Contracting Protocol Clause Samples

Contracting Protocol. Our approach to combine business entities and make them cooperate is of decentralized nature. Several bilateral contracts in form of SLAs and OLAs are required between entities to enable a combined real-time service delivery. Therefore, a contracting protocol based on the exchange of XML documents was developed to show different steps of the contracting process. The single steps of the XML-based Contracting Protocol (XCP) are shown in Figure 2 and described below. Compared to the previously introduced E-Commerce scenario of Figure 1, the XCP is illustrated as a contracting process between one CSP, a single end-customer, and three intermediate ISPs.
