SLA definition for the provision of an EF-based service
- …The evolution of mechanisms for providing Quality-of-Service (QoS) over the contemporary network infrastructures has introduced the need for regulation and management of the emerging QoS services with the use of Service Level Agreements (SLAs). SLAs for QoS-enabled networks move one step forward in …
