1
In a token ring network the transmission speed is $10^7$ bps and the propagation speed is $200 , m/\mu s$.
The 1-bit delay in this network is equivalent to ______.
Solution
Transmission speed
$10^7$ bits/sec
Time for 1 bit
$\frac{1}{10^7}$ sec
Convert to microseconds
$\frac{1}{10^7} \times 10^6 = 0.1 , \mu s$
Propagation speed
$200 , m/\mu s$
Distance traveled in $0.1 , \mu s$
$200 \times 0.1 = 20 , m$
