Abstract
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.
