Abstract

The invention is suitable for the field of network function virtualization and provides a network function virtualization implementation method, a wide-band network gateway and a control device. The wide-band network gateway BNG receives a message; a service chain is determined to process the message according to the received message, a strategy matched with the determined service chain is looked up from a strategy list, and multi-protocol tag switching MPLS service tags are added to the message; the message added with the MPLS service tags is sent to NFV servers or SPE. Therefore, the tag of each NFV server used for processing the service chain is once and directly added to a message header to enable a front NFV server to forward to a next NFV server after processing the service, continuous processing is achieved, meanwhile, each NFV server does not need to send return to the BNG after processing the service, and furthermore, the occupation of network flow is greatly reduced while the processing efficiency of the service chain is improved.

Description

technical field [0001] The invention belongs to the field of network function virtualization, and in particular relates to a method for realizing network function virtualization, a broadband network gateway and a control device. Background technique [0002] Accompanied by the large increase in the types and quantities of equipment in the operator's network, the technical problem of urgently needing to reduce the construction cost and operation and maintenance cost was born. In order to solve this technical problem, Network Functions Virtualization (Network Functions Virtualization, NFV) was proposed. )technology. At the same time, NFV technology can also adapt to the business diversity requirements in the cloud computing environment. The basic principle of NFV technology is: through virtualization technology, the network service functions that originally required multiple device types (such as firewalls, load balancers, etc.) and multiple physical device forms to provide t...
