Embodiment 1

[0031] Embodiment 1 of the present invention provides a method for testing network elements of an NFV core network. The steps of the method can be as follows figure 2 shown, including:

[0032] Step 101, receiving a control primitive.

[0033] In this step, the test capability layer in the test instrument can receive the specified control primitive sent by the adaptation layer under the MANO architecture through the specified control primitive application programming interface (API).

[0034] That is, in this embodiment, a new adaptation layer can be constructed under the MANO architecture, and the control of the test instrument can be realized by sending control primitives through the adaptation layer.

[0035] In each embodiment of the present invention, the test instrument may be a test instrument in the form of special hardware existing in the prior art, or a virtual instrument using X86 general hardware. That is, the test capability layer in the test instrument may not...

Embodiment 2

[0059] Embodiment 2 of the present invention provides a method for testing network elements of an NFV core network, and the steps of the method can be as follows Figure 4 shown, including:

[0060] Step 201, the test instrument checks whether the state of the test resource is normal.

[0061] If normal, continue to execute step 203, otherwise, execute step 2021.

[0062] Step 2021, feedback to the MANO framework.

[0063] If the test instrument detects that the state of the test resource is abnormal, it may feed back the information that the state of the test resource is abnormal to the MANO architecture (the adaptation layer in it), and continue to execute step 2022 .

[0064] Step 2022, re-initialize test resources.

[0065] In this step, the test instrument can re-initialize the test resources and end this process.

[0066] Step 203, receiving configuration primitives.

[0067] If the test instrument checks that the state of the test resource is normal, the adaptation...

Embodiment 3

[0084] Embodiment 3 of the present invention provides an NFV core network element testing framework, the structure of which can be as follows Figure 5 As shown, it includes a network element under test 11, a test instrument 12, and a management and orchestration MANO architecture 13, which includes an adaptation layer 131 under the MANO architecture 13, wherein:

[0085] The adaptation layer 131 included under the MANO architecture 13 is used to send specified control primitives to the test capability layer of the test instrument 12 through specified control primitive APIs;

[0086] The test capability layer of the test instrument 12 is used for simulating the surrounding network elements of the network element under test 11 according to the specified control primitive to realize the full-envelope test of the network element under test 11 .

[0087] The MANO architecture 13 also includes a virtual network function manager 132 and a virtual infrastructure manager 133, wherein:...

Abstract

The invention relates to the technical field of networks, in particular to an NFV (Network Function Virtualization) core network element test method, architecture and MANO architecture. According to the scheme, the method comprises the following steps: constructing an adaptation layer under an original MANO architecture; and the adaptation layer sending a specified control primitive to the test capability layer of the test instrument through the specified control primitive API, so that the control of the test instrument is realized under the MANO architecture in a centralized manner, and the unified deployment and scheduling of the test capability of the test instrument by the MANO architecture are realized through the design of the control primitive.

Description

technical field [0001] The present invention relates to the field of network technology, in particular to a network function virtualization (NFV, Network Function Virtualization) core network element testing method, framework and management and orchestration (MANO) framework. Background technique [0002] At present, NFV core network elements (hereinafter referred to as NFV network elements) are composed of a hardware layer, a virtualization layer (such as a network function virtualization infrastructure solution (NFVI)) and a virtualized network function (VNF) layer. Under the MANO architecture, the VNF layer of NFV network elements is managed through the virtual network function manager (VNFM), and the virtual layer of NFV network elements is managed through the virtual infrastructure manager (VIM), so as to realize the orchestration of NFV network elements , pull up and other operation controls. When testing NFV network elements, the test instrument simulates surrounding...
