The APRCA (Adaptive Proportional Rate Control Algorithm) and APRCA2 are explicit rate based congestion control algorithm which indicates congestion by the change of queue length. Some researchers have concluded they have better performance than EPRCA. But in this paper, we show that these protocols are unstable in some conditions.
自我調整比例控制演算法 (APRCA) 和 APRCA2 是基於顯式速率 (ER) 的擁塞控制演算法,它們通過檢測排隊長度的變化來確定是否擁塞,一些學者的工作表明它們具有比增強比例控制演算法 (EPRCA) 更好的性能,但在本文中,我們證明了這種演算法是不穩定的.在一些情況下,隊長會常常超過嚴重擁塞門限.
