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： A medium access control (MAC) device and method for optical packet-switched metro wavelength division multiplexing (WDM) slotted-ring networks are used for providing quality of service (QoS) guarantees for isochronous traffic. The device includes a MAC processor and a distributed call admission control (CAC) module. The CAC module in each node of an optical packet-switched network is designed in a distributed manner, and flexibly allocates a reserved bandwidth to an isochronous traffic by a mean-rate-reservation method, controls a quota of the isochronous traffic below a quota ratio rH, resolves output contention by recording node locations forming a connection, and establishes a connection for each isochronous traffic. The MAC processor establishes a connection in the reserved bandwidth for each isochronous traffic between the nodes according to control information carried in a control channel, controls uploading, unloading, and erasing of a plurality of data channels, and updates corresponding contents in the control information.
