摘要
资源共享是解决资源短缺、提高整体生产力的有效方法。基于服务水平合同(Service Level Agreement,SLA)的资源买卖属于以市场经济为基础的资源共享环境。由于目前基于SLA的网上买卖协议(Protocol)没有SLA交易条件协商过程支持,所以系统无法有效地对交易过程提供协商功能。SNAP(Service Negotiation and Acquisition Protocol)是基于SLA的信息协议方案,本文对原来SNAP方案基础上增加交易条件协商过程的描写,并提供具体系统建设使用的方法,最后以"全国贵重与优质教育资源共享"项目为背景进行了的使用验证。
Resource sharing is an effective way to increase overall productivity with limited resources. Service Level Agreement （SLA） based resource trading is resource sharing through market economy. The current SLA-based information protocols do not support trading price negotiation process; therefore online SLA trading systems cannot provide online negotiation function. SNAP is a SLA based information protocol; this paper extends the original SNAP proposal to support negotiation process and provides a practical system architecture design; at the end, an actual system implementation example is given based on China Education Resource Sharing （CERS） project.
