Abstract: A system capable of detecting data within user application streams to manage or control the chains. For example, the system can receive bandwidth information from the application, and based on that information, determine a level of network traffic caused by the application. Such bandwidth information can include any one or more of subscription information, information provided by an application running on a user device, information provided by an application function, and a detected application type. Based on the bandwidth information, the system can either determine a service chain route for the stream, or determine how to bill for the traffic caused by the application. For example, such determinations may be conducted dynamically based on previously determined if/then rules established by a user of the system.

Abstract: Various embodiments are described to enable multiple, independent communication networks to share in an autonomous and dynamic manner unlicensed wireless resources. Generally, this involves determining that a first network node (122) is using at least a portion of a wireless resource to provide network service to at least one remote unit (102). A second network node (123), under the control of a different network operator than the first node and desiring to use the wireless resource, sends the first network node, a request to relinquish use of at least a portion of the wireless resource. The second network node sends this request wirelessly, perhaps using the wireless resource itself. If the first network node grants the request, the second node may then begin using at least a portion of the relinquished resource to provide network service.

Abstract: A communication system provides one or more of congestion information and subscriber information to a broadcast applications server when the server receives a request to start a broadcast-multicast service in a coverage area. By providing the one or more of congestion information and subscriber information to the server, the server is able to make an informed, intelligent decision concerning blocking, unblocking, downgrading, or upgrading a broadcast-multicast flow of multiple broadcast-multicast flows requested for delivery to, or currently delivered to, the coverage area via a serving base station, and/or whether to add a new broadcast-multicast flow to the broadcast-multicast flows delivered to the coverage area.

Abstract: The present invention provides a subscriber device (10), method (1000, 1500), wireless router (30), and communication system (100). The communication system (100) includes at least one subscriber device (10) having a message generator (1612) for generating a message which includes an indicator of a receive/transmit switching time, and the wireless router (30) for communicating with at least one subscriber device, the wireless router having a scheduler (902), optimizer (904), and an allocation map generator (906), wherein the wireless router (30) prepares an efficient and optimized channel allocation map for transmission to the subscriber device (10) taking into account the indicator of the receive/transmit switching time for the subscriber device (10) and wherein the map indicates at least one allocated transmit time, in a form of a block, having a beginning and an end, for transmission by the subscriber device following a receive time.

Abstract: In a time-space-time switching network that provides connections at a hierarchy of data rates, a path-hunt arrangement effects establishment of a switched connection of a given bandwidth as a collection of a plurality of connections of smaller bandwidths of different sizes. Connections are first found at the highest rate of the hierarchy to satisfy as much of the given bandwidth as possible. Then, connections are found at the lower rates to satisfy any remaining unsatisfied bandwidth. The path-hunt uses a hierarchy of status tables, corresponding to the hierarchy of rates, for each time-switching element of the network. The tables have entries that define availability of time slots--representing bandwidth of the tables' corresponding rates--between that time-switching element and a space-switching stage of the network. Connections are provided at the highest rate by finding matching idle time-slot entries in the high rate status tables for the two time-switching elements involved in the connection.

Abstract: A time-division multiplexed circuit switch (100) handles different-size time-division multiplex frames (30, 40, 50) in a single, shared, time-space-time switching fabric. Both time slot interchange stages (131,141) and a time-multiplexed space stage (120) of the switching fabric receive a plurality of overlapping different-size frames in each incoming superframe (30) of a succession of superframes and interleave switching of the different-size frames through the switching fabric to create a succession of outgoing superframes each one of which also has a plurality of the time-division-multiplex frames of different-sizes but from a plurality of incoming superframes. Switching of every individual received frame of any size commences as soon as the entire individual frame is received.

Abstract: A switching system having a control network for establishment of a path and a data switching network responsive to the path determined by the control network for switching data between a plurality of input ports to a plurality of output ports. The control network is a self-routing network that is fabricated utilizing electronic devices; whereas, the data switching network is fabricated using photonic devices. The electronic network is of the butterfly architecture and the photonic network is of the cross-bar architecture. A translation circuit is utilized to convert the path determined through the self-routing butterfly control network for use in determining the path through the photonic cross-bar network.

Abstract: A packet switching architecture in which switching network nodes automatically determine nonblocking paths through a switching network in response to address information. The switching network comprises stages of broadcast and routing nodes. The broadcast nodes are responsive to the transmission of address information from an input port to create a plurality of paths through the switching network and to communicate on this plurality of paths the address information to the routing stages. Each of the routing switch nodes is responsive to receipt of address information to select one of the paths to an address-designated output port. The final path is established by the output port transmitting an acknowledge signal back through the switching network. Each node upon receipt of the acknowledge signal establishes the path through the itself.
