Final answer:
The protocol used for load balancing and traffic prioritization is QoS (Quality of Service), which helps manage network resources to ensure optimal performance for sensitive data like voice and video.
Step-by-step explanation:
The protocol used by technologies for load balancing and prioritizing traffic is QoS, which stands for Quality of Service. QoS is a set of technologies and techniques designed to manage network resources and ensure the optimal performance of certain types of traffic, which may be more sensitive to network delays and disruptions, such as voice and video.
QoS mechanisms can be implemented in routers, switches, and other networking devices to prioritize traffic. This means that more important or time-sensitive data is transmitted first, reducing the chance of jitter, latency, and packet loss. For example, a VoIP call might be given priority over file downloads to ensure clear and uninterrupted communication.
