基於ieee802 . 1p和802 . 1q的隊列機制，採用逐跳選擇式背壓流控機制和頭端阻塞保護機制消除擁塞，改善系統性能。 -
Caused by the strict fifo service rule, hol cell block is the very disadvantage of the input - queued atm switches. to solve the problem, two things should be considered, that is the selection of scheduling strategy " and the decision of switch structure
輸入排隊atm交換的最大問題是它的隊首（ hol ）阻塞，它是由於嚴格的fifo服務規則所引起的，在對該問題的解決上主要涉及兩個方面：調度策略的選擇和交換結構的確定。 -
In the optimization design of advanced router, since it exists hol blocking in iq program, and when the number of ports is large or the line rate is very high, the present memory cannot have so fast frequency in oq program, so cioq program is adopted now
在路由器的優化設計中，由於輸入端排隊方案存在隊首堵塞且輸出端排隊方案在主幹網上存在加速過高而現有的內存頻率跟不上的弊端，所以現在採用了組合輸入輸出端排隊方案。 -
Because of block in head of line ( hol ), input buffer strategy make the whole switch system performances declining drastically at heavy oflbred load, and some improvements of input buffer strategy are put forward to overcoming tlle head of line block. virtual output queues ( voq ) is chosen as input buffer strategy. dpa and ilqf ce1l scheduling algorithms for voq are silllulated
由於輸入緩存的隊頭阻塞使得高負載條件下輸入緩存策略的交換系統各方面性能急劇下降，由此提出了克服輸入緩存隊頭阻塞的改進方法，最後本文決定選用虛擬輸出隊列（ voq ）的輸入緩存策略，並且研究了與虛擬輸出隊列相對應的ilqf （最長隊列優先）和dpa （對角線優先）信元調度演算法，為交換系統的asic設計提供依據。
