    摘要： Minimum cost networks, such as fiber optic networks used in telecommunications, are obtained by defining available network elements having cost, required pairs, connectivity and penalty cost values and selecting from these available elements using an iterative rounding approximation method that constructs an LP relaxation incorporating the element parameters, finds an optimal basic solution, applies a selection criterion to pairs and edges in the optimal basic solution, and constructs a residual LP relaxation with selected pairs and edges. By fixing selected pairs and edges values to 1 in the residual LP, successive iterations of the method provide a design which is a 3-approximation solution to the minimum cost design problem.

    摘要： High dynamic range imaging includes creating a high dynamic range image file for a subject image captured from a first angle. The high dynamic range image file is created by an image capturing device and is stored on the image capturing device. High dynamic range imaging also includes receiving, at the image capturing device over a communications network, a second high dynamic range image file for the subject image captured from a second angle. The second high dynamic range image file is subject to an authorization requirement. High dynamic range imaging further includes creating, by the image capturing device, a composite high dynamic range image file by combining elements of both of the high dynamic range image files, and generating, by the first image capturing device, a three-dimensional high dynamic range image from the composite high dynamic range image file.

    摘要： A method is provided for monitoring devices with changing IP addresses. SNMP trap is received from a device at a first IP address to notify that a connection is up, and a SNMP poll is transmitted to the device to obtain an identifier. Predetermined consecutive SNMP GET requests are transmitted to the device in intervals. Responsive to failing to receive from the device predetermined consecutive SNMP GET responses equal to the predetermined consecutive SNMP GET requests, it is determined that there is a connection failure or a device failure and checked whether the device is in a maintenance window. If not in maintenance window, a trouble ticket is generated. Responsive to the failure, there is a predetermined waiting period for another SNMP trap from the device with a second IP address and the same identifier notifying that a connection is back up, and no trouble ticket is generated.

    摘要： A method is disclosed for monitoring a communication link between a first apparatus and a second apparatus, the method comprising receiving concurrently from the first apparatus (e.g., a central office) at the second apparatus (e.g., an optical demarcation point at a customer premises) a communication signal at a communication wavelength, λ1 and a test signal at a test wavelength λt, permanently separating the test signal from the communication signal at the second apparatus and sending to the first apparatus on a return path between the first apparatus and the second apparatus a signal indicating whether the test signal was received at the second apparatus. An apparatus is disclosed including an interface for receiving concurrently the communication signal and the test signal, a filter for permanently separating the test signal from the communication signal and a coupler for permanently placing a signal on a return path.

    摘要： A system and method for sharing annotations corresponding to media content among a plurality of members of a group over a communications network. The system generally includes at least one server coupled to the communications network and configured for receiving at least one annotation from a first group member corresponding to media content from the communications network; adding the at least one annotation to a database; accessing a list of members of the group, each member of the group having a user profile stored in memory; and automatically sending a notification to at least a second member of the group upon receipt of each annotation. The annotation comprises annotation content and a temporal identifier that identifies a segment of the media content to which the annotation corresponds, and the at least one server is configured for sending the annotation to at least the second group member and optionally a media stream including at least the segment of the media content with the annotation.

    摘要： A technique for examining the relationships of autonomous systems (ASes) participating in an Internet Exchange Point (IXP) utilizes packet tracing servers proximate the IXPs. Where such packet tracing servers cannot be found in the participating ASes, the methodology identifies additional vantage points by looking at a list of ASes that are one hop away from the ASes at the IXP. The choice of one-hop away ASes is made judiciously by picking ones that have better connectivity, based on past-data. Plural-hop ASes may also be used where necessary.
