- Measurement of Routing Switch-over Time with Redundant Link
Masaki Hirabaru <masaki@nict.go.jp>, Teruo Nakai (KDDI), Yoshitaka Hattori (KDDI), Motohiro Ishii (QIC), and Yasuichi Kitamura (NICT)

Abstract: Many international links are being coordinated to cope with outages. It is important to know how fast they can switch to another in order to evaluate and improve the quality. We report our method and results of experiments that measure switch-over time of two redundant paths; 1) Fukuoka-Tokyo over JGN II and 2) Japan-US over JGN II/TransPAC2.

- The role of Routing Registries and RPSL in AARNet3
Bruce Morgan <bruce.morgan@aarnet.edu.au>

Abstract: With increasingly complex network connectivity AARNet has implemented a policy of using Internet Routing Registries and RPSL (Routing Policy Specification Language) to describe and implement its routing policies and provide scaleable and consistent approach in creating router configurations across multiple routing platforms.

- TransPAC2 security talk abstract
Williams, James G <william@indiana.edu> and John Hicks <jhicks@iu.edu>

Abstract: Directors of National and International Research and Education Networks (REN) face security challenges not commonly seen in most corporate or government organizations, due to the existence of highly diverse technology environments and the unique cultural aspects of their mission. This talk will briefly describe the Research and Education Networking Information Sharing and Analysis Center (REN-ISAC), as well as federated security services such as federated networks, collaborative incident analysis and response, and security-aware capabilities. The main focus of this talk will describe the incorporation of TransPAC2 into the REN-ISAC monitoring, analysis, and reporting mechanisms. Future expansion of these security monitoring and analysis services will also be discussed.

- Wireless global roaming via eduroam
Chris Myers <chris.myers@aarnet.edu.au>

Abstract: EduRoam allows roving researchers to log-in, with their usual "user name/password", to wireless networks at participating campuses around the world and transparently get access to resources at their home institution. To date there are over 350 connected sites. This presentation would be on the activities of this working group. How the ASIA PACIFIC area can become involved in this project. Future directions of eduroam NG (next generation).

- Current plan for e-VLBI demonstrations at iGrid2005 and SC2005
Koyama Yasuhiro <koyama@nict.go.jp>

Abstract: An international research team for Very Long Baseline Interferometry is planning to perform e-VLBI demonstrations at iGris2005 and SC2005 meetings. At present, it is planned to perform real-time data transfer from radio telescopes at Westford (Massachusetts, USA), Westerbork (Netherlands), and at Kashima (Japan) to the correlator facility at the Haystack Observatory of MIT located at Westford (Massachusetts, USA). Since two different observing terminals will be used at the telescope sites, a proposed standard protocol for e-VLBI based on the RTP protocol is considered to be used to transfer the observed data.

- US R&E Initiatives: NLR, Abilene, HOPI and Beyond
Chris Robb <chrobb@grnoc.iu.edu>

Abstract: This talk will provide and update on the US R&E infrastructure changes over the past six months. Both the National Lambda Rail and Internet2 HOPI networks have expanded greatly in the past half year. There will be a focus on the synergies between the Asian Pacific region and these two new US research networks. The talk will also include an update on the TransPAC2 network and a discussion of how TransPAC2 can assist in bringing the two continents together in this fascinating new area of network research.

- Toward this year's high performance demonstrations
Jin Tanaka <tanaka@kddnet.ad.jp>

Abstract: There are a number of high performance demonstrations and experiments scheduled to be held at iGrid2005 and SC2005 again this year. APAN Taiwan meeting will be the best opportunity to review the lessons learned from the last year's high performance demos supports and to discuss current network configurations and systems of NOCs. This talk will focus on measures to cope with this year's demonstrations and to strengthen collaboration between network engineers and high performance end users.

- Network Monitoring System with Scheduler
Takatoshi Ikeda <tk-ikeda@kddilabs.jp>

Abstract: APAN TokyoXP NOC supports a lot of demonstrations and experiments through the year. Especially, during the Super Computing, many demos and experiments are conducted by its participants over trans-pacific circuits in a short period. From our experience of these supports, we think the schedule management for the link and monitoring the traffic along the schedule is very important. Therefore, I'm developing a network monitoring system with scheduler. In this talk, I will present about this system and do some demonstrations.

- The NLANR/MNA International AMP Mesh
Ronn Ritke <rritke@nlanr.net>

Abstract: This talk will provide an overview of the NLANR International AMP Mesh. The presentation will describe AMP, the over 2 dozen AMPs deployed overseas, the PRAGMA testbed instrumentation and the interest in local AMP meshes.

- Impact of Bottleneck Queue on Long Distant TCP Transfer
Masaki Hirabaru <masaki@nict.go.jp> and Jin Tanaka (KDDI)

Abstract: We present how a queue at a bottleneck would have impact on high-performance TCP data transfer over long distant networks. Designing high-performance, international networks require considering transport protocol behavior that could be affected by a queue of interface at a backbone switch/router.

- GrangeNet II
Greg Wickham <greg.wickham@grangenet.net>

Abstract: Due to the successes of the GrangeNet program a funding extension was granted until the end of 2006. As part of the funding extension a component was allocated for maintenance and refresh of the existing GrangeNet backbone equipment. In collaboration with Cisco an innovative network architecture was developed that permits unparalleled connectivity between researchers that have access to the existing GrangeNet POP sites. The new network supports layer 1, layer 2 and layer 3 services to the GrangeNet community.

This presentation will be used to describe the logical and architectural concepts that underpin the GrangeNet II network; provide a detailed examination of the interior workings of the new equipment; and provide examples on how researchers can best benefit from this new architecture.

- KOREN Update
Lee Jaehwa <jhlee@noc.kr.apan.net> and Heesang Park

Abstract: This presentation will be talking about a mobile IPv6 deployment over KOREN member which is another joint research project between NCA/MIC and KT. The main focus of the project is to massively test the mobile IPv6 over a real network. The project will deploy a mobile IPv6 wireless network over KAIST. In addition to this presentation will talk about some recent upgrade plan/updates of KOREN such as e2e VLAN service and PC router, and IPv6 multicast.

- Report of NICT's international collaborations
KITAMURA Yasuichi <kita@jp.apan.net>

Abstract: National Institute of Information and Communications Technology(NICT) has been working for several international collaborations. In this session, some of these activities, especially APEC-TEL matters, which were happened after APAN Bangkok meetings will be reported.

- SINET update and collaboration with TEIN2
Jun Matsukata <jm@nii.ac.jp>

Abstract: The overall topology of SINET national backbone remained unchanged though we had changes of carriers of many portions of SINET including the 10 Gbps backbone circuits by April 2005. As for the upgrade of international connectivity which took place by April 2005, an OC48 between Tokyo and Pacific Wave at LA came into operation, and the four OC48s between Tokyo and New York became a single OC192.
Now, we are planning to establish links between Tokyo and Singapore, as well as Tokyo and Hong Kong; both of them are meant for realizing an intra-Asia network in collaboration with TEIN2.

- TEIN2 collaboration
Yu-lin CHANG <ylchang@gate.sinica.edu.tw>

Abstract: Some possible ways of collaboration between the bandwidth / circuit donators and TEIN2 communities will be discussed in this presentation. First issue for RENs who contribute TEIN2 is the demarcation of responsibility. Second issue maybe the operation procedures, especially the procedure of troubleshooting. Then the big problem may be how a donator can transfer a bandwidth or a circuit to TEIN2 under the contractual restriction between him and his suppliers? Whom should the suppliers face to? How to request help from suppliers?

- TEIN2 Overview
David West <David.West@dante.org.uk>

Abstract: This talk will present the work underway to establish the TEIN2 network. The planned network topology will be shown, together with rollout plans, and including the collaborations with other networks interested in helping to establish to a strong regional research networking infrastructure.

- TEIN2 Engineering Plans
Michael Enrico <michael.enrico@dante.org.uk>

Abstract: This talk will describe work currently underway to develop technical plans forimplementing the TEIN2 network.

- Thoughts on TEIN2 Operation and Collaboration
Xing Li <xing@cernet.edu.cn>

- Abstract: TEIN2 is a very important project to link academic networks in Asia Pacific and Europe. Based on the operation experiences of DRAGONTAP, CERNET, CERNET2, NSFCNET, APAN-CN, CERNET-KOREN and CERNET-JANET etc, we will discuss the connectivity and routing management issues, including configuration, performance monitoring, problem handling, security procedure and the online access of the operation information. Under the framework of the TEIN2, we welcome suggestions and comments for the TEIN2 operation.

- APAN-TEIN2 NOC tools
Yoshitaka Hattori <hattori@noc.kddnet.ad.jp> and Jin Tanaka

Abstract: In order to achieve cooperated inter-domain network operation, APAN-JP proposes network operation with some common tools. It will not only be useful for operators' collaboration but also lead to fully utilizing the experience and know-how of APAN-JP and Global NOC. This talk will suggest some tools that should be adopted by TEIN2, based on the operation tools actually used by APAN-JP NOC. Furthermore, how we should cooperate for maintenance and management of those tools will also be discussed.

- Global Federated Network Operations Structure
Williams, James G <william@indiana.edu>

Abstract: I would like to discuss the development of a federated network operations structure to facilitate the exchange of information regarding network status and troubles between major research networks. Researchers who use this e-science infrastructure will REQUIRE this of network operators. As an example, imagine a group of researchers that requires a network connection between a computing environment in France, transiting the US and a data-store in Korea. These researchers will expect that the NOC in their home country (France in this case) will have access to all available information regarding their network connection to Korea. "The problem is not in the GノANT network" is NOT an acceptable response. Simply put, we must find productive mechanisms for NOC-NOC interaction.

Title: Application and Evolution of the DWDM Network  

Abstract:
In the past few years, there has been an enormous increase in the bandwidth requirements of broadband service networks. The DWDM network will quickly evolve from point-to-point DWDM to fixed OADM ring, ROADM ring and then to multi-degree ROADM mesh network. These networks will provide vast increases in capacity and offer multiple service transportation. They will drastically decrease the transmission cost per channel and become flexible, expandable, and highly reliable. A review of various WDM ring and mesh architectures, their evolution and application will be given. Special emphasis on ROADM application will be addressed.

Title: The Lambda Testbed of TWAREN

Abstract:
TWAREN Lambda Testbed grants the subscription of lightpath to users within Taiwan and their collaborators in the United States. For e-Science applications and collaborations, where numerous hosts and network nodes are present, the provisioning of an end-to-end lightpath is procedurally simple and best meet the requirements. In order to keep track of the lightpath layouts and residual bandwidth in the testbed, we propose an optical management plane for monitoring lambda networks. In this scheme, dynamic restoration can be achieved to ensure maximum lightpath survivability; meanwhile, the lightpath downtime can be effectively suppressed.

Title: Experience Sharing--TWAREN DWDM Testing

Abstract:
A hybrid optical network mixing DWDM and SDH is created as a testing environment using Cisco DWDM Metro Planner as the design tool. The output from the Metro Planner is used to configure the Multi-Service Transport Platform for a pair of ONS15454E's that make up the core DWDM backbone. Signals carried by wavelengths are sent to STM-64 transponders connected to routers or optical devices. In this hybrid design, both Multi-service Transport Platform and Multi-Service Provisioning Plarform are built into a single box for simplicity. The design and test results will be presented.
