Abstract: A packet-forwarding integrated circuit includes a control logic module and a selector block configured to produce a value indicating an incoming interface associated with a multicast data stream that meets stream health requirements, wherein the multicast data stream is one of a plurality of redundant multicast data streams each received on different incoming interfaces, wherein based on the value produced by the selector block the control logic module outputs data packets of the multicast data stream that meets stream health requirements received on the incoming interface, and discards data packets of other multicast data streams received on other incoming interfaces not indicated by the selector block. In response to detecting that a quality of one of the redundant multicast data streams has fallen below a configured threshold, the control logic automatically rewrites the selector block to forward a different one of the redundant multicast data streams.

Abstract: In general, this disclosure describes a high-level forwarding path description language (FPDL) for describing internal forwarding paths within a network device. The FPDL enables developers to create a template that describes a section of an internal forwarding path within the forwarding plane of a network device. The FPDL provides syntactical elements for specifying the allocation of forwarding path structures as well as enabling the run-time construction of internal forwarding paths to interconnect the forwarding path structures in a manner specific to packet, packet flow, and/or interface properties, for example. In conjunction with late binding techniques, whereby the control plane of the network device provides arguments to template parameters that drive allocation by the packet forwarding engines of forwarding path structures specified by the FPDL, the techniques provide control plane processes a unified interface with which to manage the operation of the packet forwarding engines.

Abstract: Embodiments of the current invention describe methods of forming different types of crystalline silicon based solar cells that can be combinatorially varied and evaluated. Examples of these different types of solar cells include front and back contact silicon based solar cells, all-back contact solar cells and selective emitter solar cells. These methodologies all incorporate the formation of site-isolated regions using a combinatorial processing tool and the use of these site-isolated regions to form the solar cell area. Therefore, multiple solar cells may be rapidly formed on a single crystalline silicon substrate for use in combinatorial methodologies. Any of the individual processes of the methods described may be varied combinatorially to test varied process conditions or materials.

Abstract: A network device provides a selector list that includes indices of child nexthops associated with the network device, where each of the child nexthops is associated with a corresponding child link provided in an aggregated bundle of child links. The network device also receives an indication of a failure of a child link in the aggregated bundle of child links, and removes, from the selector list, an index of a child nexthop associated with the failed child link. The network device further receives probabilities associated with the child links of the aggregated bundle of child links. Each of the probabilities indicates a probability of a packet exiting the network device on a child link. The network device also creates a distribution table based on the probabilities associated with the child links, and rearranges values provided in the distribution table.

Abstract: In an embodiment, a method comprises receiving a path advertisement comprising information about an available path and a well-known community value associated with the available path. A modified best path calculation is performed in response to receiving the available path either from a higher-ranked device or from a device that is not participating in diverse path calculation, resulting in creating a particular best path. The particular best path is advertised to other routers with or without a restriction indicator based on whether it is a client learned path or non-client iBGP peer learned path and based on whether the advertisement is directed to a client or a non-client iBGP peer.
