摘要： 针对区分服务网络中多域间基于服务级别约定（SLA）的实时协商问题，在分析协商过程中消费者和服务者的优化目标和约束后，从系统平衡的角度，提出一种多域间的动态协商模型。此模型能够减少价格的频繁抖动，提高资源分配的有效性，并给出一个具体的协商场景实例。最后通过实验验证了模型的有效性。
关键词: 多域, 协商, 动态, 服务级别约定
Abstract: Aiming at realtime negotiation based on Service Level Agreement（SLA） between multi-domain in DiffServ network，a dynamic negotiation model based on system equilibrium is proposed after analyzing the optimization object and constrains for consumers and network providers.The model can alleviate price fluctuation and achieve efficient resource allocation.Then one negotiation case based on the model is presented.Moreover，the model’s performance is tested through simulations.
Key words: multi-domain, negotiation, dynamic, Service Level Agreement（SLA）
