And network server device.
Background technique
It virtualizes content distributing network (Virtual Content Delivery Network, referred to as vCDN), even if
With virtualization technologies such as network function virtualizations (Network Function Virtualization, referred to as NFV), will pass
The component part of system content distributing network CDN, such as edge service node, content center, dispatching control center, with virtualization
VNF form is deployed in novel telecom cloud computer room.VCDN can increase and expand according to load situation of change dynamic adjustment service capacity
Appearance/capacity reducing flexibility so that fringe node can remote-control, simple installation greatly shortens business on-line time, realizes close rapidly
Real-time service ability elastic telescopic, realizes the guarantee and optimization of network service.
Novel telecom cloud is with NFV/ software defined network (Software Defined Network, referred to as SDN) for two
Big core technology basis, novel telecom cloud (Telecom Integrated Cloud, referred to as TIC) node pass through by SDN structure
At new network connection, complicated and diversified traditional machine room is developed as unified data center, the Novel electric of distribution is formed
Believe cloud infrastructure, traditional Network Management System is developed into the management arranging system of automation, realizes the automation of network
Layout and intelligent management.
As shown in Figure 1, the peripheral system and network element of virtualization content distributing network vCDN access include: that network function is virtual
Change composer (Network Functions Virtualisation Orchestrator, referred to as NFVO), (virtual network
Functional manager Virtualised Network Function Manager, referred to as VNFM), virtualized infrastructure management
Device (Virtualised Infrastructure Manager, referred to as VIM), Element management system (Element
Management System, referred to as EMS), network function virtualized infrastructure (Network Functions
Virtualisation Infrastructure, referred to as NFVI) and shared cloud storage system.
The integrated stand composition of CDN system according to Fig.2, is usually analyzed from business scenario and functional requirement, vCDN tune
Spend operation management system (Operations Management System, referred to as OMS), the Dispatching Control System of distributing layer
TCS can add X86 common hardware server disposition based on existing business software, without being realized using virtualization NFV mode.
Most be necessary to adopt virtualization technology is the edge service node (SNS) of edge service layer, as the CDN of CP client
When node serve flow has dynamic change, the edge service node based on virtualization technology can be adjusted according to the variation of flow at any time
The empty machine resource allocation of vCDN VNF, realizes dynamic dilatation or capacity reducing, to meet newly-increased flow demand, or release is empty
Not busy empty machine resource.
Currently, the capacity of the existing edge service node VNF for realizing vCDN of industry is adjusted to Passive Mode, as VNF
Cpu load or network interface flow load be arranged two trigger values, one be dilatation trigger value, one be capacity reducing trigger value.Work as reality
The running VNF related load in border increases, and when reaching dilatation trigger value, if cpu load is more than 80%, then starts VNF dilatation behaviour
Make, to the more resources of virtual machine of VIM application.When cpu load is lower than 20%, then starts the operation of VNF capacity reducing, discharged to VIM
A part of resources of virtual machine.
Therefore, the service ability dilatation of prior art vCDN edge service node or capacity reducing are the loads based on vCDN VNF
Situation is monitored by VNFM and is passively realized according to preset configuration parameter.However it is directed to the practical business scene of CDN, have
A large amount of operation demands are needed before actual access pressure change occurs, and are needed in advance actively to vCDN fringe node service energy
Power is deployed.Current industry is not directed to vCDN scene, and CDN and TIC active collaboration provide the scheme or key of service guarantee
