  • Patent number: 7852853
    Abstract: Systems and methods for transmitting video are provided. The system determines the type of encoded video frames. Each of the video frames is then placed in a network transport packet. A priority level of the network transport packet is set based on the determined type of the video frame. The system can apply error correction coding to video frames of a lower priority level.

  • Patent number: 7843838
    Abstract: A method for tracing a communication route through a network coupling a first device with a second device is provided. A first signal is transferred from the first device to the second device to cause a plurality of intermediate devices to report first information concerning the first signal. The first information is processed to identify the intermediate devices as defining the communication route. The intermediate devices are configured so that a second signal, when transferred from the first device toward the second device, causes a subset of the intermediate devices to report second information concerning the second signal. The second signal is transferred from the first device toward the second device. The second information is processed to identify the subset of the intermediate devices as a portion of a sequence of the intermediate devices defining the communication route.

  • Patent number: 7623784
    Abstract: A method and a communication system are disclosed for automatically verifying the identity of a network connection in an optical communication network. Each network component of the optical communication network stores an identification code. For the method, one step includes positioning a read system proximate to one of the network components. With the read system in the proper position, another step of the method includes reading the identification code stored on the network component. Another step of the method includes verifying the identity of a network connection based on the identification code read from the network component by the read system. Another step of the method includes indicating the results of the verification using the read system. Based on the results of the verification, a field technician may verify the identity of a network connection before connecting or disconnecting a fiber optic cable or otherwise handling the network component.

  • Patent number: 7453795
    Abstract: A control system for a communication network stores a plurality of fault recovery plans that are respectively associated with a plurality of links. The control system processes a first control signal from the communication network indicating that one of the links has a fault, and in response, identifies one of the fault recovery plans that is associated with the one link having the fault and implements the one fault recovery plan. The control system receives a second control signal from the communication network indicating network information, and in response, recalculates the fault recovery plans. The recalculated fault recovery plans implement link-based fault recovery, sub-path based fault recovery, and path-based fault recovery. The recalculated fault recovery plans group links constituents into groups by QoS requirements and assign the groups to back-up routes based on the QoS requirements and the performance of the back-up routes.

  • Patent number: 7394988
    Abstract: A communication system receives information from a first communication link. The communication system transfers a free-space optical signal carrying the information and transfers a high-GHz wireless signal carrying the information. The communication system receives the free-space optical signal carrying the information and receives the high-GHz wireless signal carrying the information. The communication system assesses communication performance for the free-space optical signal and the high-GHz wireless signal, and based on the communication performance, selects between the free-space optical signal and the high-GHz wireless signal to provide the information. The communication system transfers the information to a second communication link based on the selection.

  • Patent number: 7203385
    Abstract: Methods and networks are disclosed for optimizing PMD measurements on an installed span of fiber. For a method of the invention, a light system transmits light over the installed fiber. A PMD measurement system measures PMD on the fiber over a time period based on the light. A temperature measurement system measures ambient temperatures of the fiber over the time period. The PMD measurements and the ambient temperature measurements are then processed to determine an optimal temperature range for performing future PMD measurements on the fiber. The optimal temperature range indicates the best temperatures to perform measurements, the best time of day to perform measurements, the best time of year to perform measurements (such as summer or winter), etc.
