Performance analysis of per-VC queueing
Sylvain Archambault, Jie Yan · 2002
Per-virtual connection (VC) queueing allows an ATM switch to schedule cells to be transmitted on a link based on their VC. This alternative to the traditional first-in-first-out (FIFO) queueing is implemented by some switch manufacturers. This paper assesses the merits of per-VC queueing with regard to capacity, traffic shaping, and interworking with traffic management mechanisms such as connection admission control (CAC) and use of queue thresholds. The paper also discusses the conditions which favor the use of per-VC queueing.
