Method of managing circular buffers in dynamic bandwidth emulation services |
摘要 |
In a method of managing buffers in a SAR (Segmentation and Reassembly) device operating in DBCES (Dynamic Bandwidth Circuit Emulation Service) mode, first an active channel buffer limit is determined. This is dependent on the number of active channels in the virtual circuit. Next, the amount of buffering for each active channel is set equal to the CDV (Cell Delay Variation) plus the active channel buffer limit. This prevents underruns over overruns from occurring when the number of active channels suddenly changes. |
