CRNET - Costa Rica Interconnection of the Grand Caribbean Region to Advanced Research Networks Luis Diego Espinoza
  The National Research Network of Costa Rica, CRNet, jointly with the University of Costa Rica, UCR, introduced large scale internetworking in the country. In collaboration with the Organization of American States Project, RedHUCyT, and Universities in the Central American and Caribbean Region, CRNet has played a crucial role for the region's pioneer interconnection to the Internet and the establishment of Research and Academic Networks in the area during the last decade. CRNet's backbone provided access to almost all academic and government institutions prior to the PTT's emergence into commercial services. It has also provided continuous support, knowledge and experience to almost all sectors. CRNet engineers contributed with the design and implementation of the Advanced Internet Network (RIA), a joint project of the Ministry of Science and Technology, MICIT, and the Instituto Costarricense de Electricidad (ICE) to provide broadband connectivity. The first phase of the project was successfully implemented with the installation of a DWDM ring in the metropolitan area and xDSL access. The second phase of this project will bring broadband Internet connectivity all across the country with the installation of 100 000 xDSL lines and a strong IP Core Network based on Gigarouters with an aggregated bandwidth of 30Gbps, using 5200 km of fiber. The advanced network will also carry high bandwidth academic and research Internet 2 traffic under CRNet, which will enter a new phase as CR2Net. CR2Net will be the coordinating entity for advanced research and academic networking applications in the country. CR2Net is a joint initiative of the Center for Advanced Technologies (CENAT), the Ministry of Science and Technology and the National Academy of Sciences of Costa Rica. CR2Net has started with seven institutions. The access is provided by a VPN over MPLS to a local Internet2 (inter-institution) access. We are considering the Global Terabyte Research Network (GTRN) initiative to provide high capacity global connectivity, as well as connectivity within the region, instead of a model based on independent dedicated links for each country. This has the advantage of providing high capacity and cost sharing, allowing lower prices. It is expected that the Grand Caribbean Region GNAP (Global Network Access Point) will use the Americas Region Caribbean Optical-Ring System (ARCOS). ARCOS, is a high capacity ring (up to one Tbps) that interconnects 15 countries, linking the U.S., Mexico, Guatemala, Belize, Honduras, Nicaragua, Costa Rica, Panama, Colombia, Venezuela in the continent to the Bahamas, Turks & Caicos, Dominican Republic, Puerto Rico, and Curacao in the Caribbean. ARCOS ring topology provides the required infrastructure to establish the Grand Caribbean Region GNAP. It is expected that this GNAP will be interconnected to similar GNAP's in South America and elsewhere in the future, according to the GTRN connectivity model, to provide the capabilities needed to increase worldwide connectivity for scientific and academic networks.
Foundry Networks MIS and IT Managers Can´t Manage What They Can´t Measure or See Val Olivia
  MIS and IT managers can´t manage what they can´t measure or see. There are many applications that measure and verify the performance and function of servers and storage. Until now, there has not been an efficient way to understand what is happening in the network that connects the servers and storage. Why is the Internet slow? How many servers do I need and where do I need them? How much bandwidth do I need for backup of storage? Is my ISP charging me correctly? Are my network security policies implemented properly and are they effective? By embedding sFlow (RFC3176) into the ASIC hardware of networking switches, Foundry Networks has made it possible to build business intelligence from the network without impacting network performance, from network speeds as low as 10 Mbps to as high as 10 Gbps and beyond. With convergence (voice, video, and data) and the requirement for high speed computing, MIS and IT managers can now easily see these applications at work, on a real-time basis or a cumulative historical basis. Managers can spot application trends, and identify application transactions flowing through the network. In addition, this capability enables continuous and always-on surveillance that can identify disruption or intrusion in the network.  
Greek Research and Technology Network An Inter and Intradomain Qos Provisioning Architecture Dimitrios Kalogeras
  Although QoS is considered as an essential property of the future IP networks, and despite the effort towards this direction by researchers, standardization organisations, vendors and network managers, only a few networks exist today that can provide end-to-end QoS for a wide range of applications to its clients. Serious practical deployment issues and lack of know-how usually confine provisioning within the domain and to specific applications. This paper outlines an architecture for inter- and intra-domain end-to-end QoS provisioning and presents our experiences from deploying this architecture.  
Greek Research and Technology Network GRNET2 Implementation Update Tziouvaras Chrysostomos
  The poster will present the current status and future plans for the implementation of GRNET2, a gigabit network based on state-of-the art DWDM technology. It will also present the new platform of services that will be provided to the community of GRNET users, that are enabled by the adoption of the gigabit infrastructure.

jaalaM Technologies ANA: An Effective Approach to a Distributed, Cooperative End-to-End Network Measurement and Analysis System
Loki Jorgenson

End-to-end network analysis offers a unique viewpoint that complements other measurement and diagnosis techniques. Its practical value is determined by at least two critical factors:

  1. requirements (e.g. software or hardware deployment) for performing the analysis along any arbitrary path
  2. ease of use, flexibility, and pervasiveness of that requisite infrastructure

Reducing the limits imposed by both factors makes for an effective end-to-end system. The ANA network analysis system approaches these issues by employing active probing techniques that require no end-points and by supporting broad distribution of its from-points and user interfaces; the coodination of tests, analyses, and analysis archiving is performed at a central node. The system is constructed to encourage participation, sharing and cooperative use of common resources (from-points and analysis results) through ease of deployment, access, and use. To date, several network experiments between geographically disparate groups have been performed that would have otherwise have been difficult to execute. Details of the ANA system, end-to-end analysis technology, and experimental results are presented.

Radvisions Videoconferencing for Education --A Case Study Michael Coniaris
  The State of Alaska has the most rural and isolated schools in the United States. Providing educational services to these remote regions is extremely challenging. In order to provide better classroom experiences, training for educators and communications for administrators, The State initiated a program to deploy a videoconferencing network to 82 schools in 7 Alaskan school districts. The program was designed to facilitate distance learning and communication in the region as well as provide connectivity to additional educational resources around the world. The network provided students and faculty alike an opportunity to meet, talk, teach, exchange ideas and learn across vast distances as well as access advanced placement programs, special education, tutoring and professional development resources. The State of Alaska turned to GCI Telecom, a leading telecommunications carrier in Alaska, and a partner of York Telecom, experts in deploying videoconferencing networks, for advice, installation and deployment and management services for the network. Over 90 videoconferencing endpoints were to be deployed in the designated schools and in a command center for the administration of the network. RADVISION's viaIP 400 solution was chosen to provide the essential multipoint conferencing, gateway, and network management services for the backbone of the network. David Sokolic of RADVISION will discuss the benefits of videoconferencing for education in Alaska, as well as the technology involved.  
SingAREN - Singapore SingAREN Optical Network & IPv6 Project Sherrie Shiong
  The Kent Ridge Advanced Network (KRAN) project is an 18-month project commencing 1 March 2002 and managed by the Singapore Advanced Research and Education Network (SingAREN) to investigate newly emerging optical networking technologies, including Gigabit Ethernet (GE), Packet over SDH/SONET (POS) and Resilient Packet Ring (RPR). The purpose is to compare the three networking technologies against performance indicators to identify the most suitable technology for different environments. This project is defined in 2 stages. The first stage involves networking testing and the second stage involves application testing.

On 13 May 2002, both Cisco Systems (USA) Pte Ltd. and SCS Networks Pte Ltd. were selected to participate in a collaboration to construct an optical test bed that could evaluate the three technologies in greater depth. The key components of the test bed involves Cisco 10720 Internet Routers, Cisco ONS15194 IP Traffic Concentrator, Cisco 7206VXR Edge Routers, Cisco Catalyst 3550 switches and even relevant optical fiber drums for distance testing. The test bed has been implemented within the National University of Singapore (NUS) campus across three major locations. As a result, relevant research institutions, such as Laboratories for Information Technology (LIT) and School of Computing (SOC) were also invited as project partners. The time schedule for stage 1 experimentation commenced on 18 July 2002 and is expected to complete by 1 March 2003. During stage 1, the optical technologies would be tested against basic indicators such as throughput, latency, latency deviation, loss, and their support for features such as Quality-of-Service (QoS), Multi-Protocol Labeled Switching (MPLS), fault recovery times, Multicasting, etc. The following 5 months until 31 August 2003 will be allocated to further experiments for stage 2. Application level testings (e.g. GRID), such as high speed large file transfers, distributed computing and other related topics will be of interest during this second stage. The poster session for KRAN will therefore share with the interested public, the results of the experiments conducted so far on the network test bed.

Deployment of IPv6 Infrastructure and Services

SingAREN provides IPv6 transit service to the research and education (R&E) community in Singapore. It is connected to the Abilene network and 6TAP in US, 6NGIX in Korea and other oversea sites. Locally, a few R&E institutes are connected to SingAREN IPv6 router via 6over4 tunnels.This project serves to spearhead the deployment of IPv6 technologies and to extend the IPv6 service to domestic R&E entities and industry partners in Singapore. Furthermore, we hope to gain IPv6 deployment experience by deploying a set of IPv6 infrastructure and services, and to develop an IPv6 deployment model for both campus network and service provider in Singapore. Starting in July 2002, this 4-month project involves the deployment of an IPv6 exchange point to provide IPv6 internet connectivity to the domestic R&E community in Singapore, and also to domestic industry partners who wish to experiment with IPv6. SingAREN will allocate global IPv6 addresses to participating partners. Members can participate and contribute to the development, deployment and testing of IPv6 technologies and solutions. In addition, an IPv6 testbed, connecting to both IPv4 and IPv6 Internet, will also be set up. Various internet services like WWW, DNS, FTP, mail and proxy service will also be set up on the IPv6 network to serve the IPv6 community. In the later stage, a suitable transition service will be set up to extend the IPv6 service to the campus network within National University of Singapore. As on 5 September 2002, a core switch has been deployed to function as the IPv6 exchange point. In addition, the IPv6 testbed with both Linux-based hosts and Microsoft Window-based hosts has also been set up. At the same time, a DNS server is functioning to provide name resolution for both IPv4 and IPv6 name records. The current work includes the setting up of an IPv4-IPv6 transition service on a Linux machine running NAT-PT. Further tasks will involve the investigation of running other services over IPv6.
