Abstract: A method for virtual segmentation off-load in a logically partitioned data processing system is provided. A data transmission protocol stack formats a data message for segmentation off-load to form a virtual segmentation off-load package. The size of the data message is larger than a size of a maximum transmission unit. A partition manager firmware copies the virtual segmentation off-load package from a first logical partition to a virtual Ethernet adapter associated with a second logical partition. The virtual segmentation off-load package is copied without performing a segmentation operation on the data message associated with the virtual segmentation off-load package.

Abstract: A rapid method and apparatus for remapping the type of service (TOS) and source address information from an incoming communications packet according to the desired Quality of Service (QoS) required for the communications flow into a switch or router are described. The input source address field of the packet header is used to access a lookup table of corresponding source autonomous system (AS) labels. The appropriate AS label is combined with the input TOS yielding an intra-switch TOS optimized for the QoS appropriate to the received flow. Alternatively, the netID, a subset of the source address, may be used directly without resort to a lookup table. As a further alternative, the destination address may be used in conjunction with the above. The resulting intra-switch TOS expedites packet management and throughput in the switch/router, facilitating the efficient delivery of the required Quality of Service for that flow.

Abstract: A self-organized and self-managed ad hoc network operates without the intervention of arbitration, collision detectors, hubs, master controllers, switches, or routers. The network may include both fixed and/or mobile stations. A self-organized and self-managed order of transmission sequence is automatically determined by the stations in the network, and then each station transmits in the order defined by that sequence. Stations can join in, or drop out of, the network at any time with little to no disruption of the network, and the transmission sequence is automatically updated to accommodate a joinder or removal.

Abstract: A flexible framing format and implementation scheme for transmitting uncompressed video data selected from a group of various video formats, audio data and control data over a single serial communication channel at a fixed clock rate, thereby eliminating the need for transmitting a pixel clock signal. The data is transmitted over the single communication channel in packets and recreated at the destination side. Blank pixels of the video data are completely suppressed so that only active pixels are transmitted over the single communication channel, thereby reducing communication bandwidth requirement of the channel.

Abstract: Techniques are provided for detecting an increase in congestion in a distributed ad hoc network architecture and transitioning from the distributed ad hoc network architecture to a cluster ad hoc network architecture when a sufficient increase in congestion is detected based on one or more congestion level indicator values (CLIVs). Other techniques are provided for detecting a decrease in congestion in cluster ad hoc network architecture and transitioning from the cluster ad hoc network architecture to a distributed ad hoc network architecture when a sufficient decrease in congestion is detected based on one or more congestion level indicator values (CLIVs).

Abstract: A communications system includes a plurality of radios that form a carrier sense multiple access (CSMA) wireless communications network and communicate non-packetized digital voice with each other. Each radio is operative for dividing the period following the end of a transmission into a sequence of time slots and determining whether an end of a conversation has occurred. If an end of a conversation has occurred, the system decides randomly or pseudo-randomly with probability p to start transmitting on the channel in that slot.

Abstract: There is disclosed, for use in a CDMA wireless network, a channel resource allocator for reallocating a data traffic channel in a soft handoff state to handle incoming calls from new mobile stations. The channel resource allocator includes an overhead channel controller for reconfiguring a data traffic channel as an overhead channel upon failure of an overhead channel element in a base transceiver station (BTS). The channel resource allocator determines if all data traffic channels of the BTS are in use. If so, the channel resource allocator determines whether any of the existing calls being serviced by the data traffic channels are in a soft handoff state in which the call is connected simultaneously to, two or more base transceiver stations. If so, the channel resource allocator drops the connection to the BTS in which the overhead channel failure occurred, thereby freeing up the data traffic channel.

Abstract: A de-rate matching device in a communication system divides received data into a plurality of blocks, and simultaneously de-rate-matches data in the respective blocks.

Abstract: A method of receiving data packets. In the method of receiving data packets, a determination is made as to whether a received data packet is received out of an expected order. If the determining step determines a received packet is out of the expected order, a time period is calculated to wait for one or more missing data packets based at least in part on an expected time of receiving the one or more missing data packets.

Abstract: A peer to peer network, a method, a computer program product for a new node joining the network and a computer readable medium are disclosed. The peer to peer network comprises a plurality of nodes and a new node. Each of the nodes has its own partner list. Each of the partner lists records nodes that are able to provide data to the owner of the partner list. The nodes recorded in the partner list are called the partners of the owner of the partner list. When the new node intends to join the network, each of the nodes of the network decides whether to accept the new node according to the number of its partners but not according to a random manner. The stability of the network can be enhanced and the load of the network can be balanced.

Abstract: The present invention provides a method and apparatus for detecting and decoding data. The method comprises: receiving a set of data signals from an external data source; detecting a size of said received set of data signals; decoding said received set of data signals; extracting a destination address from said set of data signals; comparing said destination address extracted from said data signals to a known data value; determining whether said received data signals should be received by a host circuitry based upon said comparison of said destination address extracted from said data signals to a known data value; generating at least one status signal alerting said host circuitry of said determination that said received data signals should be received by said host circuitry; and waking up said host circuitry upon a determination that said received set of data is addressed to said host circuitry.

Abstract: A mechanism for performing remote direct memory access (RDMA) operations between a first server and a second server. The apparatus includes a packet parser and a protocol engine. The packet parser processes a TCP segment within an arriving network frame, where the packet parser performs one or more speculative CRC checks according to an upper layer protocol (ULP), and where the one or more speculative CRC checks are performed concurrent with arrival of the network frame. The protocol engine is coupled to the packet parser. The protocol engine receives results of the one or more speculative CRC checks, and selectively employs the results for validation of a framed protocol data unit (FPDU) according to the ULP.

Abstract: A network enables a transfer path to be formed between nodes in the network so as to transfer frames. A terminal for transmitting frames located outside the transfer path, upon transmitting a frame through the transfer path, writes the transfer path selection information related to the transfer path and the output line information related to the output line from the terminating node of the transfer path in the frame according to the destination information set in the frame and transmits the frame to the destination. The starting node of the transfer path decides the transfer path used for transferring the frame according to the transfer path selection information set in the frame to transmit the frame while the terminating node of the transfer path decides the output line used to output the frame according to the output line set in the frame, thereby transmitting the frame to the output line.
