You are required to simulate the behavior of a packet switching network inside the laboratory. The creation of a network will require using the packet and link editors; defining the collected statistics; and learning new Kernel procedures. Some other benefits that will be derived from the lab include learning the principles of model design; becoming familiar with the node and process models; learning how the node and process models function within a network model; carry out parametric studies of various statistics. The performance of a simple packet switching network is measured by the end-to-end delay experienced by traffic on ...

1. Impact of network congestion on productivity Network congestion occurs when a link or a node carries too much data that its normal capacity thus making its efficiency to be reduced. Some of the effects of network congestion include: queuing delays, blocking of new connections and packet losses in the network. (Floyd & Fall, 2009) Network congestion leads to an overall reduction in the network’s throughput. Network congestion usually affects the productivity of the network in the following ways: i. Delay – whenever there is congestion in the network, users will have to wait for longer periods of time ...

Introduction

A network switch is a small hardware device that is used to connect two or multiple computers within a local area network (LAN). This enables the paring of the computers hence sharing of information is facilitated. The networking switches normally operate at a layer two that is data link layer of the Open Systems Interconnection model (OSI). Network hubs are very similar to network switches but after close scrutiny, a network switch can inspect data packages received, can determine the final destination while sourcing the original source of the data. They deliver the message to the devices connected to the network hence ...
