What is QoS Shaping?

QoS Shaping or Quality of Service Shaping is a QoS strategy to gain granular control over how data passes over a network. The primary use case for shaping data comes from attempting to transmit data in a smooth, consistent manner. First, it's important to note that data transmission is often susceptible to inconsistencies, leading to variation in the traffic rate of data transmitted between a sender and receiver.

QoS Shaping simply uses memory cache to cache all of the outdoing data packets that could be susceptible to data transmission inconsistencies and sends them in a smooth, streamlined, consistent fashion. The benefit here is rather than seeing inconsistent spikes in data transmission; data will be transmitted in a smooth ordered fashion. This provides a great benefit to organizations as it allows for more dependable, consistent data transmission, alleviating data spikes and dropping of packets
