Telecom under the overall architecture of cloud computingNFVCloud solutions like figure2-36Shown.
Figure2-36 TelecomNFVCloud solutions architecture sub system combination
NFV(Function Virsualization NetworkNetwork function virtualization) is designed through the study of standardsITVirtual technology, the function of the telecommunication network equipment can be run in the software way to meet the industry standard of the large capacity of general server, switch and storage equipment to go. The software can be installed and unloaded on the hardware in different locations on the network, without the need to install new hardware devices. Simply say,NFVIs to introduce cloud computing platform in the platform layer, the network element of pure software, and hardware decoupling.
TelecomNFVCloud computing platform through the introduction of the cloud, the main problem to solve the operators are as follows:
Improve hardware investment income ratio
Simply said, the use of general-purpose hardware can greatly reduce the cost, on the other hand, the opening of new business do not need to change the hardware, as long as the corresponding software can be upgraded.
Improve business deployment flexibility
BecauseNFVMakes the software and hardware decoupling, that is, operators can be flexibly deployed in different machine frame and engine room, in different regions of the hardware, then the nature is greatly improved compared with the traditional business deployment flexibility.
Fast deployment service
The biggest advantage of soft hardware decoupling is that the device can focus on pure software level of research and development, in the existing software and hardware deployment, the new business development cycle will be greatly shortened, operators can also taste the sweetness of rapid deployment.
Automatic capacity expansion and energy saving and emission reduction
Due to the support of virtualization technology, the ability of network intelligent scheduling resources has been greatly improved. Network intelligent scheduling system can ease the business pressure by increasing the network resources in the service pressure. In the spare time, it can realize the energy saving and emission reduction through the automatic deletion of network resources.
Reduce the access threshold for the device
Hardware devices, the software interface is also common, there is no doubt that the access threshold of the device is reduced, but also to the telecommunications service to introduce more competition, these operators are the most want to see.
NFVHope of network element of pure software, but also need to provide telecommunication levelFiveANineThe high reliability of the service, so the cloud computing platform need to have higher requirements.
Cloud computing platform for TelecomNFVCloud's core value lies in:
OneDue to the requirement of reliability, the application of the virtual machine has different constraints on the affinity between the virtual machine, and the cloud computing platform supports all kinds of affinity scheduling requirements for telecommunication applications.
TwoTelecommunication service meansFiveANineThe high reliability, the service interruption time has the strict request, the cloud computing platform through the hardware fault fast detection and the fault fast notification technology, the telecommunication application can quickly perceive the breakdown, and promptly carries on the self healing mechanism to start, reduces the service interruption time.
ThreeAsNFVThe infrastructure, providing high reliability characteristics for application:HA(Availability HighThe characteristics of the characteristics of the virtual machine is mainly for the server failure mechanism, lightweightFT(Torrance FaultFor the webI/OThe application of a hot standby mechanism, and across the data center virtual machine recovery mechanism.
FourAgainstNFVCloud computing optimal forwarding, soVMToVMThe forwarding performance can meet the requirements of telecom network to.
FiveThe cloud computing platform utilizes the storage virtualization technology to bring all the servers locallyHDD,SAN,NASEquipment combination to build a large scale storage pool, the use of server memory/Flash/SSDConstruction of distributed high performance large capacity near endCacheGrid, the server machine head can be synchronized to the horizontal expansion, rightI/OReading and writing to provide linear acceleration. Cloud storage pool is also available on the basis ofSLAHierarchical storage service.
6)Cloud computing automation and template (TOSCA,HOT,CloudFormation,OVFThe characteristics can be greatly reduced by telecommunications applications andITOn-line efficiency of software application. Cloud computing's fault auto repair and automatic telescopic management capabilities can greatly reduce the complexity of the operation and maintenance of the business line.
SevenTelecomNFVIs a large-scale complex system, from telecommunications applicationsVNFToITA variety of applications, service users, online cover and contain everything, generate massive amounts of data. Cloud computing structured database, distributed object storage, semi structured storage (column storage database), as well as the message queue middleware capabilities, for TelecommunicationsNFVBring a wide range of operational capabilities, to meet the growing demand for new and old application of basic capabilities, to speed up the new business and new business applications on-line capabilities.
