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.
