Service Level Agreement (SLA)

Definition

A Service Level Agreement (SLA) is a formal document that outlines the expected level of service between a service provider and a customer. It typically includes specific metrics for measuring service performance, responsibilities of both parties, and consequences for failing to meet those standards. SLAs are crucial for ensuring that customers have a clear understanding of the services they will receive and for holding providers accountable to defined quality metrics.

Review Questions

• How does a Service Level Agreement (SLA) contribute to the overall Quality of Service (QoS) in network services?
  • A Service Level Agreement (SLA) directly impacts Quality of Service (QoS) by establishing clear performance metrics that need to be met by the service provider. These metrics, which can include latency, bandwidth, and availability, help ensure that users receive the level of service they expect. By setting these standards in an SLA, both the provider and customer have a framework for assessing service quality and addressing any issues that arise.
