Abstract
A system schedules both CBR and non-CBR traffic on one or more virtual paths in accordance with associated aggregate peak cell rates by including in a stream of data cells strategically placed “CBR opportunity cells.” The CBR opportunity calls, which operate essentially as placeholders for the insertion of the CBR cells produced by a conventional AAL1 segmentation and reassembly processor (SAR), are included in the stream at locations that correspond to or exceed the fastest rate at which the associated CBR cells are generated. An add/drop multiplexer queues the CBR cells produced by the AAL1 SAR by virtual path, and replaces the respective CBR opportunity cells in the VBR stream with the queued CBR cells associated with the same virtual path.
