Packet communication device, packet communication system, packet communication module, data processor, and data transfer system
A transmit packet generated by a CPU 1 is held in a buffer 100a (100b). From among packets received from Ethernet 820a (820b), a packet, a destination of which is a communication device 800, is held in the buffer 100a (100b). A packet which should be transmitted is transmitted from a transfer judging circuit 200 to Ethernet 820a or 820b through a MAC unit 300a or 300b. If a transfer judging circuit 200 judges a packet from the Ethernet 820a to be a packet, a destination of which is another communication device, with reference to a destination MAC address, this packet is transferred to the Ethernet 820b through MAC 300b. If a usage rate of a transferring FIFO buffer 130a (130b) exceeds a threshold value in the process of transmitting a packet held in a transmitting FIFO buffer 120a (130b) on a priority basis, the priority order of a transfer packet is made higher than that of a transmit packet so that the transfer packet is transferred to the Ethernet 820a or 820b in preference to the transmit packet. This prevents a transfer buffer means from overflowing. |

The channel decoding that follows makes the hard decisions about the transmitted symbols. Increased data rate is achieved by, effectively, splitting the incoming data rate into multiple channels, and each channel is transmitted over its own terminal. |

Network switch port aggregation
A network switch configures a static forwarding to a packet processor by suppressing packet switching and forwards all traffic received on a group of ports a trunk port for aggregation. A trunk header is overloaded with message classification information for use at the downstream packet processor. Routing logic retrieves the packet classification information and stores the information in control fields that are ignored due to the static forwarding and local switching disablement. The static forwarding forwards the packet, with the appended classification information, to a packet processor via the aggregation port. Packet classification information is indicative of the type of the message traffic and is performed upon packet arrival at the switching device. The packet processor reads the classification information from the overloaded control fields, rather then expending processing resources to determine the classification, and sends the message packet on an ingress port to a switching fabric for further transport. |

VLAN support of differentiated services
The two types of virtual local area networks (VLANs) may be defined: p-bits-Inferred-scheduling class VLAN (p-VLAN); and VLAN-ID-Only-Inferred-scheduling class VLANs (v-VLAN). As such, upon receipt of an Ethernet frame, the type of VLAN associated with the Ethernet frame may be determined. The type of VLAN provides the receiving node with an indication of a method of determining a scheduling class. A p-VLAN supports multiple scheduling classes. For a p-VLAN, the scheduling class and drop precedence for the received Ethernet frame may be determined based on a “service map” that describes the relationship between the p-bits and forwarding treatment. A v-VLAN supports a single scheduling class. As such, the scheduling class for a received Ethernet frame may be determined based on the VLAN-ID of the received Ethernet frame. The described VLAN QoS information may be configured or signaled across the network. Advantageously, the methods may be applied in connectionless, connection-oriented and path-oriented Ethernet networks. |

Acknowledge mode polling with immediate status report timing
A wireless network avoids delays in receiving status reports by having transmitters make sure that any outstanding Hybrid Automatic Repeat-reQuest (HARQ) processes in progress are all finished before sending the polling request. Thus, the receiver can respond to any polling request of the transmitter immediately without delay. Since the transmitter already ensures all HARQ processes are done, the receiver's status report will accurately reflect the latest information. The transmitter may send a poll anytime regardless of the HARQ processes if the most up-to-date polling is determined to be not as important (e.g., when the transmitter is trying to advance its transmitter window, in which case the exact Status info is not critical). The receiver may then react immediate upon receiving the poll. Thereby, detecting the loss of any piece of data within a data burst is expedited. |

Transmit power adaptation for wireless communication systems
When wireless systems are in communication with each other, transmit power levels can vary based on a distance between the communicating wireless systems. The transmit power levels may be varied by taking into consideration optimal values of performance indicators such as SNR.
