    摘要: In order to improve the efficiency of optical data transmission between network interfaces (NIC1-NIC6) over a shared transmission medium (OR), one or more traffic channels (λt) and at least one control channel (λc) are provided. All network interfaces (NIC1-NIC6) will be synchronized to an absolute time reference (PTR1, PTR2). Data to be transmitted are assembled in the network interfaces into chunks. These chunks are scheduled for transmission by determining the availability of a selected one of said traffic channels at a scheduled transmit time. The scheduled transmit time and the selected traffic channel are announced to the other network interfaces via the control channel. At the scheduled transmit time, the scheduled chunk is transmitted over the shared transmission medium on the selected traffic channel.

    摘要: The present invention provides a high capacity switching system for use in a transport network, which contains a number of input/output subsystems and a central interconnection means configurably interconnecting the input/output subsystems. The subsystems have input/output line modules for receiving and transmitting data signals to and from transmission lines of the network, one or more link modules connecting the subsystems to the interconnection means, and local switching means switching data signals in time and space domain between the input/output modules and the one or more link modules within one subsystems. The link modules are adapted to aggregate data signals from different input/output line modules of the same input/output subsystems and destined to input/output line modules of another one of said input/output subsystems into signal bursts and add a payload gap to each signal burst. The switching system further has a scheduler which configures the interconnection means during the payload gaps to switch the signal bursts to their destination subsystems.

    摘要: A method and related apparatus for transmitting an asynchronous transport signal over an optical fiber section of an Optical Transport Network is described. Higher order Optical Data Units (20) of an asynchronous transport signal to be transmitted will be encapsulated into outer transport frames (30) that offer a payload rate higher than a nominal bit rate of the asynchronous transport signal. An output optical signal, which contains the outer transport frames (30) with the encapsulated asynchronous transport signal, is generated at a locally generated clock rate (44) and transmitted over an optical fiber section. To encapsulate the asynchronous transport signal, its bit rate is adapted to the payload rate of the outer transport frames (30), which is derived from the locally generated clock (44) through a justification and stuffing process. This eliminates any frame phase or frequency transients occasionally appearing in the received asynchronous transport signal. The rate adapted transport signal is then synchronously mapped into the outer transport frames (30) at the rate of the locally generated clock (44).
