Embodiment Construction

[0028] figure 1 is a block diagram illustrating an example network system including a software defined networking (SDN) based network and network function virtualization (NFV) based network architecture according to the techniques described herein. figure 1 The exemplary network system 1 includes a service provider network 2 operating as a private network to provide packet-based network services to subscriber devices 16 . That is, the service provider network 2 provides authentication and establishment of network access for the subscriber device 16 so that the subscriber device can begin exchanging packets with the public network 12, which may be an internal or external packet-based network, such as the Internet.

[0029] as in figure 1 As shown in , the service provider network 2 includes software-defined networking (SDN) and network function virtualization (NFV) architectures. SDN controller device 14 may provide a high-level controller for configuring and managing the rou...

Abstract

The present disclosure describes a communication method, a centralized controller device for a network, and a network device in the network. A technology that extends the Two-Way Active Measurement Protocol (TWAMP) to enable measurement of service key performance indicators (KPIs) in software-defined networking (SDN) and network function virtualization (NFV) architectures. The TWAMP extension enables control messages to be processed by a TWAMP Control Client executing on a centralized controller device, and data messages to be processed by a TWAMP Session Initiator executing on a separate network device. Also described is a technique for extending TWAMP to enable measurement of any of a number of service KPIs for a given service supported at the TWAMP server. Service KPIs may include one or more of keep-alive measurements, round-trip time measurements, path delay measurements, service delay measurements, and service load measurements. TWAMP extensions for service KPIs can be used in traditional network architectures as well as in SDN and NFV architectures.

Description

[0001] This application claims priority benefit of Indian Patent Application No. 2616 / CHE / 2015 filed May 25, 2015, the entire contents of which are hereby incorporated by reference. technical field [0002] The present disclosure relates to communication networks. Background technique [0003] A network architecture has been developed based on the concepts of integrated software-defined networking (SDN) and network functions virtualization (NFV). SDN includes the separation of control plane and data plane in network nodes similar to network devices such as routers and switches, and the abstraction of the control plane into more modules and layered structures. NFV uses virtualization to remove the dependency on specialized hardware and enable the consolidation of many different network equipment types onto industry-standard high-capacity servers, switches, and storage, which can be located in data centers, network nodes, and end-users. In SDN and NFV architectures, latency a...
