In allocating bandwidth using a Resilient Packet Ring (RPR) fairness mechanism in a node connected to an RPR network, when congestion occurs, an amount of traffic that the node has transmitted to a ring during one aging interval is recorded together with its own identifier in a fairness message as a fairness transmission rate to be advertised to its own upstream nodes and to be stored. The amount of traffic transmitted from the upstream node during the aging interval is measured and stored. When the congestion has been solved, an available bandwidth is calculated with reference to the fairness transmission rate which was recently advertised and the amount of traffic which has been transmitted from the upstream nodes, and the fairness transmission rate is calculated in order to fairly allocate the available bandwidth to the upstream nodes effectively so that the fairness transmission rate is transmitted to the upstream nodes. The upstream nodes transmit traffic in accordance with the fairness transmission rate.

A multi-hop wireless terminal having a user application section, a traffic control section and a wireless transmitting/receiving section, the traffic control section enqueuing a packet of a transmission flow from the user application section and a packet of a forward flow from the wireless transmitting/receiving section in queues different for each flow and performing traffic control, where the traffic control section includes a queue manager for sorting a packet of each input flow into a corresponding queue and enqueuing the packet, and a packet scheduler for dequeuing a packet from each queue and outputting the packet, and where the packet scheduler selects from the queues a queue from which a packet is to be dequeued and output, based on transmission information of each of the flows.

A system and method for generating a key list structure forming a queue of users' work flow requests in a queuing system such that many requests from a single user will not prevent processing of requests from other users in the queuing system. The key list structure comprises keys associated with users' work flow requests, each key indicating a priority level associated with a request, a user identification (User ID) associated with a requestor, and, an assigned user priority value (UPV). The method assigns UPVs to user requests in a manner such that user request entries become interleaved in the key list structure to prevent a single user from dominating the request processing.

A sending transmission control protocol (TCP) host is used in a first network node (106) to transmit TCP flows over a network segment to a receiving TCP host in a second network node (104). The sending TCP host comprises a TCP convergence module for aggregating all TCP flows through the network segment between the first network node (106) and the second network node (104) into an aggregate TCP flow (112). The receiving TCP host comprises a TCP convergence module for disaggregating the TCP flows from the aggregate TCP flow (112).

Provided is a method of calculating a fairness index that is a criterion indicating fairness of resource allocation between coexistence managers in a coexistence management system, the method including: calculating a normalized resource allocation amount by normalizing an amount of resources allocated to a corresponding coexistence manager to an amount of resources required by the corresponding coexistence manager with respect to each of the coexistence managers; and calculating the fairness index using the normalized resource allocation amounts calculated with respect to the respective coexistence managers.

A system includes a plurality of computers interconnected by a network including one or more switching nodes. The computers transfer messages over virtual circuits established thereamong. A computer, as a source computer for one or more virtual circuit(s), schedules transmission of messages on a round-robin basis as among the virtual circuits for which it is source computer. Each switching node which forms part of a path for respective virtual circuits also forwards messages for virtual circuits in a round-robin manner, and, a computer, as a destination computer for one or more virtual circuit(s), schedules processing of received messages in a round-robin manner. Round-robin transmission, forwarding and processing at the destination provides a degree of fairness in message transmission as among the virtual circuits established over the network. In addition, messages are transmitted in one or more cells, with the round-robin transmission being on a cell basis, so as to reduce delays which may occur for short messages if a long messages were transmitted in full for one virtual circuit before beginning transmission of a short message for another virtual circuit. For each virtual circuit, the destination computer and each switching node along the path for the virtual circuit can generate a virtual circuit flow control message for transmission to the source computer to temporarily limit transmission over the virtual circuit if the amount of resources being taken up by messages for the virtual circuit exceeds predetermined thresholds, further providing fairness as among the virtual circuits. In addition, each switching node or computer can generate link flow control messages for transmission to neighboring devices in the network to temporarily limit transmission thereto if the amount of resources taken up by all virtual circuits exceeds predetermined thresholds, so as to reduce the likelihood of message loss.

Provided are an apparatus and method for ensuring fairness of user datagram protocol (UDP) data transmission in an Ethernet environment. Transmission control protocol (TCP) transmission rate calculator calculates a current TCP transmission rate based on amount of a TCP data stream transmitted in real time from a transmission apparatus and received by a reception apparatus. TCP transmission rate calculator calculates the optimum transmission rate on the basis of the received amount of a TCP data stream transmitted to the reception apparatus before UDP data transmission of the transmission apparatus is started. When UDP data is transmitted from a transmission apparatus to a reception apparatus, a TCP data stream for determining fairness is transmitted together, so that the apparatus and method can be simplified by adding only the TCP stream without an additional module for estimating a queuing delay time on the basis of a round-trip time (RTT) and so on.

The fairness of radio communication between a donor base station and terminal devices is maintained. A relay apparatus 20 for relaying radio communication between one or more terminal devices 10 and a donor base station 30, wherein when the relay apparatus 20 receives a cell restriction instruction from the donor base station 30 to restrict a quantity of terminals capable of existing in a service area of a cell formed by the donor base station 30, the relay apparatus 20 executes processing for avoiding cell restriction operation on itself and transfers the cell restriction instruction received from the donor base station 30 to the terminal devices 10 existing in a service area of a cell formed by the relay apparatus itself.

The fairness of communication traffic guaranteed within an RPR ring is guaranteed also at a ring interconnection. Transmit weight information used for fairness control is extracted from RPR control information in an arrival packet. In addition to this transmit weight information, a source address, a service class, a fairness bit, and a ring transmit direction are also extracted. If the packet has a fairness bit of “0,” the packet is temporarily stored in an output queue by service class. If the packet has a fairness bit of “1,” the packet is weighted by source and ring transmit direction, based on the transmit weight information, and is temporarily stored in an output queue by source and ring transmit direction. Reading of packets from the output queue by service class is performed prior to reading of packets from the output queue by source and ring transmit direction.
