For IT people, Sdn's challenge is to choose the right SDN solution for the right technology use case at the right time. Here are 12 tips for enterprise IT managers that can be used to evaluate SDN products from different SDN vendors.

1 What Benefits SDN technology will bring to the enterprise, there must be a clear vision, including how it will affect the legacy network infrastructure. How to plan SDN will have a long-term impact on the overall network of the enterprise.

2 SDN is still at a very early stage-markets, standards and technology are still to be matured. Therefore it purchasers must be tested and carefully evaluated before selecting a particular SDN architecture.

3 Assess the impact of SDN on the IT department. Does SDN provide opportunities to create cross-functional teams, such as servers, storage, and networking, to address data center or cloud network requirements?

8 Consider SDN from the point of view of business value. Can a specific SDN product reduce costs or improve it operational efficiency? SDN is not just a technical problem.

9) security. Improving network security is a key potential advantage of SDN. Can the SDN solution you consider improve security, or can it handle additional security challenges?

10 Standard support. Can SDN support a wide range of industry standards, which refer to both network standards (such as openflow) and it standards (such as server virtualization products)?
