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。

Think , essential points messenger our country education reform of investment and financing systems gets the main body of a book expect effect, to must carry out reformation on budgetary allocations currently in effect system , enlarge investment in higher education by state revenue and expenditure first; Need to expand the higher education funds source channel secondly , encourage an institute to raise funds from many channels , build the fine mechanism ensuring that educational appropriations increases by steadily; Third needs to reform now available cost compensating mechanism, charging perfecting higher education system,Draw the advanced experience that higher education cost compensates abroad, the science sum perfects the tuition fee system using our country especially; Fourth is going to reinforce the operation managing and having an effect to higher education funds supervision , to improve fund sigmatism efficiency , applies the modern finance implement to raise funds and by being innovative.

本文认为，要使我国教育投融资体制改革取得预期成效，首先必须对现行的财政拨款制度进行改革，加大国家财政对高等教育的投入；其次要扩大高等教育经费的来源渠道，鼓励高等院校从多渠道筹措资金，建立保证教育经费稳步增长的良好机制；第三要改革现有的成本补偿机制，完善高等教育的收费制度，借鉴国外高等教育成本补偿的先进经验，使我国的学费制度更科学和完善；第四要加强对高等教育经费的监督管理和有效运作、提高资金的使用效率，并通过创新运用现代金融工具筹措资。

Currently some different video transmission scehmes have been proposed, such as source-based adaptive rate control, receiver-based simulcast and layered multicast, but these schemes basically follow the traditional network design principles and take end-to-end congestion control and error control mechanisms without the participation of network intermediate nodes, making a series of problems such as session management difficulty, congestion control blindness, feedback explosion, and the difficulty in achieving fairness among different users.

目前对于网络视频传输已出现了各种不同的解决方案，如基于源的自适应速率控制方案和基于接收端的联播、分层多播等视频传输机制，但这些方案基本上都遵循网络设计的传统原则，采取基于端到端的拥塞控制和差错控制机制，而没有网络节点的参与，从而导致会话管理困难、拥塞控制盲目、反馈爆炸等一系列问题，而且难以在用户之间达成公平。
