This essay has been submitted by a student. This is not an example of the work written by our professional essay writers.
Final year students are supposed to present their individual projects, throughout the world a group of student's different kind of doing projects on a variety of applications using number of different technology. Networking really works out and changes the whole scenario and gives biggest platform of information worldwide that connect the people very smoothly, now today is the epoch of networking, development and designing.
This project basically finds out the measurement of performance of an existing enterprise LAN network in an organization, as a result I come to know various problems and afterwards propose solution must be found to resolve the existing problems, by that the enterprise network LAN performance can get better, furthermore, it can hold most up-to-date multimedia application traffic effortlessly, therefore, in future the company be capable to vigorous and make bigger its economic balance.
QoS plays an important role for an effective and constant process in broadband networks.
The aim of this project is to investigate the QOS in IP over ATM and IP over MPLS networks, and after through investigation suggest the suitable network for the future real time broadband networks.
This project will mainly discuss and focus on finding out new methods of improving our all performance of the network with the help of journals and different citations that are applicable.
Research conducted by evaluating the literatures, books, articles and journals to come across that how the mixture of traffic should deliver on enterprise LAN network.
Accomplish investigation by getting and comparing online articles and further relevant different sources of information includes the OPNET manipulation, uses of conventional hierarchy that comprises of all layered function of the OSI model particularly layer 2 and layer 3. Other information to facilitate will be used include the following:
OPNET modeler books.
Internet journals and Electronic citations.
b) Experimental Objectives
At first, examine the performance and effect of the existing system.
Examine the end-to-end delay, utilization in prearranged system.
Secondly, suggest a new fresh system with the implementation of QoS policy schemes (FIFO and WFQ) to boost the performance of the network as well as aim to get rid of the mistakes.
Thirdly, use of VoIP traffic on the evocative system, to accurately measure the traffic load and efficient utilization of bandwidth as a result, company can formulate decision whether to go for promote the system or make use of the existing one.
My primary focus in the current is to comprehensively measuring the end-to-end delay moreover; reduce by implementing QoS in the existing system.
To start work on this project the first step is to find out the help topics of OPNET simulator to learn how to build the environmental network, afterwards how to configuring profile, application description, placement of the accurate devices, limitation setting and manage them.
Determine the error packet, overcrowding, end-to-end delay, scalability and dependability.
Second step is to evaluate the necessary parameters for the simulation of desire scenario. If there is a number of errors become known, recognize and get rid of them to fix the errors.
Eventually, prepare a clear and wide-ranging report on the research area and OPNET as a whole.
3) How the objectives will be achieved
This project describes the basic feature of MPLS over ATM features, IP over ATM features and multimedia application traffics with special value of service (QoS) necessities.
With the use of Imitation instrument, the MPLS over ATM feature given that ABR, CBR and VBR QoS support, and the IP over ATM feature given that an old UBR QoS feature for relocating data, voice and video traffics are modeled.
With the help of Imitation of the models under changeable offered loads, acquired imitation outcomes are explained.
Make a comparison between QOS in IP over ATM and IP over MPLS networks.
With the evaluation of the normal end to end-delay and delay variation graphs; not only does the MPLS over ATM technique endow with better outcomes for all the multimedia traffics.
Therefore to reduce the end-to-end-delays a most awful drawback of the IP over ATM features creating with the same and unreliable results for the data voice along with video application traffics for a smooth network.
b) Secondary Goals
Due to irregular and high end-to-end delay and delay different effects becomes the most important trouble in the consumption of IP over ATM and networks for in particular multimedia functions.
It is neither sufficient nor good enough to use the IP.
QoS supports, which is provided by the primary ATM network, MPLS over ATM technique grants a great deal of appropriate infrastructure for specifically multimedia traffic transferring as compared to the IP over ATM techniques.
MPLS over ATM has yielded not merely improved and minimum average end-delay and delay differences as compared to IP over ATM; however, it has distinguished the multimedia traffics according to their required QoS.
As a result, voice, video as well as data traffics experience diverse end-to-end average delay and delay variations due to fair and well-organized use of ATM backbone resources offered.
