Embodiment Construction

[0033] Before describing the implementation of this application in detail, the architecture of NFV is described as follows:

[0034] The architecture of NFV running on the server is as follows: Figure 4 As shown, it mainly includes four parts, namely: VNF module (VNF), network function virtualization infrastructure (Network Functions Virtualization Infrastructure, NFVI), virtual network function manager (Virtualized Network Function Manager, VNFM) and network function virtualization Network Functions Virtualization Orchestrator (NFVO). Among them, VNF represents a network function implemented by software. NFVI is responsible for the abstraction of physical resources, including virtual networks, virtual computing, and virtual storage. VNFM is responsible for the life cycle management and configuration of VNF. NFVO is responsible for the management of VNF service flow. The architecture of NFV may also include a virtualized infrastructure manager (Virtualized Infrastructure ...

Abstract

The embodiment of the application provides a method and device for implementing a virtual network function (VNF) service chain, relating to the technical field of networks, and aiming to solve the problem that a VNF service chain does not support the VNF deployment with a transparent mode, or does not support the VNF deployment with the mixed transparent mode and routing mode. The scheme includesthe following steps: a server determines an abstract data model, wherein the abstract data model includes a classifier and a port pair group list; and the server determines a service chain according to the classifier and the port pair group list, wherein the port pair group list includes at least one port pair, the port pair includes an input port and an output port of a VNF module, and for each port pair, the port pair is in the routing mode or the transparent mode. The scheme of the application can be applied in an NFV orchestration technology.

Description

technical field [0001] The present application relates to the field of network technology, and in particular to a method and device for realizing a virtual network function service chain. Background technique [0002] Network Functions Virtualization (Network Functions Virtualization, NFV) is a new type of network technology led by operators. The purpose is to carry related network functions through x86 general hardware architecture and virtualization technology, thereby reducing the cost of purchasing dedicated network equipment. By decoupling network functions from dedicated devices, network functions are no longer strongly dependent on dedicated hardware, which can effectively solve the problem of reasonable sharing and reuse of resources, and accelerate the launch and innovation of new services. At the same time, for actual network services, it can Achieve on-demand flexible deployment, elastic scaling, fault detection and recovery. In the NFV technology, for the deploy...
