服务水平协议（SLA）是指定服务提供商（SP）向客户交付的内容的文档。它们包含有关服务的信息，例如目标性能级别或每月可用性，以及对违反SLA的处罚。有关处罚的信息是必要的，因为如果SP没有交付所定义的内容，客户必须得到相应的补偿。然而，由于涉及大量的人工工作，当前的补偿过程是繁琐和复杂的。为了解决这个问题，本文提出了一种基于区块链和智能合约（SC）的方法来自动化补偿过程，同时在SLA生命周期内实现动态支付。在模拟服务提供商和客户之间的服务质量SLA管理的用例中，对建议的方法进行了评估。根据执行的评估，使用分散的解决方案成功地自动化了SLA管理流程的一部分，并且在没有第三方干预的情况下支付了补偿。
Service Level Agreements (SLA) are documents that specify what Service Providers (SP) are delivering to customers. They contain information about the service, such as target performance level or monthly availability, and penalties for the violations of the SLA. The information about the penalties is essential because if the SP does not deliver what is defined, the customer must be compensated accordingly. However, the current compensation process is cumbersome and complex because of the amount of involved manual effort. To address this issue, it is proposed in this paper an approach based on blockchain and Smart Contracts (SC) to automate the compensation process while enabling dynamic payments during the SLA lifetime. The proposed approach was evaluated in an use case that simulates the management of a Quality of Service SLA between an SP and a customer. Based on the performed evaluation, parts of the SLA management process were successfully automated using a decentralized solution, and the payment of the compensation occurred without the intervention of a third party.
