18CS54 - network programming and security
============================================================
Q1: Write a networking program consisting of a client and
server components. The client must request for a file by
providing a file name, and the server must respond with the
contents of the file or an appropriate error message.
Modify the client to accept the filname via a command line
argument.

Q2: Write a program to illustrate the function of
Distance-Vector routing using Bellman-Ford algorithm. Handle
the situation where negative edges are present.

Q3: Write a program to showcase
a) Checksum - error detection
b) Hamming code - error detection and correction

------------------------------------------------------------
Q6: Write a networking program to demonstrate the following:
a) Concurrent TCP server
b) Iterative TCP server
c) Connectionless UDP server

b) https://u.peppe.rs/VA.png
c) https://u.peppe.rs/ei.png
------------------------------------------------------------
Q7: Write a networking program that recieves a shell command
from a client and returns the output of the command to the
client.

============================================================
PART B
============================================================
Q1: Setup an IEEE 802.3 network with
a) hub
b) switch
c) hierarchy of switch
Apply the FTP, Telnet applications between nodes. Vary
the number of nodes. Vary the bandwidth, queue size and
observe the packet drop probability.

------------------------------------------------------------
Q2. Setup a wireless sensor networks with atleast two device
co-coordinators and nodes. Provide Constant Bit Rate (CBR),
Variable Bit Rate (VBR) application between several nodes.
Increase the number of co-coordinators and nodes in the same
area and observe the performance at physical and MAC layers.
A2: https://u.peppe.rs/qualnet/exp3
------------------------------------------------------------
Q3. Setup an IEEE 802.11 network with at least two access
points. Apply the CBR, VBR applications between devices
belonging to same access points and different access points.
Provide roaming of any device. Vary the number of access
points and devices. Find out the delay in MAC layer, packet
drop probability.
