute L2 address with the first L2 address and sent to the first host.

Abstract: Methods and systems for creating three-dimensional models from two-dimensional images are provided. According to one embodiment, a computer-implemented method of creating a polygon-based three-dimensional (3D) model from a two-dimensional (2D) pixel-based image involves creating an inflatable polygon-based 3D image and extruding the inflatable polygon-based 3D image. The inflatable polygon-based 3D image is created based on a 2D pixel-based input image by representing pixels making up the 2D pixel-based input image as polygons. The inflatable polygon-based 3D image is extruded by generating z-coordinate values for reference points associated with the polygons based upon a biased diffusion process.

Abstract: Methods are provided for managing hierarchically organized subscriber profiles. According to one embodiment, a policy engine of a VR defines services available to subscribers in terms of profile identifiers. A scalable subscriber profile database is established having a memory requirement dependent upon the number of available service contexts by hierarchically organizing profile identifiers as leaf profile identifiers, which explicitly define services, and intermediate profile identifiers, which indirectly represent services. The policy engine receives a first-level profile identifier and determines whether it is among those stored in the database. If not, then it obtains service profile information associated with the first-level profile identifier. If the first-level profile identifier is an intermediate profile identifier having leaf profile identifiers, then it further obtains them and associated profile information and stores this information in the database.
