It is not uncommon for an internet service provider (or network service provider) to explicitly state its own ALS on its website.   The U.S. Telecommunications Act of 1996 does not specifically require companies to have ALS, but it does provide a framework for companies to do so in Sections 251 and 252.  Section 252 (c) (1) (« Duty to Negotiate ») obliges z.B. established local exchange operators (CIDs) to negotiate in good faith matters such as the sale of dentes` and access to whistleblowing channels. A web service level agreement (WSLA) is a standard for monitoring compliance with web services according to the service level agreement. It allows authors to indicate performance metrics assigned to a web application, desired performance goals, and actions to perform if performance is not achieved. You enter into service-level SLA or Service-based ALS if multiple parties use a service or product from a supplier. The « multi-level ALS » can also be a service-based, customer-based combination of ALS. The goal of an ALS is to achieve the quality of a service in measurable indicators.
This level of service must be achieved by the contractor in his activities for the client and, depending on the type of contract, he must maintain it for a longer period of time. The aim is to make the control possibilities for the client transparent and to accurately describe overly safe performance characteristics such as performance level, reaction time and speed of machining. An important element is the level of service, which describes the agreed quality of service and contains information about the range of services (e.g. time. B, volume), availability, supplier response time, etc. The typical example is the operation of servers, which are 24 hours a day, 7 days a week with a maximum z.B failure rate of 0.1% per year and a response time of 30 minutes after reporting the damage by an external service provider that must be.  Many SLAs follow the specifications of the COMPUTER infrastructure library when applied to IT services. Since the late 1980s, SLAs have been used by fixed-line operators. Today, ALS is so widespread that large organizations have many different ALSs within the company itself. Two different units in an organization script an ALS, one unit being the customer and another the service provider. This helps maintain the same quality of service between different units of the organization and in several sites within the organization.
This internal ALS script also compares the quality of service between an internal service and an external service provider.  A Service Level Contract (SLA) is an obligation between a service provider and a customer.
