A TCP/IP protocol suite is the collection of communication protocols needed to communicate over Ethernet. The three most important components of the TCP/IP protocol suite are IP, TCP, and UDP. IP - IP is the Internet protocol. It is responsible for moving a packet from point A to point B. IP knows nothing about TCP, CIP, or Ethernet/IP. It simply moves the data packets provided to it by TCP, UDP, and other protocols in a TCP/IP suite. Now suppose an application layer entity wants to send an L-byte message to its peer process, using an existing TCP connection. The TCP segment consists of the message plus 20 bytes of header. The segment is encapsulated into an IP packet that has an additional 20 bytes of header. The IP packet in turn goes inside an Ethernet frame that has 18 bytes of header and trailer. What percentage of the transmitted bits in the physical layer correspond to message information, if L = 100 bytes, 500 bytes, 1000 bytes?

<Q95> A TCP/IP protocol suite is the collection of communication protocols needed
to communicate over Ethernet. The three most important components of the TCP/IP
protocol suite are IP, TCP, and UDP.
IP - IP is the Internet protocol. It is responsible for moving a packet from point A to
point B. IP knows nothing about TCP, CIP, or Ethernet/IP. It simply moves the data
packets provided to it by TCP, UDP, and other protocols in a TCP/IP suite.
Now suppose an application layer entity wants to send an L-byte message to its peer
process, using an existing TCP connection. The TCP segment consists of the message
plus 20 bytes of header. The segment is encapsulated into an IP packet that has an
additional 20 bytes of header. The IP packet in turn goes inside an Ethernet frame that
has 18 bytes of header and trailer. What percentage of the transmitted bits in the
physical layer correspond to message information, if L= 100 bytes, 500 bytes, 1000
bytes?
