加拿大Alberta省的阿尔伯达超级网络(AlbertaSuperNet)在今年第一期IEEESpec鄄trum杂志上被评为将来宽带网络和业务发展的模型。为追踪这个网络的发展历史,本期专栏找到了美国华尔街公司报告(WSCR)2002年6月采访主要建设商AxiaNetMedia公司首席执行官ArthurR.Price先生的访谈文章和其它一些相关资料。阿尔伯达超级网络的信息给我们提供的重要启示是:宽带网络的发展在促进社会信息化的同时,也要做到有利于减小社会的数字鸿沟。21世纪的到来,使日本东京一个城市的电话总数超过整个非洲,欧洲芬兰一个国家的电脑主机总数超过拉丁美洲,整个非洲的互联网业务量只占全世界的0.2%。数字鸿沟不仅将贫富拉开、也将城乡分开。发达地区宽带的发展使人们可以沉溺于游戏、影视、聊天,而贫困地区电话普及甚低,人们还在为教育和就业奔走奋斗。ITU在2003年底对178个国家的数字接入指数DAI(一个基于教育程度、互联网接入费用可承担度、高速用户的比例和网络可用带宽等的综合指标)进行了评估,前三名是欧洲三国瑞典、丹麦和冰岛,第四名是韩国,香港和台湾排第七和第九,中国排第84位。阿尔伯达超级网络的构思和实践一方面体现了他们在缩小数字鸿沟方面的经验。他们在网络建设的策略上是既发展接入,同时从一开始就重视宽带应用,
AlbertaSuperNet in Alberta, Canada, was named the model for future broadband networking and business development in the first issue of IEEESpec-trum magazine this year. In order to track the history of this network, this issue of the column finds interviews with the Arthur R. Price, chief executive of AxiaNetMedia, a major construction firm, in June 2002 by the Wall Street Journal Report (WSCR) and other relevant sources. The important revelation provided by the information provided by the Alberta hyper-network is that the development of broadband networks should promote social informatization as well as help to reduce the digital divide in society. In the 21st century, the total number of telephones in a city in Tokyo in Japan surpassed that in Africa as a whole. The total number of hosts in one Finnish country in Europe surpassed that of Latin America and the Internet traffic in Africa as a whole accounted for only 0.2% of the world’s total. The digital divide not only opens the gap between the rich and the poor, but also separates the urban and rural areas. The development of broadband in the developed regions makes it possible for people to indulge in games, movies and chatting, while the telephone coverage in poor areas is very low. People are still fighting for education and employment. In late 2003, the ITU conducted a survey of the DAI (a composite index based on education level, affordability of Internet access, proportion of high-speed users and available network bandwidth) of 178 countries. The top three were Europe Three countries Sweden, Denmark and Iceland, the fourth is South Korea, Hong Kong and Taiwan ranked seventh and ninth, China ranked 84th. The ideas and practices of the Alberta SuperNet on the one hand reflect their experience in bridging the digital divide. They are both in the strategy of network construction to develop access, from the beginning emphasis on broadband applications,
