Abstract: Various aspects of the disclosure relate to beam information for independent links. For example, beam information for one link may be sent on at least one other link. In some aspects, the independent links may involve a first device (e.g., a user equipment) communicating via different independent links with different devices (e.g., transmit receive points (TRPs) or sets of TRPs). For example, the first device may communicate with a second device (e.g., a TRP) via a first link and communicate with a third device (e.g., a TRP) via a second link. In some scenarios, one link can indicate beam switching for at least one other link. In some scenarios, one link can indicate link recovery for at least one other link. In some scenarios, one link can indicate link failure for at least one other link.

Abstract: Embodiments of the apparatus for reducing latency in a flexible parser relate to an implementation that optimizes each parser engine within the parser. A packet enters the parser. Each of the parser engines processes the packet if processing is required. Otherwise, the parser engine simply forwards the packet through without processing the packet, thereby reducing latency. Each parser engine includes a memory. The memory stores bypass data and status information that indicates whether parsing for this packet is completed and, thus, no further processing is required by subsequent parser engines. Each parser engine also includes a counter, which is incremented whenever a packet enters the parser engine and is decremented whenever a packet exists the parser engine. A packet bypasses the parser engine based on the counter of the parser engine and the status information of that packet.

A state machine transitions between search states corresponding to one or more of the rules in accordance with contents of the input traffic stream and the conditions specified by the sequence of state definitions.

A terminal apparatus B which has received loop connection detection information from upstream determines whether or not a downstream terminal apparatus of a control path which is not a distribution route along which contents information is flowing, and a source of the loop connection detection information match and, in the event that they match, determines that a loop will occur. By this means, it is possible to determine in advance that a loop will occur, before switching an upstream connection destination.

Abstract: An architecture, system and method are provided for efficiently transferring packets of data across a communication network. Portions of the communication network is structured such that there are hierarchical levels of high speed Routing Switches existing throughout the network. Distributed routing of packets is achieved by comparing identification numbers of Routing Switches with the destination address of a data packet. Once routing is achieved within the transport ID based network, transfer to a destination termination device occurs through a single look-up table only when departing the network. The routing operation between termination devices can therefore be achieved using a single mapping operation and is backward compatible with devices external to the network and protocols used by those devices.

The deterministic access method enables QoS prioritization for periodic data flows such as those used in streaming media or VOIP communications without the direction of a central controller. The method provides a way for network nodes to schedule communications that take into account the hidden node problem, provide priority access to the communication medium for high QoS data flows, and provide shared access to the medium for lower priority data packets during unscheduled times. The method also enables both backward and forward compatibility with network communication methods as well as interoperability between mesh networks and conventional networks.

Abstract: The invention relates to a method for reception of a data stream, transmitted in segment in one or several broadcast channels, comprising a reception step for the data in a segment of data stream transmitted by an active broadcast channel. A step for changing reception channel allows switching from the current broadcast channel to a second channel after receipt of the data stream. A listening step on said second channel listens for an event identifying the transmission of the subsequent segment of the data stream and a step for changing reception channel by switching from said second channel to the current broadcast channel or another broadcast channel.

Abstract: A link aggregation function and maintenance function by MPLS OAM. Identical entry information is stored in plural circuits IF which perform a LA setting. In this way, multiplexing to the same LSP is possible even with different IF. The first network IF is assumed to be OAM ACT, and the second network IF is set to OAM SBY (SBY). OAM frame insertion is performed only by an OAM ACT port. In this way, in an opposite MPLS transmission apparatus, it is possible to prevent CV frame reception above a specified number of frames. Further, a switch forwarding table is set to forward frames from the network side to the first network IF of OAM ACT. The second network IF which was set to OAM SBY does not perform fault detection by CV reception. In this way, incorrect detection of faults due to non-reception of OAM can be prevented.

Also, in the event of simultaneous arrival of at least two pilot signals at the respective star interfaces, a decision circuit releases one star interface for the transmission of data.

Abstract: Each mobile ad hoc node has an assigned hierarchy position within an identified tree-based aggregation group. Each ad hoc node is configured for selectively attaching to one of a plurality of available ad hoc nodes based on identifying a best match, for the assigned hierarchy position within the identified aggregation group, from among identifiable hierarchy positions of identifiable aggregation groups. Each ad hoc node also is configured for selectively attaching to any available ad hoc node based on a determined absence of any available ad hoc node advertising the identified aggregation group of the ad hoc node, or an aggregation group containing the identified aggregation group. Hence, a root node of an aggregation group can filter group-specific routing information from packets destined toward a network clusterhead, resulting in a scalable routing protocol that is not adversely affected by added nodes.
