摘要：This paper showed an analysis and comparison between new buffer design with both concept buffers in the PQ algorithm and SPBA algorithm. In the PQ algorithm, there are four buffering packet are low, normal, medium and high. The buffering packet in PQ algorithm is greedy. However, fourth the buffering is not optimal used. It is caused by PQ algorithm is based on the priority, whereas this buffering just always serviced is the highest priority. While under priority are rarely or never serviced will cause other buffering rarely used. While SPBA algorithm is architecture easiest, and it does not need any resource reservation or threshold dropping, but only makes use of priority scheduling. SPBA algorithm, where incoming packets are placed into the two priority traffic classes is the high class and low class. On the SPBA algorithm is there are not available reservation sources to save the remaining packets when the explosion (burst) traffic occurred, that could result in packet drop and packet loss. Then, with the efficiency of PQ buffering algorithm, can provide greater impact to reduce delays. In the new buffering algorithm, simplify four buffering into three packets (High, Medium and Low) is proposed. In the analysis and comparison new buffering algorithm could be known problems and weaknesses of both algorithms.
