Description
Technical field
The present invention relates to the communications fields, in particular to a kind of tactful processing method and processing device.
Background technique
In the related art, network function virtualization (Network Functions Virtualization, referred to as
NFV) it is to be proposed by telecommunication network operators, refers to by IT virtualization technology, using the large capacity service of industrywide standard
Device, memory and interchanger carry the technical standard of various network software functions, and the main thought of NFV is by network function
Energy software is all deployed in the virtual machine in commerce server, rather than is individually deployed in its private network device.NFV is realized
The flexible load of software, realize in the flexible deployment configuration in each position such as data center, network node and user terminal, thus plus
The speed of fast network deployment and adjustment, reduces the complexity of service deployment, improves the unitized of the network equipment, generalization, adaptation
Property etc..
Under NFV scene after the network element deployment completion of operator brings into operation, for the network service quality being optimal
With saving resource, reduction energy consumption, elastic threshold value is provided with to key index.When threshold value reaches resilient expansion, according to jerk-finger
Corresponding elastic surface and elastic step-length are marked, corresponding empty machine and module are popped up, after network element receives empty machine, will be carried out at load balancing
Reason reduces the load of former processing module, provides network service quality.When threshold value reaches elastic shrinkage, according to elastic index pair
The elastic surface answered and elastic step-length, the corresponding empty machine of bullet contracting and module, before elasticity, network element will be notified, and removes empty machine
On business, then virtual network function manager VNFM (Virtualized Network Function Managers) will
Corresponding empty machine is deleted, resource and energy consumption are saved.In addition some is detected for load balancing scene between network element, such as network element oneself
KPI Key Performance Indicator KPI (Key Performance Indicator) is abnormal, triggering upper level network element modification distribution policy or on
Grade network element detects that some KPI of lower level network element is abnormal, and triggering upper level network element modification distribution policy etc. requires corresponding strategy
Module completes different policy actions according to policing rule.
Under current NFV scene, most of policy management module is all and network function virtualization controller NFVO
(Network Functions Virtualization Orchestrator) or VNFM are coupled, while being directed to net
Network function (Network Function, referred to as NF) strategy and network service (Network Service, referred to as NS) strategy
There is different policy module processing, does not have Universal and scalability, paralell currently towards micro services can not be met
The needs of structure also increase each module maintenance cost.
Complex for management tactful in NFV scene in the related technology, the high problem of maintenance cost does not have also at present
There is effective solution scheme.
