What is the 4-Class Strategy Of QoS?

QoS (Quality of service) in enterprise-grade information networks can be a complicated subject. There are multiple methods for implementing QoS policies, and some of those methods are better suited for some jobs while others are not. QoS is utilized to ensure that network traffic can prioritize itself and flow through the network with as few hiccups as possible while guaranteeing a certain SLA. One of the strategies used for QoS policies is a 4-class strategy.

The 4-class strategy is one of the simpler QoS strategies to implement. This strategy focuses on implementing QoS policies for things like telephony, signaling, and mission-critical applications. It's important to note that even within this strategy, QoS policies are still managed by the type of data transmission. For instance, voice communication is often assigned as real-time while signaling network traffic will reserve 7% of link bandwidth. Likewise, mission-critical data can reserve 35% of bandwidth, too.
