關(guān)鍵字:IPv6 IPv4
對于那些可能不知道或不了解正式推出 IPv6 象征什么意義的讀者們,這里將簡單介紹這個規(guī)格是什么以及為什么會成為全球經(jīng)濟(jì)持續(xù)依賴網(wǎng)際網(wǎng)絡(luò)的一個重要里程碑。 IPv6 延續(xù) IPv4 而來,它是管理全球網(wǎng)絡(luò)使用的最新技術(shù)協(xié)議,如同網(wǎng)絡(luò)協(xié)會在其官網(wǎng)上的用戶指南中所解釋的:
“......獨(dú)特的32位數(shù)字,可找出用戶的計算機(jī)網(wǎng)絡(luò)位置。它可作為用戶計算機(jī)的‘街道地址’,激活其它計算機(jī)去找出用戶的確切所在,并傳送信息給用戶。”
而這種專業(yè)技術(shù)跟我們有什么關(guān)系呢?由于上一代的 IPv4 網(wǎng)際網(wǎng)絡(luò)協(xié)議(IP)已用罄所有可用的 IP 地址,這意味著用戶在透過智能手機(jī)、平板電腦、智能家電、打印機(jī)以及各種可連網(wǎng)設(shè)備的爆發(fā)性網(wǎng)絡(luò)使用體驗(yàn)可能因?yàn)樵O(shè)備缺乏IP地址而受限。網(wǎng)際網(wǎng)絡(luò)協(xié)會在其聲明中說:
“根據(jù)號碼資源組織(Number Resource Organization,NRO),全球 IPv4 地址已經(jīng)在2011年4月耗盡。現(xiàn)在唯一能做的就是將 IP 進(jìn)一步劃分成更小部份或交換已經(jīng)分配過的──但這可能會變得更加復(fù)雜,并危及用戶的隱私。“
對于重度依賴網(wǎng)絡(luò)應(yīng)用程序利用率持續(xù)成長的通訊、數(shù)據(jù)與連網(wǎng)服務(wù)供貨商、電信設(shè)備制造商、 ISP ,以及像 Google 、 Facebook 等公司,都已經(jīng)十分敏銳地意識到這一點(diǎn)了。這就是為什么許多這些廠商們在一年前展開合作,首次在全球激活 IPv6 試行,經(jīng)過一年后,終于在上周正式發(fā)布 IPv6 了!這一次,來自全球的400多家公司與組織均參與了此次的規(guī)格發(fā)布。包括Akamai、Facebook、Google與Yahoo等幾家公司也已經(jīng)將 其所有的內(nèi)容全部轉(zhuǎn)移到IPv6了。
在IPv6于全球發(fā)布前,業(yè)界已采取了一些中間步驟。對于開發(fā)中的經(jīng)濟(jì)區(qū)域,從終端用戶 的角度來看,其中最重要的一次或許是 Semana IPv6 ──針對采用 IPv4 版(現(xiàn)仍廣泛部署)的網(wǎng)絡(luò)服務(wù)與即將發(fā)布的 IPv 6之間是否完全兼容的南美互通作業(yè)性測試大會。一些主要地區(qū)的電信業(yè)者、 ISP 以及來自拉丁美加勒比海等洲與的其它機(jī)構(gòu)都參與了這次由巴西召集安排的會議。
對于設(shè)計工程師和其它創(chuàng)新者也帶來了一些意義。以前,我著重于公司如何在其產(chǎn)品中加入連接性設(shè)計。這就是物聯(lián)網(wǎng)(IoT)。 然而,一個新的范例正發(fā)展出一個未來所有具連接能力的產(chǎn)品都將會以實(shí)現(xiàn)這個 IoT 的目標(biāo)而設(shè)計的。
意大利米蘭理工大學(xué)的Maurizio Decina并首次宣布,所有的創(chuàng)新者之間正形成一個共識──擘劃出一個由物聯(lián)網(wǎng)管理的未來。這意味著,人們和企業(yè)最常共同使用的對象將擁有隨插即可聯(lián)網(wǎng)的能力。
對于電子產(chǎn)品制造商,未來將在各經(jīng)濟(jì)領(lǐng)域開啟更多機(jī)會,并在消費(fèi)者、制造業(yè)、醫(yī)療、工業(yè)與服務(wù)市場引爆對于現(xiàn)有電子 產(chǎn)品附加更多功能的需求。這種可提供預(yù)定產(chǎn)品的可能性最近已在歐洲針對數(shù)字產(chǎn)業(yè)召開的NEXt大會上加以討論了。坦白說,我以前從沒有想過 IPv6 能因?yàn)橄嬖?IPv4 內(nèi)的原有限制,因而進(jìn)一步推動了這些創(chuàng)新。
即使是以市場演進(jìn)的觀點(diǎn)來看,根據(jù)在此領(lǐng)域最積極活躍 的Truth Dare Double Dare公司共同創(chuàng)辦人Jeremy Tai Abbett表示,接下來,我們將看到一大堆新創(chuàng)公司成立,他們將以探索跨學(xué)科的途徑,開發(fā)下一代物聯(lián)網(wǎng)產(chǎn)品。順便說一下,所有的產(chǎn)品并不一定得是數(shù)字化的裝置:許多非數(shù)字化的產(chǎn)品將會附加可聯(lián)網(wǎng)的工具,甚至包括一些你常丟在抽屜中不用的東西!
Connectivity Beyond Digital Products

One year after the first initial trial, World IPV6 is finally becoming a reality. Major telecommunication companies, Internet service providers, Web companies, and networking equipment vendors are teaming up to accelerate the deployment and adoption of the technology in key economic regions of the globe. The Internet Society on June 6 summed it up in a statement noting: "This time it is for real." It's undoubtedly the case that there's no going back on IPv6, but what does this mean for your business and customers' operations?
For those who may not know or understand the significance of the formal launch of IPv6, here's a primer on what it is and why this is a significant milestone for the continued reliance of the global economy on the Internet. IPv6 succeeds IPv4 and is the latest technical protocol governing the use of the Internet globally. IPv6, as the Internet Society explains in a User's Guide on its Website, is a:
...unique 32-bit number that identifies the location of your computer network. It serves as your computer's 'street address,' enabling other computers to find out exactly where you are and deliver information to you.
Why should you bother about such technicalities? Because IPv4, the preceding Internet protocol, has exhausted all its available IP addresses, which means the exploding use and adoption of Web-ready devices, including smartphones, tablet PCs, smart household gadgets, printers, and others, could be crimped by lack of IP addresses for the equipment. The Internet Society said in the above-referenced statement:
According to the Number Resource Organization, the world officially ran out of IPv4 address in February 2011. All that can be done now is to divide the allocated properties into ever-smaller portions or trade what's already been assigned -- moves that could complicate and compromise your privacy.
Communications, data, and networking service providers, manufacturers of telecom equipment, ISPs, and companies like Google, Facebook, and others that are heavily dependent on continued growth in the use of Web applications are keenly aware of this. That's why many of these companies one year ago teamed up to run the first global trial of IPv6, an event now eclipsed by last week's formal launch of the new Internet protocol. This time, more than 400 companies and organizations from around the world took part in the launch. Several, including Akamai, Facebook, Google, and Yahoo have transitioned their entire content to IPv6 from the older protocol.
Several intermediate steps were taken before the global launch. One of the most important, from the end users' perspective for developing economic regions, was probably SemanaIPv6, the South American testing conference for full interoperability between Internet services working with current IPv4 version (still mostly deployed) and the incoming IPv6. The major regional telecom operators, ISPs, and other institutions from all over Latin America and the Caribbean attended the event, which was coordinated from Brazil.
There are implications for design engineers and other innovators too. In a previous blog, I focused on how companies are trying to design connectivity into their products. I called this the Internet of Things. A new paradigm is developing, however, one that in the future assumes all products that have the capability for connectivity will be designed with that goal in mind. This emerging consensus among innovators -- announced for the first time by Maurizio Dècina of Italy's Politecnico di Milano -- projects a future governed by the phrase "Internet of Things." This implies that the most common objects used by people and enterprises would have the capability to "plug" into the Internet.
For electronics manufacturers, this future would open up opportunities in all segments of the economy and explode current demand for electronics add-ons in consumer, manufacturing, medical, industrial, and service markets. This possibility to deliver bespoke products was recently discussed at NEXt, the leading European conference for the digital industry. Honestly, I never thought before about the innovations IPv6 could foster by removing constraints inherent in the finite nature of IPv4.
Even in terms of market evolution, according to Jeremy Tai Abbett, creative partner and co-founder of Truth Dare Double Dare, and one of the most active people in the sector, we are going to see an explosion in the number of newly formed startup companies that will explore multi-disciplinary approaches to developing the next generation of Internet of Things products. By the way, not all of these products will be digital devices: Many non-digital things will be enhanced with connectivity tools, including some items you regularly toss into a drawer!
