Data becomes the lifeline of our world today. Different business enterprises use data to improve efficiency and reduce cost.
Even in our daily lives, we are constantly connected with the network and streaming some data. But what if we don’t get it the way it is required? What if there are jitters, delay, and inconsistencies?
To Ensure a smooth data transfer, there is a process in the field of Networking called QoS. So, if you wonder ‘what is QoS?’, let’s discuss this in detail. QoS or Quality Of Service assigns priority to different essential data types and thus reduce data loss, lowers jitter and data latency.
QoS applies to real-time, resource-intensive data that has a short life-span and expires if not delivered on time. Such type of data include:
- Streamed media
- Video conferencing
- Online gaming
- Internet protocol television, etc.
QoS is an essential technique that sorts the data and ensures its timely delivery according to the priority. This enables the users to receive important data quickly, jitter-free and without the loss of data packets.
This time-critical data transfers through the UDP protocol which doesn’t transmit the lost packets of data again, unlike the TCP protocol. And the non-delivered data packet expires. This factor also makes it important for these data packets to reach their destination in time.
QoS sends out data in a store and forward manner that enables smooth data delivery, even if the nodes are not connected. QoS is configured to identify the RTP packets.
RTP or Real-time Transfer Protocol specialises in the delivery of audio-visual data packets.
What Do The Network Admins Need To Do To Reach This Scenario?
To favour the fast delivery of high priority data packets, the network admins first need to identify those packets.
They use the techniques of CoS – Class of Service and DSCP – Differentiated Service Code Point to identify important data that requires high priority on the bandwidth over others.
After identification, a queue has been made to maintain the order. Now, the routers and the switching devices are responsible to transfer the data fast and jitter-free by maintaining the order of the queue.
Network admins also have to ensure that the connecting devices placed between the sender and the receiver should be configured in a way that they can identify VIP data packets, maintain their queue, and deliver them on priority over other data types.
What Is the Importance Of QoS?
Technology is advancing at a fast pace along with the ways we manage and transmit data.
Now, calls and meetings are shifted to online meeting platforms like zoom and Skype, or video calls.
It was not the case a few years back and data was used to be much more simple. But now these applications use both audio and visual data, and the increasing importance of QoS stems from the same fact.
Now, QoS is required to ensure flawless connection and real-time data transfer.
The Qos Is Important In Data Transfer To Ensure Smooth Data Delivery And Avoid:
Data Latency – Latency refers to delay in transferring data packets. When the network doesn’t identify the priority, it sends high priority data packets in the same queue along with the non-urgent data packets. It creates an unnecessary delay in the real-time data transfer and creates data latency.
Jitter – The inconsistency in the speed and order of transmitting data packets results in jitter. It not only slows down the speed but also disturbs the order of data transfer, creating gaps or distortions in the audio or video being delivered.
Packet-loss – When the network treats every data packet with the same priority, packet-loss occurs.
Due to high network congestion, it discards the new data packets due to lack of space, even if the data is of high priority. It also creates gaps and irregularity while transmitting the data.
Loss of network credibility and reliability – A network can only match the users’ expectation by providing fast, jitter-free service with high-speed real-time data delivery.
If a network lacks in distinguishing between high and low priority data packets, that’s when the whole problem comes into the scene.
The users don’t get the required output and start losing trust in the respective network.
Loss of profits – The loss of credibility leads to fewer customers and an increased bounce rate. This surely decreases the profit and leads to dissatisfaction.
Mismanagement of internet resources – The mismanagement of internet resources occurs when they are not identified and aligned properly.
QoS helps in proper identification and alignment and thus prevents the mismanagement of data resources.
Top Tools for QoS Monitoring
QoS monitoring can be made easy with the use of some monitoring tools. These monitoring tools are highly essential for network admins. The tools are:
SolarWinds Net Flow Traffic Aanlyser
This tool helps in gauging the traffic flow and analysing that the QoS techniques are applied in the desired way. It analyses the network bandwidth performance.
ManageEngine Net Flow Analyzer
It offers a flow-based traffic analysis method by supporting S-Flow, J-Flow, and IPFIX. It also enables network admins to monitor the dispersed data networks through a single console or with the use of IOS and Android apps.
Paessler PRTG Network Monitor
PRTG Network Monitor helps to monitor traffic over different bandwidth with the use of a range of bandwidth monitoring sensors. The network can also raise alerts in case of network failures and protocol errors.
Nagios Network Analyzer
With this tool, you can have a topmost view of the network or can also monitor the usage of bandwidth consumption. It immediately points out if there is any deviation from the normal.
Why QoS Is The Need Of The Hour?
The utility of QoS is not only limited to the smooth transmission of the audio-visual content, but it is way more than that.
Now, as the IoT is on a rise, QoS is highly important for the smooth functionality of connected devices.
As an example shared by assignment help providers, in the manufacturing sector, the machines are using the network to share real-time updates with the engineers that keep them informed of the issues or if the unit is working smoothly.
Any variation in the data transfer can lead the company to incur big losses within seconds. All it needs to prevent such a situation is the efficient use of QoS.
Also, as we are approaching the era of the smart world, smart cars, buildings, and cities. It takes a lot of real-time data to be analysed or processed at the same time.
If the system is not efficient enough to process and prioritize the data, the system will not be able to work the way it should be.
Only the use of QoS can make this possible by filtering and prioritising data.
The data and its processes are advancing each day so it is a constantly upgrading field that needs regular monitoring and learning.
One good way to stay updated is to connect with the assignment help experts who are masters of the field and also capable to gauge future possibilities.
