In this article we will look at an introduction to Linux. You will learn what is Linux, various features of Linux and what are the reasons for learning Linux. What is Linux? Linux is a open-source and free operating system (unlike Microsoft Windows and Mac). It serves as a foundation for various distributions […]
Configuring a Router using CLI in Cisco Packet TracerThis article provides links to all DCCN lab programs. Many of the lab programs are provided with textual links as well as video links to support a wide range of audience. Software required to conduct/perform DCCN lab experiments are Cisco Packet Tracer (CPT), Java and Network […]
Aim To implement TCP congestion control algorithm. S/W required NS2, Xgraph Background information Congestion is an important factor in packet switched network. It refers to the state of a network where the message traffic becomes so heavy that the network response time slows down leading to the failure of the packets. It leads […]
Aim To implement Link State Routing algorithm. S/W required NS2 Background information The Link State Routing Algorithm is an interior protocol used by every router to share information or knowledge about the rest of the routers on the network. The link state routing algorithm is distributed by which every router computes its routing […]
Aim To implement Distance Vector Routing algorithm. S/W required NS2 Background information Distant vector routing protocol also called as Bellman-Ford algorithm or Ford Fulkerson algorithm used to find the shortest route from one node to another node in the network. A distance-vector protocol calculates the distance and direction of the vector of the […]
Aim To implement flow control protocols like Sliding Window, Go Back N, and Selective Repeat protocols. S/W required NS2 Background information Sliding window protocol The working of the sliding window protocol can be divided into two steps sender steps, and the receiver steps and also some important values are needed in a network […]
Aim To implement stop-and-wait protocol. S/W required NS2 Background information Flow control Flow control is a technique that allows two stations working at different speeds to communicate with each other. It is a set of measures taken to regulate the amount of data that a sender sends so that a fast sender does […]
Aim To implement High-Level Data Link Control (HDLC) protocol. S/W required Cisco Packet Tracer Theory HDLC (High-Level Data Link Control) is a bit-oriented protocol that is used for communication over the point-to-point and multipoint links. This protocol implements the mechanism of ARQ (Automatic Repeat Request). With the help of the HDLC protocol, full-duplex […]
Aim To write a socket program for implementing ping command in Java. S/W required Java Background information Client-server communication model One of the widely used way of communication across the Internet is the client-server communication. In this communication model, there is a system called server which always listens for connections from clients. Once […]
Aim To implement client-server communication using socket programming. S/W required Java Background information Client-Server communication model One of the widely used way of communication across the Internet is the client-server communication. In this communication model, there is a system called server which always listens for connections from clients. Once a connection has been […]
