PROJECTS:
> RF Engineering:-
Three layer interface wave propagation: Developed a three layer
interface wave propagation program which can calculate how much power
going through into the interface and how much power reflected back
from the interface .The whole coding was in MATLAB.
> Computer Internets and Protocols:-
Distance Vector routing Algorithm (protocol) design: The Algorithm was
implemented by programming in C -language based on given information for
given topology. The distance (cost) between router and update of router was
implemented by some command and instruction such as for loop, array. The
whole design was implemented, and verified using the theoretical result of
distance vector routing protocol.
Socket Programming Design:-
Client Server Model Design: Designed a client server model to communication
distributed application. Socket is created to be able to communicate on
both sides. Create a socket and stream for client and web server according
to their function in communication process. The whole design was
implemented on Java programming and verified real network.
. Echo Client Server Model Design: Designed an echo client server
model which was same as client server model but just one more
features added to it. Client get echo back look through the
server. Model was developed in Java programming and verified in
real network.
. Multi-Threaded Web server Design: Designed a socket programming
for multiple clients. Multiple clients can request
simultaneously to a single server and communication possible.
The whole design was implemented in Java Programming and tested
in real network.
Hands on LAB:-
Router configuration:-
. Basic router configuration with hostname, description, interfaces,
passwords (enable, enable secret, line console, line vty), Static
and dynamic routing.
. Sub netting and VLSM approaches on same network topologies.
. RIP (on given topology and summarization), EIGRP, OSPF and Link
state routing Protocol, DNS, DHCP, VLAN, VPN.
. Troubleshooting of given network topologies with wrong configuration
