摘要： An optical wavelength division node includes an optical splitter, a plurality of optical circulators, and a colorless light source module. The optical splitter receives and splits a downstream signal light source into a first-path and a second-path signal light source. The optical circulator in a first-order position receives and transmits the first-path signal light source to an optical network unit in a first-order position, and receives a return signal and passes it to a next optical circulator, and finally the optical circulator in a last-order position receives the return signal and transmits it. The colorless light source module receives the second-path signal light source and the return signal transmitted by the optical circulator in a last-order position, and uses the second-path signal light source to modulate the return signal to generate an upstream signal light source to be transmitted to the optical line terminal by the optical splitter.

摘要： Disclosed is an apparatus and method for medium access control (MAC) in an optical packet-switched network. The MAC apparatus may comprise a bandwidth allocation module and an MAC processor. The bandwidth allocation module determines a data transmission limit based on a probabilistic quota plus credit mechanism for each node of the network, dynamically informs all downstream nodes of unused quota and allows the downstream nodes to use remaining bandwidths of the upstream node. Through a control message carried by a control channel, the MAC processor determines uploading, downloading and data erasing for a plurality of data channels, and updates the corresponding contents in the control message.

摘要： In a multiple access control system with intelligent bandwidth allocation for wireless ATM networks, an intelligent bandwidth allocator is provided for statically allocating reservation type bandwidth and dynamically allocating contention type bandwidth to the mobile terminal. A traffic estimator/predicator is provided for predicting the CNF value of a subsequent frame by the CNF value of at least one frame, and determining the number of the SCR slots and ABR slots to be allocated. A multiple access controller is used for providing the reservation type bandwidth with a multiple access function in a reservation access manner, and providing the contention type bandwidth with a multiple access function in a contention access manner.

摘要： The inventive system mainly includes a synchronization marker at a transmitting site and a synchronization forcer at a receiving site connecting to each other via computer networks. The synchronization marker performs the sequential mark marking of frames per every marking interval. The synchronization forcer regulates the play time of the audio signals and their corresponding video signals according to their sequential marks. The inventive system can determine precisely about the minimum marking interval yielding a bounded skew requirement. Consequently, the invention satisfies any given skew requirement under various buffer size and traffic arrivals while imposing minimal overhead.
