Description

Business chain management method and device

Technical field

The present invention relates to the field of communications technologies, and in particular, to a service chain management method and apparatus.

Background technique

As shown in FIG. 1 , in the existing common networking, a plurality of value-added service devices are often connected in series behind a fixed or mobile user access device, and the value-added service device may also be referred to as a service enabler (Enabler). The value-added service device may be a processing device for content optimization, acceleration, service flow compression, data caching, and the like. For example: video optimizer, traffic stream compressor, data buffer, deep message detector as described in FIG. The user access device may be a mobile broadband gateway GPRS support node (English: Gateway GPRS Support Node, GGSN for short) or a packet data gateway (English: Packet Data Network Gateway, P-GW for short), or a fixed access broadband. A network gateway (Broadband Network Gateway, BNG for short) or a service gateway (English: Serving GateWay, SGW for short).

The value-added service set and the path description processed by each value-added service device jointly form a service chain. Simply put, a business chain is a sequence of value-added services that a data stream needs to go through. For example, a sequence of value-added services required by a service chain may be as follows: content optimization, acceleration, traffic compression, and data caching. The data flow of different service chains only needs to flow through the value-added service equipment corresponding to the value-added service indicated by its service chain.

As shown in FIG. 2, it is an SDN (software defined network) GI (GI is a GPRS (General Packet Radio Service) under the network function virtualization (English: Network Functions Virtualization, NFV) architecture. Wireless service technology) The interface between the external packet data network and the network architecture diagram of the service chain.

The following logical features are included in the SDN GI service chain under the NFV architecture:

Value-Added Server (VAS) is used to provide services in the service chain, such as Web optimization, video optimization, unified resource locator, filtering, and so on.

Network Controller (English: Network Controller, NC for short) is used to provide maintenance and management of the service chain.

Forwarder (English: Forwarder), used to sense the service chain, identify and encapsulate the service chain header, forward user packets, service chain classification, and load balancing of value-added servers.

The VAS, NC, etc. are all virtual network function units in the virtual network or hybrid network (English: Virtual Network Function, VNF for short) or virtual network function components (VNFC). The sub-VNF in the VNF or the physical network function unit (English: Physical Network Function, PNF for short) may be an instance of a virtual machine (VM) running on a physical machine or distributed in multiple units. On a physical machine, it can be software running on a physical machine or distributed on multiple physical machines. It can also be a physical unit or a combination of multiple physical units that implement network functions.

The following logical features are also included in the SDN GI service chain under the NFV architecture:

The Sender is used to manage NFVO, and may be NMS/OSS (Network Management System/Operations Support System) or BSS (Business Support System) or NFVO itself.

The NFV Orchestrator (NFVO) is a business chain orchestrator responsible for the overall management of the business chain. For example, in the database, the business chain is recorded, modified, or updated with the overall information of the business chain. The overall information of the service chain includes the status of the service chain, the ID of the service chain, which VASs the service chain includes, which ports are interconnected by different VASs, and the CPU, storage resources, network resources, etc. occupied by the VAS.

A database for storing information about a business chain.

The virtual network function controller (English: Virtual Network Function Manager, VNFM for short) is used to manage each VAS. After receiving the management instruction of NFVO, it performs management operations on the VAS.

In the SDN GI service chain implementation under the NFV architecture, the management of the service chain is only managed separately for each VAS, and does not consider the relationship between the various VASs, and there are multiple VASs in relation to each other.
