Abstract

The Web Services Agreement specification defines a normative language to formulate Service Level Agreements and a basic protocol to expose service-level descriptions, validate service-level requests, and come to an agreement. This protocol, often called “take-it-or-leave-it”, allows a service provider and a service consumer to decide whether to accept or reject a service offer. Although this approach is sufficient for a number of use cases, others exist with requirements for multi-step negotiation or the adaptation of an existing agreement. In this paper, we describe the Web Services Agreement Negotiation protocol, a proposal by the Open Grid Forum to extend the existing specification. This proposal is the result of combining various research activities that have been conducted to define protocols for negotiating service levels or to supersede the existing “take-it-or-leave-it” protocol. The main characteristics of this proposal are the multi-round negotiation capability, renegotiation capability, and compliance with the original specification.

WS-Agreement协商的建议

Web服务协议规范定义了一种规范语言来制定服务水平协议，并定义了一个基本协议来公开服务水平描述、验证服务水平请求并达成协议。该协议通常被称为“接受或放弃”，它允许服务提供者和服务消费者决定是否接受或拒绝服务提供。尽管这种方法对于许多用例来说是足够的，但是对于多步骤协商或对现有协议的适应的需求，还存在其他的用例。在本文中，我们描述了Web服务协议协商协议，这是一个由开放网格论坛提出的扩展现有规范的提议。这项建议是综合各种研究活动的结果，这些活动是为了确定谈判服务水平的协议或取代现有的“接受或放弃”协议而进行的。该方案的主要特点是具有多轮协商能力、再协商能力和对原规范的遵从性。
