ABSTRACT:
The ATM transmitting apparatus for transmitting messages, such as frame relay packets, associated with a plurality of connections comprises ATM layer transmission equipment for receiving multiple messages, segmenting each received message into a plurality of smaller data units, such as 48 byte AAL SAR protocol data units, and multiplexing such data units into a single stream for transport over a physical interface. A scheduler receives messages from each of the connections and transfers the messages to the transmission equipment. The scheduler can dynamically set a transmission rate for any connection, and allocates each connection whose message is transferred to the transmission equipment a substantially maximal amount of bandwidth at any given time during the transmission of the message, to thereby minimize interleaving of data units from the various connections and reduce the average latency (per unit of message) in transmitting the messages across a network.
