International Classification:

G06F 15/16

US Classification:

709232, 709233

Abstract:

An ISP-friendly rate allocation system and method that reduces network traffic across ISP boundaries in a peer-to-peer (P2P) network, Embodiments of the system and method continuously solve a global optimization problem and dictate accordingly how much bandwidth is allocated on each connection. Embodiments of the system and method minimize load on a server in communication with the P2P network, minimize ISP-unfriendly traffic while keeping the minimum server load unaffected, and maximize peer prefetching. Two different techniques are used to compute rate allocation, including a utility function optimization technique and a minimum cost flow formulation technique. The utility function optimization technique constructs a utility function and optimizes that utility function. The minimum cost flow formulation technique generates a minimum cost flow formulation using a bipartite graph have a vertices set and an edges set. A distributed minimum cost flow formulation is solved using Lagrangian multipliers.

US Classification:

370390

Abstract:

Described is a distributed peer-assisted multicast content delivery system (e.g., a multiparty conferencing application) that uses an adaptive link rate control protocol to discover and adapt to an arbitrary topology quickly and converge to efficient link rate allocations allowed by an underlying network. Link rates are regularly obtained and used to determine trees for sending packets to other nodes. Network coding is used to implement data multicast so that mixtures (i.e., linear combinations) of the packets are transmitted in the network. The redundant packets may be differentiated from non-redundant (“innovative”) packets such that network conditions may be measured by link innovation and/or session innovation.

International Classification:

H01L 27/146

Abstract:

An image sensor includes first and second pluralities of photodiodes interspersed among each other in a semiconductor substrate. Incident light is to be directed through a surface of the semiconductor substrate into the first and second pluralities of photodiodes. The first plurality of photodiodes has greater sensitivity to the incident light than the second plurality of photodiodes. A metal film layer is disposed over the surface of the semiconductor substrate over the second plurality of photodiodes and not over the first plurality of photodiodes. A metal grid is disposed over the surface of the semiconductor substrate, and includes a first plurality of openings through which the incident light is directed into the first plurality of photodiodes. The metal grid further includes a second plurality of openings through which the incident light is directed through the metal film layer into the second plurality of photodiodes.

International Classification:

US Classification:

709212

Abstract:

The subject disclosure is directed towards using primary data deduplication concepts for more efficient access of data via content addressable caches. Chunks of data, such as deduplicated data chunks, are maintained in a fast access client-side cache, such as containing chunks based upon access patterns. The chunked content is content addressable via a hash or other unique identifier of that content in the system. When a chunk is needed, the client-side cache (or caches) is checked for the chunk before going to a file server for the chunk. The file server may likewise maintain content addressable (chunk) caches. Also described are cache maintenance, management and organization, including pre-populating caches with chunks, as well as using RAM and/or solid-state storage device caches.
