: Establishing agreements between service providers and end-users, followed by resource reservation and admission control.
: Tracking real-time performance and initiating corrective actions (renegotiation) if service levels drop below the agreed threshold. Implementation Mechanisms rld-qos.iso
According to the ISO/IEC standard, QoS management is typically structured into three functional stages: and enforce service levels.
: Translating user-level requirements into technical network parameters. rld-qos.iso
The framework identifies several key quality characteristics that must be managed to ensure stable and predictable performance:
This standard provides a universal model for managing QoS across various network entities. It defines how QoS-related information flows between participants and describes the mechanisms used to monitor, negotiate, and enforce service levels.
