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.

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.

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. |

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:
- i) requirements (e.g. software or hardware deployment)
for performing the analysis along any arbitrary path
ii) 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. |

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. |
