摘要： A capability is provided for supporting a service location capability in a peer-to-peer network (P2P), such as a Chord network or other P2P network. In one embodiment, a method for locating a service within a P2P network is provided. The P2P network includes a plurality of nodes, including a target node which performs the method for locating the service within the P2P network. The target node includes a search table including a plurality of entries identifying a respective plurality of nodes of the P2P network. The method includes detecting a request to search for the service within the P2P network and initiating, toward at least one of the nodes of the search table, a service search request. The service search request is a request to identify at least one node of the P2P network that supports the service. The service search request includes information indicative of the service and a search range for use by the node receiving the service search request.

摘要： An application program interface (API) for a data platform. The API includes a generic data access component that exposes at least one of stores, sessions, transactions, and query services of the data platform, which data platform is associated with a data store. A data classes component of the API provides canonical, application-independent classes that expose types and relationships of a data model of the data platform. The API includes a domain data classes component of application-specific and framework-specific classes that expose domain-specific properties and behaviors of the data platform. The data platform can be a common data platform that interfaces to the data store to provide data services accessible by a plurality of disparate application frameworks, which data services allow a corresponding application of the different frameworks to access the data store.

摘要： In one embodiment, a method for setting up a flow-through mesh group (FTMG) for transmitting link-state packets (LSPs) in a network having a plurality of nodes interconnected by links. The FTMG is a combination of multiple spanning trees for the network through which LSPs are forwarded. FTMG set-up messages are received at ports of each node of the network from peer ports of linked nodes. FTMG set-up messages identify root nodes of the multiple spanning trees and the transmission modes of the peer ports. The FTMG set-up messages are used to determine (1) a root node for each spanning tree, (2) a root port on each node for each spanning tree, and (3) directionality of ports of the nodes. FTMG set-up messages are then used to determine the transmission mode of ports of the nodes and, subsequently, to update the spanning trees and transmission modes, as needed.

摘要： A restoration path planner minimizes cost while meeting restoration-time constraints of a network by reducing the worst-case number of cross-connections that must be performed in a network in the event of a single element failure. The planner involves optimization that identifies primary and restoration path plans for demands within the network such that the worst-case number of cross-connections at any node within the network is minimal and/or bounded. Embodiments further constrain the cost of the path plan. In one embodiment, restoration time is bounded and cost is relaxed until a solution is found. In another embodiment, the restoration time bound is relaxed to a limit while path plans and their costs are stored. These plans can later be chosen amongst for the desired balance of cost and restoration time. At least one approach to minimization of network cost involves maximizing sharing within restoration path plans.

摘要： A method and system to convert an image described in a page description language to a contone image. The contone image is halftoned and encoded to generate image data including edge tag data and image data. A tagged state value of each pixel of image data within a predefined neighborhood of pixels is determined. The image data is filtered using a predetermined set of filter weighting values wherein each pixel of image data within the predefined neighborhood of pixels has an associated filter weighting value. A predetermined filtered image value is assigned to each pixel having a tagged state indicating an edge pixel. A summation of all filtered image values for the predefined neighborhood of pixels is assigned when the tagged state of the pixel is a non-edge pixel.

摘要： What is provided herein is a novel system and method for estimating the amount of color in a document. In one embodiment, a binary CMYK input image is received. Each of the CMYK plane is received at an offset from the previous plane, i.e., the 4 planes are not received simultaneously. Each plane is divided into M×N tiles. Pixel values of all four planes are examined separately and the number of on-pixels is counted for each plane. The number of on-pixel counts for each tile are aggregated for each plane. Total on-pixel counts are used to estimate the total number of white, black, color, and gray pixel counts. The total counts for all planes are used to estimate the amount of color. A document is determined to be color if the amount of color exceeds a predetermined threshold. A color billing strategy is determined based on the estimated color amount.
