摘要 针对区分服务网络中基于服务级别约定(SLA)的实时协商问题,在分析协商优化过程后,提出一种满足确保转发服务的自动协商描述模型,模型包括一对一和一对多两种协商场景。通过模拟验证了模型的收敛性,并分析了在不同服务质量值和价格调节值下达成的协议方案性能。 Aiming at reahime negotiation based on SLA in DiftServ network, we propose an auto-negotiation model that guarantees AF（Assured Forwarding） service. The model represents two negotiation scenes, namely one to one and one to many. Moreover, model＇ s convergence is tested through simulations,then we analyse the agreement solution under different quality of service and price factor policy.
