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.

This paper proposes a distributed and cooperative scheduling mechanism for dynamic load-balancing on a large-scale distributed computing environment. In the proposed mechanism, the scheduling processes are performed by independent distributed schedulers on individual computing resources. Decentralized mechanisms are more suitable for dynamic load-balancing of a large-scale distributed computing environment than centralized mechanisms in terms of scalability and fault tolerance. Experimental results show that the proposed scheduling mechanism has high scalability and efficiency, without any excessive concentration of processing even if the number of computing resources increases

Establishing secure channels between a pair of hosts is an attractive way when the direct exchange of important data is required. IPsec provides various security services for traffic at the IP layer so we can use it to establish secure channels between a pair of hosts. However, IPsec is difficult to use because there are many parameters to set up for secure channels, and the configuration is complicated, hence our previous proposal of an automatic configuration method to set up the end-to-end secure channels between a pair of hosts; facilitating the use of IPsec. In this paper, we overview our proposed method and describe its implementation and evaluation. In addition, we show how the IPsec setup for 10 hosts on a host implementing our method is completed within a few seconds or so

During the course to deploy IPv6, we found several critical implementation and operational issues which distract user and possibly prevent wider deployment of IPv6. Among the problems we noticed, domain name system (DNS) related issues are significant. Some of the problems cause longer delay during the process to make a connection to a given node. In worst case, the delay is 60 seconds or more. This amount of delay may mislead users for some idea that IPv6 is not good technology, which is not accurate. In this paper, we reveal six cases related to DNS server and resolver implementation we found during our study in detail. To overcome these problem, fix to the servers are essential. To know how these cases affect overall behavior of the DNS, we created a tool to find misbehaving servers. We applied this tool to servers in ".JP" domain and found that there are 0.11% of servers in ".JP" domain have some problem. The other way to solve or ease the problem is to find workaround in client side. We propose two workarounds, with a sample implementation

In this paper, we propose a streaming platform which we call the STARCast. This platform enables to provide streaming service by overcoming some of the limitations and complexities of current network environments. The STARCast node consists of two types of independent data plane, the one is streaming control plane, which manages some information for connection by the resource manager, the another is streaming data plane, which enables to transfer the all kinds of streaming data without relation of their kinds, and distribute it efficiency use of ALM (application layer multicast) which can be adapted the topology for the number of nodes and requirement from user application. The STARCast also enables adaptation to various types of address spaces such as those of NAT and IPv6, and various transport networks so that streaming services can be offered anywhere on the Internet. And this proposed platform enables to provide and receive the streaming service all over the Internet using any computers ubiquitously. As an function of the STARCast for streaming, we discuss the method for application layer multicast which enables to adapt node character and environment. In this paper, we show the its availability by the simulation.
