Abstract: A network element configured to support Connectivity Fault Management (CFM) for Operation, Administration and Maintenance (OAM) includes circuitry configured to track faults in the CFM via a defect indication variable that includes multiple bits wherein each bit is one of a certain priority level of a plurality of priority levels and a reserved value, and, responsive to one or more of detection of a new fault and clearing of an existing fault, update the defect indication variable accordingly based on a corresponding priority level of the new fault or the existing fault.

Abstract: Systems and methods for enhancing the Connectivity Fault Management (CFM) protocol defined in IEEE 802.1Q are provided. In particular, the enhancements include adding a security or safety feature to prevent malicious attacks. A method, according to one implementation, includes the step of operating a Network Element (NE) in a safety mode associated with a link connectivity protocol (e.g., CFM) that involves receiving one or more messages used for detecting link connectivity issues of an Ethernet service in a section of a network and responding to the link connectivity issues. In response to receiving the one or more messages used for detecting link connectivity issues while operating the NE in the safety mode, the method includes the step of storing the one or more messages as one or more untrusted messages in an isolated database of the NE without processing information in the one or more untrusted messages.

Abstract: Systems and methods for tracking and reporting the existence or absence of faults in a Network Element (NE) or node of a network, network domain, or Maintenance Domain (MD) are provided. A method, according to one implementation, includes a step of tracking the existence or absence of a plurality of faults in a NE within a network domain. Each of the plurality of faults is categorized in one of a plurality of priority levels. In response to a detection of one or more new faults in the NE or a rectification of one or more old faults in the NE, the method further includes the step of updating a fault indication variable that individually signifies the existence or absence of a fault at each of the priority levels.

Abstract: Provided herein are filtration membranes for water treatment, and methods for preventing fouling of such membranes. The method described herein comprises grafting the membrane surface with an organic moiety, by reacting the surface with an organometallic reagent, a phosphonate, a phosphinate, or an organosilane.

Abstract: A film layer is disclosed that is capable of shrinking when subjected to energy, such as heat. The film layer, for instance, can be formed and then stretched in one or two directions at a relatively low temperature. In particular, the film is stretched while the film layer is at a temperature near the glass transition temperature of the polymer used to form the film. Drawing the film at a relatively low temperature has been found to improve the shrink properties of the film. In one embodiment, the film layer is comprised of a non-modified polyester, such as polyethylene terephthalate. For example, the polyethylene terephthalate can be made by reacting terephthalic acid with ethylene glycol or polyethylene glycol.

Abstract: System and method for extracting, retrieving and managing data in a computer or network of computers through an enhancement of the power of the directory management system and email management system by enabling users to superimpose a hierarchy of descriptors on top of the system, to share, import and export the hierarchy of descriptors between computers with controlled access for data objects. The method and system is defined particularly for selecting individual references from search engine results and saving them along with descriptors. The method and system automatically generate reports of work done in the computer or network of computers, including creation, modification, copying, moving and deletion of files and folders. The method and system reduces the clutter of information while ensuring that the system is automatically backed up in different modes and with complete flexibility to back up.

Abstract: A method includes identifying an initial solution to a quadratic programming (QP) problem associated with a process. The method also includes performing an iterative procedure having one or more iterations. Each iteration includes determining whether any constraint associated with the process is violated in the solution. Each iteration also includes selecting a violated constraint, determining a step direction and a step length associated with the selected violated constraint, and updating the solution based on the step direction and the step length. Determining the step direction and the step length includes using a Schur complement based on an active set of constraints associated with the solution. The Schur complement is nonsingular during all iterations of the iterative procedure except when the active set is empty.

Abstract: A method and system for enhancing the relevance and usefulness of information searches, such as web searches, by introducing individual and shared user's judgment; first, to define the universe of the search, automatically internalizing the content of that universe (via a copyright-compliant system) in an automatically updated repository that can integrate other (internally generated or imported) content and enable sharing according to user preferences; and, secondly, to organize the internalized content through tagging, book marking and filtering.
