Methods for aggregating cells transported in a bonded group

摘要

Transporting an asynchronous transfer mode (ATM) stream through a bonding group involves properly splitting the stream into sub-streams to fit into individual member bearer's bandwidth at the transmit end, and properly merging the sub-streams to reconstruct the stream at the receive end. At the receive end, the cells can be put together in the proper sequence in a process of cell aggregation based on attached sequence numbers. Once the stream is re-constructed, the attached sequence numbers are replaced by the original field contents of the ATM headers. Methods of cell aggregation are described that assist the bonding scheme in working efficiently.
