摘要： In the bandwidth-allocating method of the present invention for PON (: Passive Optical Network), a bandwidth is allocated from an optical line terminal to each optical network unit. The optical line terminal stores a bandwidth contract table for indicating a correspondence relationship between communication flow IDs and service quality parameters, each communication flow ID identifying each communication flow between the optical line terminal and each optical network unit. The bandwidth-allocating method includes a step of transmitting a service-quality request message including the communication flow IDs and the service quality parameters from each optical network unit to the optical line terminal, and a step of the optical line terminal's updating the bandwidth contract table based on the service quality parameters, and performing the bandwidth allocation to a communication flow specified by the corresponding communication flow ID based on the bandwidth contract table.

摘要： To more fully utilize the available bandwidth of a network link, network nodes in accordance with the present invention allow TDM data to be combined with packet data. A Packet/TDM cross connect switch, having both a TDM switch and a packet switch, is used in these embodiments. Data packets are transformed into TDM packet columns. The TDM packet columns are combined with standard TDM data columns in the payload of a TDM data frame. Data packets may be sorted based on a priority scheme, in which high priority data packets are given precedence over lower priority data. However, both high priority and low priority may be combined in a TDM packet column

摘要： An optical network, which includes edge and switching nodes, optically communicate information formatted into statistically multiplexed control and data bursts and/or metadata. Control bursts are transmitted prior to the data bursts to configure optical switches in selected switching nodes so that the data bursts do not require O-E-O conversion. Each edge node consists of an adaptive PBS medium-access layer (MAC) component in order to achieve the transmission throughput improvement. The adaptive PBS MAC component enables the PBS data burst size to adapt to the TCP flow, allowing the PBS data burst to be transmitted immediately for the TCP flow experiencing TCP slow start. It performs a “deep” packet inspection of control packets coming back to the data source from the destination PBS network edge node to detect packet losses.

摘要： There is disclosed an QoS-oriented burstification method supporting various grades of burstification delay guarantee. For the arrival packets, the packets are sequentially inserted in a sequence of windows on weight basis, thereby forming a queue. The window size together with the weight of each flow determines a maximum number of packets of each flow in a window. For the departure packets, there is generated a burst consisting of a plurality of packets from the head of the queue when either a total number of packets reaches a maximum burst size or a burst assembly timer expires.

摘要： A device (D) is dedicated to generating bursts of packets of data, in a network equipment (N) of a burst switching communication network. This device (D) comprises processor means (MT) adapted to generate, with a view to their transmission by the equipment (N), composite bursts assembled from packets extracted from at least two queues, including an initiator queue, associated with different classes of service and with a common packet destination, and defined in memory means (MY). To this end the processor means (MT) allocate to the different classes of service selected weights varying in a non-linear fashion as a function of associated priority levels. They then determine a linear combination of proportions of packets stored in the initiator queue and in at least one other queue associated with the same destination respectively weighted by the weights allocated to the classes of service of the packets, the result whereof preserves the priority level associated with the packets stored in said initiator queue. Finally, they assemble a composite burst to be transmitted with the packets of the linear combination.

摘要： In a wide-coverage network comprising electronic edge nodes interconnected by bufferless core nodes, where each edge node comprises a source node and a sink node, both sharing an edge-node controller and having means for data storage and managing data buffers, the transfer of bursts from source nodes to sink nodes via the core nodes requires precise time coordination to prevent contention at the bufferless core nodes. A core node preferably comprises a plurality of optical switches each of which may switch entire channels or individual bursts.Each source node has a time counter and each core node has at least one time counter. All time counters have the same period and time-coordination can be realized through an exchange of time-counter readings between each source node and its adjacent core nodes. The time-counter readings are carried in-band, alongside payload data bursts destined to sink nodes, and each must be timed to arrive at a corresponding core node during a designated time interval. The difficulty of securing time-coordination arises from two interdependent requirements: communicating a time-counter reading from a controller of a source node to a controller of a core node requires that the source node be time-locked to the core node, and time-locking a source node to a core node necessitates that a controller of the core node be able to receive a time-counter reading from the source-node controller during a designated interval of time. To initiate or restore time locking, a secondary mechanism is required for directing upstream signals received from source nodes toward said master controller. The present disclosure provides such mechanisms.
