Mao Wei of researcher of Chinese Academy of Sciences thinks, the strategy that our country IPv4 transfers to IPv6 still is faced with number to weigh a challenge: The sequential estimation of the pressing sex of extinct to IPv4 address problem and generation is not worth whole society badly; Compare with IPv4 network photograph, at present IPv6 network still is in inchoate phase in the development of our country, had not entered extensive deploy to carry out level; IPv6 industry catenary is not perfect still, still be in what the industry grows to form level; Did not form centralized national address management to allocate a mechanism; In national level lack answers IPv4 address extinct and transfer to IPv6 the constituent mechanism with significant aspect, relevant system and measure, also do not have clear schedule.

中科院研究员毛伟认为，我国IPv4向IPv6过渡的战略还面临数重挑战：整个社会对IPv4地址耗尽问题的迫切性和产生的后果估计严重不足；与IPv4网络相比，现在IPv6网络在我国的发展仍处于早期阶段，还没有进入到广泛部署实施阶段；IPv6产业链还不完善，还处于产业发展的形成阶段；没有形成统一的全国性地址治理分配机制；在国家层面缺乏应对IPv4地址耗尽和向IPv6过渡方面有效的组织机制、相关制度与措施，也没有清楚的时间表。

Based on the management principle and objective of Jiangsu SNWDP, the thesis establishes its management framework and designs three management patterns and four modes. Through analyzing the anticipative management effect, scopes in point, advantages and disadvantages of each modes seriatim, the thesis confirms the recommended pattern. It makes framework refinement design, defines rights and duties of control level, execution level and participation level for the recommended pattern. According to the principles of planned water use, metered water use, contract water use, toll water use, it studies project operation for recommended pattern from four aspects, namely water supply plan, measure intensified, water supply contract, and water rate enacted. The thesis analyses and studies how to ensure water supply quality of Jiangsu SNWDP from three levels, including doing watershed protection, intensifying intermediate process, and establishing a long-term mechanism. It makes brief design for dispatching management applied system, studies emphases parts which may affect operation of the pattern in practice, also analyses dispatching optimization of Provincial boundary project management, pumping station management, and different water resources. Finally, the thesis studies relevant basal supports and development stratagems for the management of Jiangsu SNWDP.
