token is 64 bytes long (the 10-Mbps Ethernet minimum packet size), what is the average wait to receive the token on an idle netw

ikadub [295]

Given that,

Token is 64 bytes long

The average number of stations that the token must pass = 20

We need to calculate the transmission delay for token

Using formula of transmission delay

$Transmission\ delay=\dfrac{token\ size}{minimum\ size}$

Put the value into the formula

$Transmission\ delay=\dfrac{64\ bytes}{10\ Mbps}$

$Transmission\ delay=\dfrac{64\times8}{10\times10^6}$

$Transmission\ delay=0.0000512\ sec$

$Transmission\ delay=5.12\times10^{-5}\ sec$

We need to calculate the average wait to receive token on an idle network with 40 stations

Using formula of average wait

$\text{average wait to receive token}=\text{average number of stations that the token must pass}\times transmission\ delay$

Put the value into the formula

$\text{average wait to receive token}=20\times5.12\times10^{-5}$

$\text{average wait to receive token}= 0.001024\ sec$

$\text{average wait to receive token}= 1.024\ ms$

Hence, The average wait to receive token on an idle network with 40 stations is 1.024 ms.
