The volume of apps and devices on the market, paired with the rise of social media, has led to a flood of network traffic and compromised network performance. As a result, IT departments are bombarded with cases involving frustrating delays, broken images, dropped calls and fragmented video conferences, all of which bring productivity to a standstill.
Here QoS means quality of service, the network comes into play. Folded into most network monitoring tools is the ability to manage and monitor network traffic by a class of service methods. These QoS monitoring tools can empower system administrators to determine whether existing QoS policies effectively prioritize traffic and provide a positive end-user experience.
While there are many network monitoring options on the market, my favorite is the SolarWinds ® NetFlow Traffic Analyzer . This robust platform reaches the heart of QoS monitoring and is easy to use, allowing system administrators in organizations large and small to crash into the running ground the moment they are installed.
What is QoS and why is it necessary?
To truly understand the role of network service quality, we need to look at the meaning of QoS in general. I like to think of QoS as a form of traffic control. Every day, a company's network is bombed by a traffic attack. Some of this traffic is critical to the success of business operations, and some, while important, are not critical or do not require time-sensitive delivery.
For example, many companies rely on File Transfer Protocol (FTP) as well as video conferencing applications such as Zoom or GoToMeeting. Above all, FTP packets are not as latency sensitive as Voice Over Internet Protocol (VoIP) packets, both for employee productivity. If delayed, FTP packets still arrive intact. A delayed VoIP package, on the other hand, risks becoming fragmented, ultimately resulting in discrete video calls and ineffective business meetings.
To better manage the mountainous amount of data packets traveling through the network, QoS policing has improved. Consider QoS policies as the traffic police who guide drivers during a busy 5K road race. Likewise, a traffic cop assesses when to prioritize drivers versus runners, QoS policies allow network administrators to prioritize which applications should receive delivery preference over others.
QoS policies are essential for any company that relies on delay-sensitive applications-consider media streaming, host video searches, etc. - in daily operations. They are “essential” as they are an integral part of the functioning and performance of your delay-sensitive applications. Without QoS policies in place, the quality of delivered data can be greatly compromised.
