Given 20 bytes if IP header 20 bytes of TCP header 20 bytes

Given 20 bytes if IP header, 20 bytes of TCP header, 20 bytes of link-layer header. Suppose an application generates chunks of 20bytes of data every 20 millisecond. Each of these chunks of data gets encapsulated in TCP segment, IP datagram, and link layer frames. What percentage will be application data? What percentage will be header-overhead?

Solution

TCP 20 bytes

IP 20 bytes

link layer 20 bytes

66.67% is application date

33.33% is header overhead
