Abstract: Techniques are described for extending a two-way active measurement protocol (TWAMP) to enable measurement of service key performance indicators (KPIs) in a software defined network (SDN) and network function virtualization (NFV) architecture. The TWAMP extensions enable control messaging to be handled by a TWAMP control client executed on a centralized controller, and data messaging to be handled by a TWAMP session initiator executed on a separate network device. Techniques are also described for extending TWAMP to enable measurement of any of a plurality of service KPIs for a given service supported at a TWAMP server. The service KPIs may include one or more of keepalive measurements, round trip time measurements, path delay measurements, service latency measurements, or service load measurements. The TWAMP extensions for the service KPIs may be used in both conventional network architectures and in SDN and NFV architectures.

Abstract translation: 描述了用于扩展双向主动测量协议（TWAMP）的技术，以便能够测量软件定义网络（SDN）和网络功能虚拟化（NFV）架构中的服务关键性能指标（KPI）。 TWAMP扩展使得控制消息传递能够由在集中式控制器上执行的TWAMP控制客户端来处理，数据消息传送将由在单独的网络设备上执行的TWAMP会话启动器处理。 还描述了用于扩展TWAMP以使得能够测量TWAMP服务器上支持的给定服务的多个服务KPI中的任何一个的技术。 服务KPI可以包括保持性测量，往返时间测量，路径延迟测量，服务等待时间测量或服务负载测量中的一个或多个。 用于服务KPI的TWAMP扩展可以用于传统网络架构和SDN和NFV架构中。
