INTERNETWORKING WITH TCP/IP
Answer to Question 1:
Link Layer Frame – it is used for encapsulating the network layer datagram
Network Layer Datagram – It consists of the source and destination IP address written in
the header and similar to the packets but contain a small piece of data with the use of connection
less protocol.
An Application Layer Message – The message is denoted for the unit of information
whose entity of source and destination exists in the application layer (Tan, 2018). The
application layer manages the user interface and include network application for example email,
FTP, Telnet. The message has header and data.
Answer to Question 2:
Reliable data transfer using UDP Protocol
Yes, it is possible for an application to enjoy reliable data transfer even if the application
is running on UDP.
The reliability can be added at the application level with the use of different protocols such
as:
 Connection handling (maintain a track on the connection)
 Sequencing (rely on the frame orders)
 Acknowledgements (Making sure that all the frames are received)
 Flow control (throttling the data flow)
Another method that can be used for increasing the reliability is to send all the packets as
normal UDP packet and at the receiver end the packets are indexed (Pavarangkoon et al., 2017).

INTERNETWORKING WITH TCP/IP
After sending the packets a list of packet index is sent that are not received and thus it can
improve the reliability of UDP.
Answer to Question 3:
Details of the router connected with the three subnets are given below:
Subnet 1 – No. of interfaces 60
Subnet 2 – No. of interfaces 90
Subnet 3 – No. of interfaces 12
The following is the network address calculated from the major address 223.1.17.0/24
with the details of the steps following for getting the answer:
254 number of hosts are available for the subnet /24 (255.255.255.0). The major network
is subdivided into subnet address for meeting the constraint and the details of each of the subnet
is tabulated below (Kralicek, 2016).
