ANSWER: B

CRC performance

  •  All burst errors of length equal to the polynomial’s degree are detected

  •  All burst errors affecting an odd number of bits are detected

  •  Burst errors of length greater than the degree of polynomials are detected with high probability

  •  32-bit CRC used in Ethernet, Token Ring

Station$A$ uses $32$ byte packets to transmit messages to Station $B$ using a sliding window protocol. The round trip delay between $A$ and $B$ is $80$ $ms$ and the bottleneck bandwidth on the path between $A$ and $B$ is $128$ $kbps$. What is the optimal window size that $A$ should use? $20$ $40$ $160$ $320$
