How Can We Use AutoQoS to Protect Voice and Video Traffic?

Many companies are already using VoIP while incorporating video capabilities into their portfolio of services. One question that I am often asked is, “How can we ensure that the voice and video quality is good and consistent when using VoIP?”

What Traffic Goes Into Each QoS Class?

This is another topic of heated debate, and it changes from network to network, but I found a simple approach that works in most cases. Since I have four queues and four classes of traffic, I need to categorize my important traffic into four classes. Strictly for explanation purposes I took some liberty in defining four categories of traffic that are very effective in both large and small networks. These classes are: Real Time Protocol (RTP), Network Management (NetMgt), Business Critical, and the Default.

QoS: Keeping it Simple

Quality of Service (QoS) is a topic that causes a lot of debate and confusion in the networking community. Over the years, I’ve seen many implementations that were not effective for various reasons, mostly because they were either over-engineered or they fell short and did not protect the critical flows adequately. As a result, I found an approach that is very effective and quite simple and provides a QoS policy that is “just right” and can grow if required. The goal of this series of posts is not to teach you the ins and outs of implementation but to educate you enough about QoS so that you can build a QoS policy that is just right for your network.
