The SLA is the entire agreement that specifies what service is to be provided, how it is supported, times, locations, costs, performance, and responsibilities of the parties involved. SLOs are specific measurable characteristics of the SLA such as availability, throughput, frequency, response time, or quality.
The term "Service Level Agreement" (SLA) is frequently used for all aspects of a service level, but in more precise use one may distinguish: [4] Service Level Indicator (SLI): measures of service level, like availability (uptime); Service Level Objective (SLO): objectives based on these indicators, like 99.95% availability;
For example, an SLA between a supplier (IT service provider) and the finance department of a large organization for the services such as finance system, payroll system, billing system, procurement/purchase system, etc. Service-based SLA: An agreement for all customers using the services being delivered by the service provider. For example:
Another memory trick to calculate the allowed downtime duration for an "-nines" availability percentage is to use the formula seconds per day. For example, 90% ("one nine") yields the exponent 4 − 1 = 3 {\displaystyle 4-1=3} , and therefore the allowed downtime is 8.64 × 10 3 {\displaystyle 8.64\times 10^{3}} seconds per day.
ITU-T Y.1564 is designed to serve as a network service level agreement (SLA) validation tool, ensuring that a service meets its guaranteed performance settings in a controlled test time, to ensure that all services carried by the network meet their SLA objectives at their maximum committed rate, and to perform medium- and long-term service testing, confirming that network elements can properly ...
Overall labor effectiveness (OLE) is a key performance indicator (KPI) that measures the utilization, performance, and quality of the workforce and its impact on productivity. Similar to overall equipment effectiveness (OEE), OLE measures availability, performance, and quality.
SLIs form the basis of service level objectives (SLOs), which in turn form the basis of service level agreements (SLAs); [1] an SLI can be called an SLA metric (also customer service metric, or simply service metric). Though every system is different in the services provided, often common SLIs are used.
The service performance test measures the ability of the DUT or network under test to forward multiple services while maintaining SLA conformance for each service. Services are generated at the CIR, where performance is guaranteed, and pass/fail assessment is performed on the KPI values for each service according to its SLA.
