A service level agreement (SLA) is an obligation between a service provider and a customer. Particular aspects of the service – quality, availability, responsibilities – are agreed between the service provider and the service user.  The most common component of an SLA is that services must be provided to the customer as contractually agreed. For example, Internet service providers and telecommunications companies will typically include service level agreements in the terms of their contracts with customers to define the service level(s) sold in plain language. In this case, the SLA usually deconstructs a technical definition in the intermediate period between failures (MTBF), average repair time or mean recovery time (MTTR); identification of the party responsible for reporting errors or paying fees; responsibility for different data rates; throughput; Jitter; or similar measurable details. Such an agreement is intended for two purposes. First, it protects the Agency that provides the data and ensures that the data is not misused. Joint agreements are most effective when they are declared at the beginning of an event. The purpose of setting up common agreements must be clearly indicated, they are established in groups, the moderator asks if anyone needs clarification or if he has any questions. It is important that everyone in space agrees with the proposed list of agreements. This can be done by asking if someone can`t live with this list or by asking everyone to give a thumbs up if they agree with the list.
