Question

You are required to design a QoS architecture videoconferencing application. First you need to elaborate QoS requirement of your application and then you are required to provide the application design based on Integrated Services (IntServ) and Differentiated Services (DiffServ). The design must include how you can provide these services to your application over the local and core network devices (local routers, core networks (routers), and switches etc). After presenting the design, give your opinion on which QoS architecture will make it easier for your application to be implemented over network.

Answer 1

Solution:

As we know that the QoS stands for the Quality of Service.It basically refers to the a network that set of technologies that ensure the network to deliver the required results. The QoS also help to enhance the performance of the network in terms of latency,availability,error rate and the throughput.Ans we also know that the QoS supports prioritizing network traffic.That helps in the prioritizing the traffic in the network.The best thing is that the QoS also consider the specific router or server, etc.And with the help of this the network monitoring systems are deployed, that is the one of the part of the Qos and it ensure about the network that performing at the desired level. And we know that the QoS provides two types of services:

Integrated services .
Differentiated services.
We have already seen about this two services.

Now , coming to the how we can design a QoS architecture video conferencing application:To implement the QoS architecture video conferencing application ,firstly we have to take the proper analysis with that we can find out the proper requirement .On the basis of that we use the two services that are the Integrated services and the Differentiated services .We take the key features of the both the services and on the basis of that we implement in the architecture of the video conferencing application.

As we know that the QoS is the complex and the vast subject that require in the consideration of overall traffic requirements.To achieve the video quality in a video conference it is a complex task that involves in the addition to the network components,to examin and review the configuration and tuning at the endpoints.Some of the key points that we entails in the video quality are as follow:

End-point tuning.
Interoperability considerations.
Transport optimization
Some of the parameters on the video endpoints are as d\follows:

Frame rate.
Resolution.
Tagging.
So,we have to maintain all this aspects when we have to to design a QoS architecture videoconferencing application .We have to design the appropriate QoS policies, that basically ensure SLA is to met for each traffic class.

THANKS , i think this will give you a better intuition about your question.If yoou have any doubt feel free to ask in the comment section
