Abstract:
A system and method for redundant synchronizing to a reference clock for data communications. A determination is made whether a first data stream and a second data stream are available. The first data stream and the second data stream are received through opposing directions of a communications ring. A first data packet and second data packet are received at a remote node in response to the first data stream and second data stream being available. A timing characteristic of the first data packet and the second data packet correspond to a tick of a reference clock. The tick of the reference clock is extracted utilizing a timing characteristic of the first data packet or second data packet in response to the first data stream or the second data stream being available. A secondary clock is disciplined with the reference clock by adjusting the secondary clock based on a difference between times measured by the reference clock and the secondary clock to generate a clock signal. The clock signal is communicated to one or more interfaces for distribution.
Abstract:
A set-top box may include a storage unit, input/output (I/O) unit configured to communicate with a network node of a service provider over a communications network, memory unit, and a processing unit in communication with the storage unit, I/O unit, and memory unit. A user control panel module may be executed by the processing unit and configured to cause the processing unit to present a graphical user interface to a user to control access to one or more content stores of a content mall operating on the network node. A service provider control panel module may be executed by the processing unit and be configured to cause the processing unit to enable the communications service provider to control operation of the processing unit. A codec module may be executed by the processing unit and configured to enable the processing unit to display content downloaded from a content store of the content mall.

Abstract:
A system and method for authorizing test traffic over a network. A request is received to perform a throughput test. A state of the network is determined. The throughput test is authorized in response to the determined state of the network being acceptable for performing the throughput test. The throughput test is terminated in response to the determined state of the network being unacceptable for performing the throughput test.
Abstract:
A system and method for monitoring bursting traffic of a user. CIR tokens are incremented at a first rate. EIR tokens are incremented at a second rate. At bit is received for communication through a user network interface. A determination is made whether there are EIR tokens in response to a determination that there are no CIR tokens. The EIR tokens are decremented in response to a determination that there are EIR tokens. The bit is communicated through a network in response to the determination that there are EIR tokens.
Abstract:
A system and method for providing content providers with network distribution nodes for distributing content to subscribers of a communications service provider may include maintaining multiple network nodes by the communications service provider, where the network nodes may be in communication with the Internet and be configured to enable subscribers of the communications service provider to access and download content without the content having to be communicated over the Internet. Multiple respective content service providers may be enabled to store content at the network nodes for subscribers local to each respective network node to download the content. Multiple customer databases configured to store information associated with subscribers of the communications service provider may be operated. Limited access to the information stored in the customer databases may be provided to prevent the respective content providers from accessing personal information of the subscribers.
Abstract:
A method of determining the state of a path in a network includes measuring at a node of the network a rate of throughput over an interval for at least a portion of the path and determining at the node of the network a derivation associated with a characteristic of the frames communicated over at least the portion of the path. The method also includes determining a state of congestion of the path in response to the measured rate of throughput and the determined associated derivation.
Abstract:
A system and method for broadcasting content as IPTV may include receiving broadcast feed content. The broadcast feed content may be converted into a first data format for broadcasting to set-top boxes. The broadcast feed content may be converted into a second data format for broadcasting to mobile devices. The converted broadcast feed content may be broadcast to set-top boxes and mobile devices in the first and second data formats, respectively.
Abstract:
A system, method, and optical switch for communicating timing. A determination is made whether one of a number of data streams are available. Packets are received at a remote node in response to determining one of the number of data streams is available. A timing characteristic of the at least one of the packets is associated with a tick of a reference clock. The tick of the reference clock is extracted utilizing the timing characteristic of the at least one of the packets. A secondary clock is disciplined with the reference clock by adjusting the secondary clock based on a difference between times measured by the reference clock and the secondary clock to generate a clock signal. The clock signal is communicated to one or more interfaces for distributing.

Abstract:
A system and method for monitoring user traffic. An observance window is established for a time period associated with the CIR rate. Incoming bits are measured to determine if the CIR rate plus a CBS rate is exceeded. A determination is made whether there is a threshold crossing during the observance window. A flag state is set indicating a user traffic flow is out of conformance in response to determining there is a threshold crossing.
