    摘要: Information (cell) that is to be transmitted at least partially via a packet-oriented communication network, e.g. Ethernet (IEEE 802.3) or via a cell-oriented communication network is inserted as useful information into a useful data field of at least one data packet of the communication network, which contains target and useful data respectively, or into a time slot of the time-slot oriented communication network. According to the invention, additional routing information for the transmission is assigned to the information prior to insertion into the data packet or time slot, whereby the information that has been sent with the data packet or time slot to a destination in the packet-or cell-oriented communication network is transmitted in accordance with the respective assigned routing information. The invention permits information cell, cell that is to be transmitted via different connections to be transmitted cost-effectively and transparently via a packet-oriented communication network.

    摘要: A method of assembling a plurality of frames including cell/packet-formatted data according to a predetermined frame format for transmission in a communication signal in a wireless or satellite environment. The method begins by assembling a data payload for each frame having a first variable size, including at least one of a partial data cell/packet and a complete data cell/packet. Then, for each frame a block code having a second variable size is generated for use in error correction. Each frame is provided with a frame header which defines aspects of said frame. Finally, the data payload, the block code and the format header are combined to form a frame corresponding to the plurality of frames, the format header defining a first portion of the frame, the data payload defining a second portion of the frame and the block code defining a third portion of the frame.

    摘要: A packet scheduler controls dispatch of packets containing constant bit rate (CBR) or real time variable bit rate (rt-VBR) at an ingress operation of multiplexing the packets into payloads of an asynchronous transfer mode (ATM) bearer virtual circuit connection. Packets can be queued in one of a number of queues according to priority. The scheduler controls assembly of common part sublayer payload data units (CPS-PDU) comprising any unused octets from a previous packet partially dispatched, and whole packets in order of priority. If a holdover timer period expires before a common part sublayer payload data unit is completed, the payload of that data unit is packed with null data; and dispatched. The packet dispatch is controlled so as to match the traffic characteristics of an underlying bearer channel

    摘要: A scheme for implementing GFR service in an ATM environment, e.g., an access node's ATM switch fabric. Regulation of a GFR flow is throttled between two modes, a guaranteed rate mode and a non-guaranteed rate mode, depending upon timestamps computed by applicable traffic policer/shaper algorithms. A scheduler is operably coupled to a policing block for scheduling cells from a guaranteed flow queue for transport via the ATM fabric at a guaranteed rate upon determining the onset of a guaranteed service frame. The scheduler switches to non-guaranteed rate mode for scheduling cells from the flow queue at a non-guaranteed rate when a timestamp (TSNGF) for transmission at the non-guaranteed rate is earlier than a timestamp (TSGF) for transmission of a next guaranteed service frame at the guaranteed rate.

    摘要: A system for encapsulating ATM cells into larger data packets to be transmitted through a broadband communications system includes an ATM cell receiver (410), a data packet formatter (430), a buffer (434), and a data packet formatter controller (438). The ATM cell receiver (410) receives ATM cells and sends them to the buffer (434) which is included within the data packet formatter (430). Data packet formatter controller (438) controls the insertion of ATM cells into the buffer (434), and also optionally compresses the ATM cells to increase the apparent bandwidth of the system.
