Embodiment Construction

[0084] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0085] Embodiments of the present invention provide a NFV (Network Function Virtualization, network function virtualization) system, the structure of the NFV system refers to figure 1 As shown, the instantiation of Network Service (NS, Network Service) can be realized. A network service refers to an application running on a network, such as a web service, a video service, and the like.

[0086] NFV technology uses general-purpose hardware devices instead of d...

Abstract

The invention discloses a creation method of a virtual network instance, relates to the field of electronic information and aims to solve the problem that when multiple paths among internal virtual network units in a network service are available for data, the failure of determining one of the paths for transmission causes service interruption. According to a specific scheme, the method includes: acquiring network service descriptive information, determining virtual network units with expected instance creation according to the network service descriptive information, transmitting resource request information and connection information of the virtual network units with expected instance creation to a lower-layer device, transmitting path information to a network device of the lower-layer device, or transmitting the path information to each one of the virtual network units, and selecting the transmission path according to the path information when the data is under transmission among the virtual network units. The creation method is applied to creation of the virtual network instances.

Description

technical field [0001] The invention relates to the field of electronic information, in particular to a method and device for creating a virtual network instance. Background technique [0002] NFV (Network Function Virtualization, network function virtualization) uses general-purpose hardware devices and virtualization technology to realize the functions of some special-purpose devices in the network, so that network services no longer depend on special-purpose hardware devices, thereby reducing the cost of deploying special-purpose devices. cost. [0003] In the prior art, by creating an instance of NS (Network Service, network service), the virtual network service architecture can be implemented on physical hardware. For example, to define a VNF (Virtualized Network Function, virtual network function) unit in NS, And describe the connection relationship between each VNF unit. When the user applies the NS, data can be transmitted in the virtual network through the defined...
