Abstract

The embodiments of the invention disclose a flow control method and apparatus under NFV configuration. The method comprises the following steps: virtualizing multiple virtual resources for independently running service on a physical resource, at the same time, dividing the physical resource into multiple sub physical resources, wherein there are corresponding relations between the virtual resources and the sub physical resource; obtaining preset mapping relations between service priorities and the virtual resources, and according to the preset mapping relations between the service priorities and the virtual resources, arranging priorities for the virtual resources; and when physical resource congestion is caused by a service flow burst, according to the priorities of the virtual resources and the corresponding relations between the virtual resources and the sub physical resources, controlling the sub physical resources used by the virtual resources. According to the invention, normal operation of important service can be guaranteed under the NFV configuration in case of large-flow impact, and the system reliability is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a flow control method and device under the NFV framework. Background technique [0002] Under the network function virtualization (NetworkFunctionVirtualization, NFV) architecture, network element functions are provided in the form of software running on virtual resources, that is, virtual network functions (VNF, VirtualizedNetworkFunction). In this way, the system can run multiple network elements at the same time. Provide different services. In order to improve system reliability and ensure service quality, the NFV system needs to perform flow control when physical resources are congested due to large traffic bursts. At present, Ethernet ports mainly use the traditional flow control mechanism for flow control, that is, when the business traffic is large and resource congestion occurs, the flow control is unified for all services without dist...
