4.下一代因特网(NGI)Internet 2与其他先进联网技术之间的关系
    由大学领导的Intern以2和由联邦政府领导的NGI都是以基于美国的开创性工作,二者是并行的互为补充的。Internet 2与NGI已经在许多方面携手共进。例如通过参加美国国家科基金会NGI计划,己有超过150个研究Internet 2的大学通过竞争获得授权,成为支持连接诸如Abilene大学试验网和甚高性能主干网络这类高级骨干网的一部分。Internet 2也正在与全世界类似的先进网络倡导者形成伙伴关系。共同工作将有助于保证研究和教育的紧密结合并提供协同工作的先进联网基础设施以及与全球因特网的持续协同工作性。

5.什么是Internet 2的长期目标
    这一努力的一个关键目标是加速先进因特网技术的扩散,特别是渗透到商业领域中。这种情况下,Internet 2将有助于维持美国在互联网技术中的领导地位。Internet 2也会为非大学的教育团体成员带来好处,特别是从幼儿园、中小学校和公共图书馆。Internet 2及其成员的目标是与尽可能广的计算机用户共享他们的技术。这一方法是第一代Internet的特点,并且今天依然如此。对于研究Internet 2的大学,这意味着可以在他们的校园内提供高性能联网——使他们投资的校园网升级并联结到国家Internet 2主干网上。对于Internet合作伙伴,这意味着在Internet 2的开创中与Internet 2的大学的积极合作。
