共存在一個環(huán)境中。要提供平穩(wěn)的轉換過程,使得對現(xiàn)有的使用者影響最小,就需要有良好的轉換機制。ipv4向ipv6的演進應該是平滑漸進的,ipv4向ipv6的過渡需要相當長的時間才能完成,因此現(xiàn)在重點考慮的是ipv4與ipv6的共存及如何過渡的問題。在過渡時期,要解決相互通信的問題無非兩類:第一類就是ipv6之間互相通信的問題;第二類就是解決ipv6與ipv4之間的通信問題。 1.ipv4/lpv6過渡中的節(jié)點類型 在ipv4/lpv6過渡中定義了以下類型的節(jié)點。 (1)ipv4-only節(jié)點 ipv4-only節(jié)點僅實現(xiàn)了ipv4協(xié)議(并且只有ipv4地址)。這種節(jié)點不支持ipv6。當前大多數(shù)主機和路由器都是ipv4-only節(jié)點。 (2)ipvg-only節(jié)點 ipvg-only節(jié)點僅實現(xiàn)了ipv6(并且只有ipv6地址)。它只能與ipv6節(jié)點和應用程序通信。盡管這一類節(jié)點當前并不普遍,但是當小型設各(例如手機和掌上電腦等)實現(xiàn)了ipv6協(xié)議棧時,這種節(jié)點將會變得更為普及。 (3)ipv4/lpv6節(jié)點 這種節(jié)點既實現(xiàn)了ipv4協(xié)議,又實現(xiàn)了ip

電子(samsung electronics)推出的高階新品拉抬所致,德國27寸機種均價更因此止跌回升,結束連續(xù)4個月下滑的表現(xiàn)。中國市場9月各尺寸均價全數(shù)下跌,跌幅以24寸機種居冠,均價跌至人民幣1,716元,首次低于23寸,此因惠普(hp)有一款零售價近人民幣4,000元的機種下市,本月又無高階新款拉抬所致。 2011年9月起digitimes research street price將日本納入bdp零售價調(diào)查市場,同時因應其背景,追加搭載硬盤的錄放機,bdp分成純播放的“play only”及可儲存內(nèi)容的“recording type”兩種。其中2011年9月全球bdp市場play only均價203美元,較2011年8月微幅提高4.8%,此因9月初德國柏林舉辦ifa展,此為歐洲最大消費性電子展,bdp業(yè)者多會藉此發(fā)表新機,以sony最積極,除美國外,英、德、日及中國等4市場皆有新品上市,以致9月均價提升。 recording type方面,2011年9月全球均價898美元,是play only的五倍,較2011年8月增幅15.1%,此因日本市場推升價格上揚所致,包括son

of the noise. going back to our hand-waving analogy, you can demonstrate this principle for yourself. view a large text character (or an object around you), and view it by looking through a gap between your fingers. close the gap so that you can see only a portion of the character in any one position. now jiggle your hand back and forth. even though you can't see the entire character at any one instant, your brain will average and assemble the different views to put the characters together. it may l
