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.

Claim (Index 1):
A method comprising:\n sending, by a two-way active measurement protocol (TWAMP) control client on a centralized controller device of a network and to a TWAMP server on a first network device in the network over a first control connection, a first set of TWAMP control messages to negotiate a data session for a given service supported at the TWAMP server; sending, by the TWAMP control client and to a TWAMP session initiator on a second network device in the network over a second control connection, a second set of TWAMP control messages instructing the TWAMP session initiator to establish the data session for the given service with the TWAMP server; and receiving, by the TWAMP control client and from the TWAMP session initiator over the second control connection, service data measurements for the given service, wherein the service data measurements are collected by the TWAMP session initiator from the TWAMP server over the data session.
