JGN 11 (Japan Gigabit Network 11)

Abstract

This paper presents a overview of JGN2, Japan Gigabit Network 2, which has been established on the end of March 2004. JGN2 was built as a successor of JGN1, which has been established by Telecommunication Advancement Organization (TAO) in 1999. First, JGN2 network structure is explained. JGN2 provides gigabit level layer one, two, three functionalities to the research communities. Layer one provides optical path, layer two provides Ethernet connection, layer three provides IPv6 network respectively. JGN2 can be used not only for Japanese domestic network research but also for international network research. Network structure of Pacijc Northwest GigaPoP and Aisia PciJic POPs are described and it is shown how JGN2 is connected to other gigabit research network in worldwide. Experiments on JGN2 at international conferences are also described. High Dejnition(HD) TV transmission experiment at JGN2 symposium 2005 and VoIP connection to the Internet at APRICOT 2005 is described and examined the effectiveness of the gigabit network.
