Studies on Interoperability of Broadband Networks

美国国家科学基金会（NSF）提供的超高速骨干网服务（vBNS）是第一个高速研究网络。自1998年以来，阿比林一直作为Internet2项目开展的下一代互联网开发的试验台运作，是整合全球互联网研究活动的焦点网络。与欧洲国家类似，日本的SINET从1999年10月开始与阿比林连接，以便与日本研究人员一起参与Internet2项目。加拿大的CA^*net3、跨欧洲网络（TEN-155）、德国的DFN、法国的RENATER、荷兰的SURFNET以及北欧的NORDUnet，这些国内和区域高速研究网络相互连接，为研究创造了全球基础设施。研究的目的是维持和发展研究网络的全球宽带连通性。2000年的研究总结如下：(1) 5月，在英国伯明翰举行的世界电信大会上，研究人员提出了进展报告和建议，并在同一地点举办了IPv6会议，以便将IPv6部署到全球研究通信中。(2)研究人员提出了未来宽带网络的流量设计，其中新的统计现象“自相似性”已成为重新考虑带宽设计的主要项目。(3)研究人员参加了10月在美国亚特兰大举行的Internet2年度成员会议，以协调全球宽带连接并讨论未来向全球光子研究网络过渡的计划。(4) 12月在蒙特利尔参加加拿大研究网络CA^*net3年会，就建立广域光子研究网络进行技术讨论，包括未来亚太地区与加拿大光子研究网络互联的协调。在三年的时间里，该研究通过建立网络化的研究环境，通过世界范围的协调和技术开发，保持研究的传播质量和有效性，为日本的研究人员和日本的学术研究做出了贡献。同时，通过确定21世纪的技术发展和创造新概念，启动未来的安排，即为光子研究网络做准备。少

The very high-speed Backbone Network Service(vBNS) provided by U.S.National Science Foundation(NSF) was the first high-speed research network. Since 1998, the Abilene, which has been operating as a testbed for development of next generation Internet conducted by Internet2 project, is a focal network to integrate worldwide research activities on Internet. Similar to European countries, Japanese SINET had connected to Abilene in order to join Japanese researchers to Internet2 project from October 1999.Canadian CA^*net3, Trans-European Network(TEN-155), German DFN, French RENATER, Dutch SURFNET as well as Nordic NORDUnet, which are domestic and regional high-speed research networks, are mutually interconnected to create global infrastructure for researches. The objective of the research is to maintain and to develop global and broadband connectivity of research networks. Summary of research in 2000 are as follows.(1)Investigators made progress report and proposal at World Telecommunicatio … More n Congress, in May, Birmingham, U.K.and also contributed IPv6 Conference at the same place, in order to deploy IPv6 to worldwide research communication.(2)Investigators made presentation of traffic design for future broadband networks, where new statistical phenomena, called "self-similarity", has been a dominant item to re-consider bandwidth design.(3)Investigators attended annual member meeting of Internet2, in October, Atlanta, U.S.in order to coordinate worldwide broadband connectivity and also discuss future plan of transition to worldwide photonic research network.(4)Investigator attended annual meeting of Canadian research network, CA^*net3, in December, Montreal, in order to conduct technical discussion to establish wide-area photonic research networks including future coordination of interconnection of Asia/Pacific and Canadian photonic research networks.To conclude investigation in three years, the research has been contributing Japanese researchers and Japanese academic researches by developing networked research environment, through conducting worldwide coordination and technological development to maintain communication quality and effectiveness for researches. Simultaneously, intiation of future arrangement, that is the preparation to photonic research network, is also conducted by identifying technical development and by creation of new concept for 21^<st>century.
