Service level expectations (SLEs) are divided into which two elements?

Service level expectations (SLEs) are crucial in defining the performance and quality standards of network services. They provide a framework for measuring and ensuring that the services delivered meet specific requirements. The two elements that SLEs are divided into are classifiers and sub-classifiers.

Classifiers are categories used to organize different types of network services or performance aspects. For example, a classifier might encompass a broad category like network availability or latency. Sub-classifiers then provide a more detailed breakdown within these broader classifications, enabling a more nuanced understanding of performance expectations. For instance, under the availability classifier, sub-classifiers could specify different types of services or applications, each with its unique service level considerations.

This division allows organizations to clearly communicate and manage customer expectations regarding service performance, ensuring that both providers and consumers have a shared understanding of service quality and delivery standards.
