Which feature can you implement to reserve bandwidth for VoIP calls across the call path?
A. PQ (Priority Queue)
B. CBWFQ
C. round robin
D. RSVP (Resource Reservation Protocol)
题库答案 D.RSVP
乾颐安堂讲解说选 A.PQ  老师说因为rsvp 一般不用在 voip
RSVP When implemented onall nodes in the path, RSVP guarantees bandwidth for the call along the entirepath for the entire duration of the call.

This is the only technique that achieves this level of accuracy.

PQ ensures that important traffic gets the fastest handling at each point where it isused. It was designed to give strict priority to important traffic.

看定义的话感觉想选 RSVP

大家怎么看?
