What type of traffic is classified as not resilient to loss?

The classification of traffic that is not resilient to loss refers to types of communications that, when disrupted or lost, significantly impair the quality or usability of the information being transmitted. In this context, data traffic includes a wide range of applications that are sensitive to packet loss.

While video and voice traffic are also susceptible to loss, they often employ strategies like buffering and error correction to mitigate the effects of lost packets, resulting in a more resilient experience despite potential disruptions. Network management traffic, on the other hand, is specialized and typically does not often suffer severe usability issues with packet loss, as its traffic is usually transmitted in bursts and can afford some delays.

Data traffic, however, includes various types of applications, such as file transfers or web traffic, where packet loss can lead to incomplete data. Unlike voice and video, which prioritize real-time delivery, data traffic often requires complete and intact packets for successful transmission. Therefore, in a situation of packet loss, data traffic has a lower tolerance and is more critically impacted. This is why data traffic is classified as not resilient to loss.
