To which QoS tool category does compressed RTP belong?

LLQ is a feature that provides a strict PQ to CBWFQ.
LLQ enables a single strict PQ within CBWFQ at the class level.
With LLQ, delay-sensitive data (in the PQ) is dequeued and sent first.
In a VoIP with LLQ implementation, voice traffic is placed in the strict PQ.
Compressed RTP (Real-time Transport Protocol) is a technique used to reduce the bandwidth usage of voice or video traffic by compressing the payload before transmission. In terms of QoS (Quality of Service), Compressed RTP falls under the category of link efficiency.
Link efficiency tools are used to maximize the utilization of available bandwidth while maintaining acceptable levels of voice and video quality. Compressed RTP is a link efficiency tool because it reduces the amount of data that needs to be transmitted over the network by compressing the voice or video payload.
Classification, marking, queuing, and prioritization are all other QoS tools that are used in different stages of network traffic management. Classification is used to identify traffic flows and apply policies based on traffic type, source, destination, etc. Marking is used to assign a specific QoS value to a packet based on its classification. Queuing is used to manage the order in which packets are transmitted. Prioritization is used to give higher priority to specific types of traffic, such as voice or video, over other types of traffic.
In summary, Compressed RTP is a link efficiency tool used to reduce bandwidth usage for voice or video traffic. It falls under the link efficiency category of QoS tools, which also includes fragmentation, header compression, and link compression.
