    摘要： The present invention provides a system and method for slot deflection routing of optical data packets. The method of the present invention includes the steps of establishing a schedule pattern that includes a plurality of time slots. The schedule pattern includes at least one time slot in which an ingress edge unit can communicate with a destination egress edge unit, at least one time slot in which the ingress edge unit can communicate with a intermediate edge unit, and at least one time slot in which the intermediate edge unit can communicate with the destination egress edge unit. The present invention also includes receiving a data packet at the ingress edge unit and determining if the schedule pattern allocates sufficient bandwidth to send the data packet from the ingress edge unit to the destination egress edge unit without deflecting the data packet through an intermediate edge unit. If enough bandwidth has been allocated, the data packet can be sent to the destination edge unit from the ingress edge unit without deflection. Alternatively, if enough bandwidth has not been allocated, the data packet can be deflected to an intermediate edge unit prior to being communicated to the destination egress edge unit.

    摘要： In a packet transfer method, a packet to be transferred to a destination access network is generated and transmitted to a transmission-source packet transfer apparatus connected to the transmission-source access network. The packet is converted into a superpacket having a length n times (n is an integer of 2 or more) larger than a fixed-length cell as a switching unit of a relay apparatus arranged on a network serving as a backbone, and sent to the network. The superpacket is relayed using the relay apparatus and transferred to a destination packet transfer apparatus connected to the destination access network. The packet generated by the transmission-source access network is reassembled on the basis of the superpacket transferred from the network, and sent to the destination access network. A packet transfer apparatus and packet communication system are also disclosed.

    摘要： An improvement of an ATM transmission system between a mobileservices switching center and a base station in a mobile communication system. A delay time for generating/sending out a cell is minimized to ensure the information quality required for real time transmission. When the transmission interval of a call type a is T, call types b and c whose periods are twice and four time that of the call type a should be transmitted at intervals twice and four times that of the call type a. A transmitted frame assembler/disassembler 104 in the base station prepares transmitted frames 201 each including the cell slots 201-1, 201-2 and 201-3 for transferring the respective call types, and schedules such that the transmitted frames are sent out to a channel 112 at the interval T, thereby enabling the transmission to be carried out without delay.

    摘要： At each network node, a packet classification unit makes a judgement to transfer only a packet necessary to be processed by software to a packet processing program processor and transfer other packets directly to a routing processor. Processing history information indicating the process history executed at each network node on a network route is transferred to the other network nodes so that other network nodes can store the processing history information in respective processing history repository table. Each node refers to this table and further transfers only the packet necessary to be processed by software to the packet processing processor.

    摘要： A method and apparatus are provided for processing data transmissions across data communications networks including ATM networks, for example, to support arbitrary user action on transmit completes. Sequential transport stream packets are obtained. A predetermined field of each transport stream packet is interrogated to identify a DMA on transmit complete. The transmission of a last cell in each transport stream packet is identified. Then responsive to identifying the DMA on transmit complete, an address for a DMA descriptor is fetched from the transport stream packet. The DMA descriptor is enqueued to a DMA engine to execute the DMA descriptor.
