基于MPLS VPN的气象宽带网络测试系统

Network test system of meteorological broadband network based on MPLS VPN

针对MPLS VPN多节点间的QoS等网络性能的测试,分析了MPLS VPN网络的测试对象和测试特点,利用网格计算的思想,提出了一种分布式运行的网络测试软件设计方法。将控制、通信和测试模块分层封装形成独立子系统,并提出了一种基于时序构造不同等级数据流的QoS测试算法,使用黑盒测试。通过气象宽带网络测试系统的实例,验证了设计与开销均较好的满足了MPLS VPN网络的测试需求,有效衡量运营商服务等级协议。

To test quality of service （QoS） and network performance among muti-nodes of MPLS VPN, test objects and characteristics of MPLS VPN are analyzed, a distributed operation network test software based on grid computing is designed, package control, communication and test modules are layered into independent subsystems, a sequence-based QoS test algorithm on different levels of data flow is designed and black-box test is used. An application case of Meteorological broadband network test system, shows that the design and cost satisfy the MPLS VPN network test, ISP＇ s service level agreement （SLA） is effectively measured.
