Problems solved by technology

While SDN and NFV can reduce the need for dedicated hardware for network functions or related services, issues can arise when deploying virtualized network functions in complex network topologies
For example, in an environment using NFV, it may be more difficult to test, troubleshoot and isolate faults

Embodiment Construction

[0016] figure 1 is a diagram showing a computing environment 100 for testing network function virtualization (NFV), according to an embodiment of the subject matter described herein. Computing environment 100 may include one or more networks and / or one or more computer platforms, nodes or devices. refer to figure 1 , computing environment 100 may include one or more controller applications 102 , tester controllers 104 and / or network controllers 106 .

[0017] Controller application 102 may represent any suitable entity or entities (eg, software executing on a hardware processor) for providing various instructions, configuration, and / or other information to network controller 106 . For example, the controller application 102 may include a network builder for managing policies and service levels across network resources (eg, servers, data storage devices, and / or switches) using automated workflow, provisioning, and other resource management techniques. In this example, the ne...

Abstract

Methods, systems, and computer readable media for testing network function virtualization (NFV) are disclosed. According to one method, the method occurs at a network test controller implemented usingat least one processor. The method includes determining, using network configuration information, a first insertion point for inserting a first network function tester (NFT) into a service chain comprising a plurality of virtualized network functions (VNFs). The method also includes configuring the first NFT to analyze or ignore traffic matching filtering information, wherein the traffic traverses the first NFT from at least one VNF of the plurality of VNFs. The method further includes inserting, at the first insertion point, the first NFT into the service chain.

Description

[0001] priority statement [0002] This application claims the benefit of US Patent Application Serial No. 14 / 939,674, filed November 12, 2015, which is hereby incorporated by reference in its entirety. technical field [0003] The topics described in this article relate to network virtualization. More specifically, the subject matter relates to methods, systems, and computer-readable media for testing network function virtualization (NFV). Background technique [0004] Deployments leveraging service chaining architectures are becoming more common using network functions virtualization (NFV) and software-defined networking (SDN). For example, a service chaining deployment may involve multiple virtualized network functions connected or chained together to perform one or more services. In this example, each virtualized network function may include one or more virtual machines (VMs) implemented in various hardware, virtualized containers, and / or using other software. While S...
