In contrast to static allocation, which fixes time slots irrespective of usage patterns, dynamic allocation allows systems to allocate slots adaptively according to priority levels and traffic load. By guaranteeing that high-priority data streams get the bandwidth they require when needed, this frummynlexibility can greatly enhance network performance as a whole. Quality of Service (QoS) protocols implemented within the TDM framework are another successful tactic. QoS mechanisms make sure that critical applications have the resources they need to operate at their best by giving priority to some types of traffic over others. For example, in a business setting where email and video conferencing are used concurrently, QoS can guarantee that video packets are sent with the least amount of latency while permitting less urgent information, such as emails, to be sent during off-peak hours.
