Five years is the watershed of sdn/nfv, and within ten years, it will change from solo to chorus

sdn/nfv is no longer a new vocabulary, but the enthusiasm for it in the industry has not declined at all. Wei Leping, chairman of sdn/nfv industry alliance and director of China Telecom Science and Technology Commission, pointed out that sdn/nfv is currently in the stage of on-site test, trial commercial use and early commercial use as a whole. It has entered a development period in and a stable development period in

coincidentally, Cao Jiguang, director of the technical expert committee of sdn/nfv industry alliance, will regard five years as the watershed of sdn/nfv. Within five years, sdn/nfv will gradually break the closed structure of single manufacturer solo, and within ten years, it will no longer be a solo of single manufacturer, but a chorus of multiple manufacturers

sdn/nfv industry has entered a period of development in years.

in Wei Leping's view, the overall industrial technical performance of sdn/nfv is not satisfactory, and the effect of increasing revenue and reducing expenditure is not obvious, regardless of the slow progress of standards and commercialization. Sdn/nfv is currently in the stage of on-site test, trial commercial and early commercial, that is, it is still in the stage of Gatner curve from transition expectation to disillusionment to maturity. It is estimated that the year will enter a period of development and the year will enter a period of stable development

when talking about the development trend of sdn/nfv, Wei Leping believes that at present, Internet application companies, cloud computing service providers and a few large operators are leading the development of sdn/nfv

Internet application companies and large cloud service companies are now deploying SDNS in and between data centers. It is reported that the main purposes of deploying SDN in the data center are: network virtualization, cloud business, tenant isolation, ZTP zero configuration deployment, etc; It mainly improves chain utilization, ensures QoS, and optimizes real-time traffic

however, the vast majority of enterprises in the enterprise park network and the enterprise internal data center have not yet considered the shear thickening characteristics of particulate suspension system and its influencing factors, and plan to deploy Sdn. The main reason is the lack of urgent needs (including unattractive new businesses, limited space to reduce costs), and they believe that the time to deploy SDN is still early

mainstream operators began the concept verification in 2014, and entered the field test/trial commercial stage in 2015. Individual operators have begun large-scale commercial deployment (ATT). On the whole, except for individual fields, the technology is still immature, and the progress of standardization and commercialization is still relatively slow. Wei Leping said that operators are moving from the POC stage to the trial and early commercial stage, and the progress is not fast, and the collaborative choreographer is becoming a common focus. Operators need to build software thinking and development capabilities, but the degree of involvement and the evolution from vendor SDN to open SDN, the oil delivery valve of 5. Control pressure testing machine, will be difficult

and it is understood that 63% of operators do not think that pure open source nfv can meet the requirements of carrier level availability and reliability. In other words, commercial software based on open source vendors will still be the mainstream solution

within ten years, sdn/nfv will change from a single manufacturer solo to a multi manufacturer chorus

similar to Wei Leping's point of view, Cao Jiguang, director of the technical expert committee of sdn/nfv industry alliance, will regard five years as the watershed of sdn/nfv. In the next five years, the market of sdn/nfv will cover data center groups, DCI interconnection, optical network, access, mobile core, IMS and other fields, and the domestic market size is close to 250billion

however, within five years, sdn/nfv is mainly the initial stage of development characterized by technological competition and cooperation, pilot application, and concept cultivation. The key is to unify the architecture, standardize the excuses, promote the maturity of products that meet the requirements of carrier grade, gradually break the closed architecture that manufacturers dance alone, create an open system platform, and promote the integration of multiple manufacturers. Cao Jiguang said

some scenarios of operators (such as data center group, DIC interconnection, vcpe, vepc and VIMS, etc.) from field test to small-scale commercial deployment lay the foundation for intelligent transformation of network architecture for users and businesses, cultivate operation and maintenance personnel, and accumulate operation and maintenance experience

in, it entered the stage of integrated application characterized by mature technology, scale deployment and operational change. The open network target architecture is clearer, and the platform and interface are more standardized; Products and solutions are increasingly mature, no longer a solo of a single manufacturer, but a chorus of multiple manufacturers. A win-win industrial ecosystem has initially taken shape. Operators will deploy sdn/nfv technology on a larger scale in order to achieve the overall goals of open and programmable network, flexible resource scheduling, rapid business launch and efficient operation and maintenance

at the same time, in terms of standards, after the competition and cooperation of technical standards in the past two years, the positioning between SDOs has become increasingly clear, and Kaiyuan has accelerated the subversion of the R & D mode of technical standards in the traditional CI field

moreover, nfv promotes the deconstruction of hardware and software, as well as the hierarchical deconstruction of software functions, further refines and lengthens the industrial chain, and the industrial center will be adjusted from hard to soft. The industrial value of software companies, especially third-party system integrators, is highlighted

the whole software and hardware integrated system originally provided by a single manufacturer will be decomposed into components from different manufacturers, such as general hardware, virtualization platform, different vnfs, etc. Third party system service integrators will play a more important role in the nfv industrial ecosystem, requiring stronger software R & D and system integration capabilities

traditional communication equipment enterprises need to adapt to the change of this industrial ecosystem, actively build an industrial ecosystem around their own platform, provide open architecture products and solutions, and integrate components from different service providers. Cao Jiguang said

however, Cao Jiguang also pointed out that the deployment of nfv will be a gradual process, and traditional networks and nfv will coexist for a long time. At the same time, the deployment principle of nfv is demand-oriented, intermediate design, major changes in hardware and software, business driven, efficiency first, from easy to difficult

the three operators have different transformation visions, and nfv has a common choice

now, telecom operators have begun to enter the key development stage of the transformation to information services. Building a new generation network with globally schedulable resources, fully open capabilities, elastic capacity contraction, and flexible architecture has become an important direction for the evolution and development of operator networks

moreover, Wei Leping also pointed out that in the coordinated development of the industry, we should seek common ground while reserving minor differences, keep warm together, strive to avoid the practical risks of standards and industrial chain fragmentation, and operators should play a greater role

it is understood that China Mobile has released novonet2020 vision, hoping to reduce hardware costs, realize resource sharing across systems, increase network flexibility and accelerate network deployment through the separation of software and hardware. However, what China Mobile needs to do is to give priority to new business network units, such as signaling bin

Chinatelecom released its b2i strategy to promote the evolution of the network through the cooperation of nfv and Sdn. As explained by 3A composite company, the structure is simple, agile, open and intensive, providing visual, on-demand and self-management network capabilities. However, Chinatelecom needs to carry out nfv laboratory testing and promote layered deconstruction: carry out practical experiments such as EPC virtualization and bras virtualization, and gradually promote nfv commercial deployment after accumulating deployment experience; Virtualization elements are deployed to DC in a unified manner, promoting the transformation of CO to DC

China Unicom proposes a new generation network architecture cube-net2.0, which uses sdn/nfv to build an intensive network oriented to network cloud, so as to realize network and services. Therefore, China Unicom gives priority to nfv solutions and upgrades traditional service products in core, business chain, fixed access, data network and other fields
