What happens if we do not use QoS in networking?

Not having a correctly configured QoS could result in one (or all) of the following issues: Latency : When the RTP packets haven’t been assigned their required priorities they will be delivered at the devices’ default speeds. In a congested network, the packets have to travel along with the rest of the non-urgent packets. While network latency itself won’t have an effect on the quality of the delivered audiovisual data per se, it will affect communication between end-users. At 100ms of latency, they will start talking on top of one another as the packets arrive out of sync, and at 300ms the conversation stops being comprehensible. Jitter : Real-time applications remove standard transport level buffering, so there is no mechanism to reassemble arriving packets in the correct order. Jitter is the irregular speed of packets on a network. It can result in packets arriving late and out of sequence. As the application does not wait for the stream to be assembled correctly, out of sequence pa
