Studies on International Collaboration for Research Networking and International Coordination of Asia-Pacific Coutries

近年来，不仅在发达国家，而且在新兴发展中国家和地区，包括中东欧、中南美洲、非洲和亚洲国家，研究网络呈现出极其多样化的趋势。因此，研究网络之间的国际协调对于建立国际交流联系具有重要意义。洲际研究网络协调委员会（CCIRN）在这种协调中起着主要作用。此外，还强调了对宽带通信链路的需求，以促进更高端的研究。在这种背景下，CCIRN正在讨论如何将这种宽带通信链路和网络互连起来。美国在伊利诺伊州芝加哥推出了新的宽带网络互连点，称为STAR-TAP（科学，技术和研究，过境接入点）。参与研究的研究人员在三年的时间里进行了国际合作活动，最终于1997年10月成功地将日本海外网络（SINET）与STAR-TAP连接起来。欧共体也投入了宽带研究网络（TEM-34）的运行。SINET已经与欧洲研究网络合作了三年，因此SINET将其连接点改为英国伦敦的TEM-34 PoP （point of Presence）。开往伦敦的航线将于1998年4月初开始运营。这是该研究的第二个结果。除了实际的互连之外，研究人员还在IETF对基于ATM的网络进行国际标准化。在此基础上提出了ATM地址解析方案、ATM连接控制信息和高性能协议规范等方案，目前已形成Internet草案。这些活动被评价为今后研究网络国际联系的基础。

In recent years, research networks have extremely diversified, not only in developed coutries but also in newly developing contries and region, including mid and east europe, mid and south america, africa and asian coutries. As the result, international coordination among research networks is of important to establish international communication links. The CCIRN (Coordination Committee for Intercontinental Research Networks) plays primary role of such coordination. In addition to this, need for braodband communiation links is emphasized in order ato stimulate higher end researches. In this context, the CCIRN is now discussing how to interwork such broadband communication links and networks.United States had lauched new interconnecting point among broadband networks in Chikago, IL., which is called STAR-TAP (Science, Technology and Research, Transit Access Point). Investigators joined to the study have made international cooperation activities during three years, and finally made success to interconnected japanese boradbnad network (SINET) to STAR-TAP in October, 1997.European Commuinity has also put in operation of braodband research network (TEM-34). SINET has been cooperating to european resarch networks for three years, and consequently SINET has changed its connection point to TEM-34 PoP (Point of Presence) to London, UK.Circuit to London will be in operation from early April, 1998. That is second result of the study.Beside the actual interconnection, investigators have been contributing international standardization at IETF on ATM based networking. Several proposals which are now available as Internet Drafts, including ATM address resolution scheme, ATM inteconnection control information and high-performance protocol sepcifications, are proposed from the study.These activities are evaluated as future basis for international connection of research networks.
