4.下一代因特網(wǎng)(NGI)Internet 2與其他先進聯(lián)網(wǎng)技術(shù)之間的關(guān)系
由大學(xué)領(lǐng)導(dǎo)的Intern以2和由聯(lián)邦政府領(lǐng)導(dǎo)的NGI都是以基于美國的開創(chuàng)性工作,二者是并行的互為補充的。Internet 2與NGI已經(jīng)在許多方面攜手共進。例如通過參加美國國家科基金會NGI計劃,己有超過150個研究Internet 2的大學(xué)通過競爭獲得授權(quán),成為支持連接諸如Abilene大學(xué)試驗網(wǎng)和甚高性能主干網(wǎng)絡(luò)這類高級骨干網(wǎng)的一部分。Internet 2也正在與全世界類似的先進網(wǎng)絡(luò)倡導(dǎo)者形成伙伴關(guān)系。共同工作將有助于保證研究和教育的緊密結(jié)合并提供協(xié)同工作的先進聯(lián)網(wǎng)基礎(chǔ)設(shè)施以及與全球因特網(wǎng)的持續(xù)協(xié)同工作性。
5.什么是Internet 2的長期目標(biāo)
這一努力的一個關(guān)鍵目標(biāo)是加速先進因特網(wǎng)技術(shù)的擴散,特別是滲透到商業(yè)領(lǐng)域中。這種情況下,Internet 2將有助于維持美國在互聯(lián)網(wǎng)技術(shù)中的領(lǐng)導(dǎo)地位。Internet 2也會為非大學(xué)的教育團體成員帶來好處,特別是從幼兒園、中小學(xué)校和公共圖書館。Internet 2及其成員的目標(biāo)是與盡可能廣的計算機用戶共享他們的技術(shù)。這一方法是第一代Internet的特點,并且今天依然如此。對于研究Internet 2的大學(xué),這意味著可以在他們的校園內(nèi)提供高性能聯(lián)網(wǎng)——使他們投資的校園網(wǎng)升級并聯(lián)結(jié)到國家Internet 2主干網(wǎng)上。對于Internet合作伙伴,這意味著在Internet 2的開創(chuàng)中與Internet 2的大學(xué)的積極合作。
