摘要： A determining unit determines an allowable rate of data input permitted at a local node. A generating unit generates, when the allowable rate determined by the determining unit is equal to or greater than a target rate of the local node, extended control information including satisfaction information indicating that the target rate is achieved. A transmitting unit transmits the extended control information generated by the generating unit to an upstream node.

摘要： A learning-target packet to be used for a path learning is selected from among a plurality of packets queued by a relay apparatus. A relationship between a transmission-source address and a first-arrival port for the selected learning-target packet is registered as learning information. A packet corresponding to the registered learning information is transferred to the first-arrival port pertaining to the learning information, and a packet that does not correspond to the learning information is transferred to all ports to which the packet is to be transferred.

摘要： The present invention relates to a buffer control apparatus and method. In a buffer control apparatus for controlling storage process for a common buffer which is commonly used for a plurality of routes and temporarily stores data received from the routes, the buffer control apparatus comprises a route discriminating section for identifying the routes of the received data; a storage section for storing at least information concerning a storing position for the received data within the common buffer for each of the routes; and a control section for performing a control operation for virtually storing, route by route, the received data into the common buffer according to a result of route identification in the route discriminating section and the information concerning the storing position in the storage section, whereby the storage control in the common buffer is performed such that the common buffer can be virtually used as discrete buffers, in order to secure minimum band for each of the routes without increasing the capacity of the buffer and complicating the readout control for the buffer.

摘要： When a packet arrives, a packet processing unit judges whether coincident information is present in an identity information table. When no coincident information is present, the packet processing unit registers the entire packet, a hash value of the entire packet, a predetermined part of the packet, or a hash value of the predetermined part of the packet. In addition, the packet processing unit performs identity judgment for the packet based on the information registered in the identity information table.

摘要： The present invention relates to the rate control system of a TCP layer in communications conducted between terminals 1 and 3 via a base station 2 using a wireless link. An object of the present invention is to avoid the fruitless reduction of throughput in communications conducted via a wireless link. If the discard of a packet transmitted from the base station 2 to the terminal 3 via a wireless link is detected when the packet is transmitted from the terminal 1 to the terminal 3, the base station or terminal 3 is provided with means for notifying the terminal 1 of a wireless packet discard using a TCP layer. The terminal 1 is configured in such a way that if the wireless packet discard notification is received, a TCP layer control unit 10 does not exercise slow-start control at the time of re-transmission and re-transmits the discarded packet at a rate adopted before the reception of the notification.

摘要： A cell transmitted from a transmitting terminal is multicast to a plurality of receiving terminals. The plurality of receiving terminals respectively transmit B-RM cells to the transmitting terminal. Each of the B-RM cells is assigned an ER value. An ER value calculating unit calculates an average value of the ER values which are respectively assigned to the B-RM cells from the plurality of receiving terminals. A B-RM cell processing unit transfers to the transmitting terminal a B-RM cell to which the ER value calculated by the ER value calculating unit is assigned. The transmitting terminal controls the transmission rate of a multicast communication with the plurality of receiving terminals according to the ER value assigned to the received B-RM cell.

摘要： A communications system whose bandwidth resources can be used more efficiently by reserving them on an individual path basis. Upon receipt of a bandwidth reservation message, a path setup initiator examines the message and thereby recognizes that the local station device is the egress node of a specified logical network segment. It then consults a topology database to retrieve hop counts of the source station device, which reveals, for example, that a first ringlet has a smaller hop count than a second ringlet. The path setup initiator sends a working path setup message to the ingress network device over the first ringlet, as well as a protection path setup message to the same ingress device over the second ringlet. Upon receipt of those messages, a bandwidth reservation unit reserves a working path bandwidth on the second ringlet, as well as a protection path bandwidth on the first ringlet.
