The non-technical challenges faced by SDN

Editor's note: At present, both the Internet and the telecommunications industry, the acceptance of SDN is increasingly high. However,the business ofSDN still needs to address a range of challenges, especially from non-technical areas.

at present, the acceptance of SDN is becoming more and more high both in the Internet and in the telecom industry. However,the business ofSDN still needs to address a range of challenges, especially from non-technical areas. SDN industry Alliance recently released the White Paper on the development of SDN industry, which considers that the Commercial deployment of SDN measures ROI, integrates the industrial chain, Application innovation and the internal system of telecom operators need to respond positively and take corresponding measures.

An accurate assessment of return on investment

How to accurately assess the ROI of SDN is still a huge challenge. on the one hand, the introduction ofSDN Technology will have an impact on the overall value pattern of the network. In the past, the network consisted of special hardware and software system with specific functions, in which the price of hardware occupies a large proportion in the network cost. Today,SDN uses standardized hardware to implement various functions of the network elements by loading different software. Therefore, the cost of hardware will be greatly reduced, the value of software will be significantly improved. How to evaluate the impact of two kinds of construction network model on network cost, and the lack of authoritative evaluation standard at present. On the other hand, due to the lack of large-scale successful commercial deployment cases, the evaluation of the introduction of SDN technology to help operators save investment costs and operational complexity of the problem, there is insufficient data support.

Second, stimulate the application of innovation vitality

The realization of the core business value of SDN technology requires new revenue by stimulating innovative vitality. This demand is fully embodied in the SDN layered architecture model, especially the network capability is open to the upper level application, through the Service Sense network resource utilization condition, realizes the flexible resource dispatch to satisfy the business to the resource dynamic demand, improves the user experience and innovates the business model, Thus bringing new revenue to the business. However, the opening of the network capability is still in its infancy, and the application innovation based on SDN Architecture is just beginning, and most network operators are still focusing on how to use SDN Technology to reduce the cost of network construction and operation, to a certain extent, restricts the new revenue that SDN technology may bring.

Iii. effective integration of the industrial chain

The SDN industry chain involves a number of links, and the industry is now mainly using open source mode to integrate the advantages of all sources. But, in additionto research and development capabilities like Google andFacebook , which can be customized to develop SDN solutions based on open source outcomes , Most users often rely on the device provider's solution. At the same time, different aspects of their own interests for the consideration of the SDN Understanding is not the same, the use of what technology line in the industry has not reached a consensus, so most vendors in the open source research and development solutions based on the often add some private content, This increases the complexity of the integrated industrial chain.

Iv. transforming the intrinsic genes of telecom operators

sdn ip Department is responsible for data network, wireless department is responsible for wireless networks. But in sdn technology architecture, business overlap and crossover, There is no clear boundary between the departments. For example, in " ip+ ip The network and optical transmission network for unified path calculation and protection coordination, and so on, requires to break the existing departmental boundaries within the operator, need to be able to work closely with the various independent departments. Therefore, how to make the operators planning and construction, transport and it Such departments are coordinated rather than fragmentation, which is sdn new requirements and new challenges.
