Abstract: A first network device includes a host and a memory. A media access controller receives data from the host and stores the data in the memory at a first rate. A physical-layer device receives the data from the memory and transmits the data from the first network device to a second network device. The memory is connected between the media access controller and the physical-layer device. An amount of the data stored in the memory is based on the first rate and a second rate at which the physical-layer device transfers the data from the memory to the second network device. The first rate is greater than the second rate. A control circuit, based on an amount of the data stored in the memory, transmits a first frame to the media access controller. The media access controller, in response to the first frame, decreases the first rate.

Abstract: In one embodiment, a local network device transmits a connectivity verification protocol control message over a link to a remote network device to attempt to establish a connectivity verification protocol session with the remote network device. In response to non-receipt of a returned connectivity verification protocol control message from the remote network device, the local network device determines that there is an inability to establish a connectivity verification protocol session with the remote network device. The local network device then sends a connectivity verification protocol echo message over the link to the remote network device without establishment of a connectivity verification protocol session. The echo message is sent using a forwarding protocol.

Abstract: Systems and methods described herein are directed to solutions for Network on Chip (NoC) interconnects that automatically and dynamically determines the number of layers needed in a NoC interconnect system based on the bandwidth requirements of the system traffic flows. The number of layers is dynamically allocated and minimized by performing load balancing of the traffic flows between the channels and routes of different NoC layers as they are mapped. Additional layers may be allocated to provide the additional virtual channels that may be needed for deadlock avoidance and to maintain the isolation properties between various system flows. Layer allocation for additional bandwidth and additional virtual channels (VCs) may be performed in tandem.

Abstract: Each node of a telecommunications network determines a connection type attributes available for each signal type supported by the node. Each signal type represents a different connection routing layer within the telecommunications network. Adaptation costs involved in traversing from one connection routing layer to another connection routing layer in the node are calculated. The connection type attributes and adaptation costs are included in a link state advertisement broadcasted by each node in the telecommunications network. A route calculation is performed for a desired signal to determine a route through the telecommunications network for the signal. The route calculation takes into account the various connection type attributes, availability, and adaptation costs in determining the shortest route for the signal through the telecommunications network.

The method includes, at an intermediate node of the network, intercepting at least one message sent to or from the data requesting node, the message(s) relating to data source node suitability, determining a cost of communication between the data requesting node and each of the data source nodes to which the message(s) relate, and influencing data source node suitability information sent to the data requesting node to take account of the cost to enable the data requesting node to use the information to select a data source node.

Abstract: A wireless communication receiver receiving a multiplexed signal comprising two or more signal streams calculates a received signal quality for the multiplexed signal as a function of stream-specific received signal qualities, determines one or more loss parameters indicative of variations in the stream-specific received signal qualities, and generates quality feedback based on such information. In turn, a transmitter controls the selection of one or more transmission parameters of the multiplexed signal based on the quality feedback, such that its transmit link adaptations account for the losses in received signal quality at the receiver arising from the variations in the stream-specific received signal qualities. The quality feedback may include calculated loss values, or parameter/penalties that permit loss calculation, and the method applies to both code multiplexing and spatial multiplexing.

Abstract: Packets in a multi-hop wireless network are routed based on the available link throughputs, network node congestion and the connectivity of the network in a manner that minimizes the use of radio resources and minimizes delay for packets in multi-hop system. The routing method also avoids congestion in the access network, especially near the network access points as provided by network access nodes. Each wireless network node maintains a link table for storing link conditions and associated route costs. Packets are routed according to the low cost route. Subsequent wireless network nodes evaluate whether a lower cost route is available and, if so, route the data packet according to the lower cost route. Every wireless network node transmits the data packet, a specified route and a time stamp indicated a time of the last data entry in the link table that was used to calculate the low cost route.
