IT outsourcing agreements, in which the remuneration of service providers is linked to the results obtained, have gained popularity, with companies developing from time and pure materials or full-time price models. SLAs are available for almost all types of service, from traditional T-carrier services to frame relays. Internet service providers (ISPs) also offer SLAs for ip-based virtual private networks (VPNs), intranets and ex-trannets. Some ISPs even guarantee a degree of accessibility to their DF Remote Access customers. IBM, for example, offers alS for its remote customers, which guarantees a 95% success rate for DF connections to IBM Global Network. Security – All security measures taken by the service provider are defined. This is usually the development and consensus on antipoaching, computer security and confidentiality agreements. A service level contract is an agreement between two or more parties, one being the customer and other service providers. It may be a formal or informal legally binding “treaty” (for example. B internal relations within the department). The agreement may include separate organizations or different teams within an organization.

Contracts between the service provider and other third parties are often referred to as SLAs (wrongly) – the level of service having been set by the (main) customer, there can be no “agreement” between third parties; these agreements are simply “contracts.” However, operational agreements or olea agreements can be used by internal groups to support ALS. If an aspect of a service has not been agreed with the customer, it is not an “ALS.” AlS should have two components: services and management. ML-compatible proactive error management has recently been designed as a powerful way to ensure reliable network operation [70]. Instead of using conventional, pre-developed, solid pre-processing solutions, this new mechanism relies on dynamic data operations that use huge amounts of operational data recovered via network monitors (for example). B using a simple network management protocol). The data repository can include the parameters of network components such as optical power levels on different network nodes, EPA gains, power consumption and electricity consumption of different devices, shelf temperature, temperatures of different critical devices, etc. ML-based error prediction tools are able to learn historical error patterns in networks and detect hidden correlations between different entities and events through effective data analytics. These unique and powerful features are extremely beneficial for proactively detecting errors and preventative maintenance mechanisms on optical networks. Figure 21.30 shows different error management tasks supported by ml-based data analysis in optical networks, including proactive error detection, error classification, error geolocation, error detection and error recovery. The service received by the customer as a result of the service provided is at the heart of the service level agreement.

In addition to defining the services to be provided, the contract should also document how services should be controlled, including how data is collected and reported, how often it is verified, and who is involved in the audit. Set a good base number. Defining the right measures is only half the fight. To be useful, measures must be set at reasonable and achievable performance levels. In the absence of solid historical measurement data, you should be prepared to review and adjust parameters later through a predefined process specified in ALS. SLAs can also be used internally to indicate what network users can expect from IT staff and network-related procedures.
