Next Generation Internet
Program
-- NGI --
President Clinton - October 1996
“Connect
universities and national labs with
high-speed networks that are 100 - 1000 times
faster than today's Internet. These networks
will connect at least 100 universities and
national labs at speeds that are 100 times
faster than today's Internet, and a smaller
number of institutions at speeds that are 1,000
times faster. These networks will eventually be
able to transmit the contents of the entire
Encyclopedia Britannica in under a second.”

Goal 1: Research
Coordinated,
multi-agency development,
deployment, and demonstration of the
technologies necessary to permit the
effective, robust, and secure management,
provisioning, and end-to-end delivery of
differentiated service classes
These activities cluster into three major tasks:
– Network Growth Engineering
– End-to-End Quality of Service (QoS)
– Security
Goal 2: Network Testbeds
Create and deploy tools and algorithms for planning
and operations that guarantee predictable end-toend performance at scales and complexities of 100
to 1000 times those of the current Internet
Facilitate management of large scale inter-networks
operating at gigabit to terabit speeds supporting a
range of traffic classes on a shared infrastructure
Create a network testbed of at least 100 institutions
through which users (government and research)
share facilities, thereby accelerating the
development and penetration of novel network
applications
Goal 3: Applications
Applications
should need NGI speed
or services, i.e., be something that
could not be done before NGI
Applications
should have high visibility

A Partnership
NGI and Internet 2:
Complementary and Interdependent
The Next Generation Internet (NGI) initiative is a multiagency Federal research and development program
that is developing advanced networking technologies,
developing revolutionary applications that require
advanced networking, and demonstrating these
capabilities on testbeds that are 100 to 1,000 times
faster end-to-end than today’s Internet.
Internet2 is a collaborative effort by more than 120 U.S.
universities, working with partners in industry and
government, to develop advanced Internet technologies
and applications to support the research and education
missions of higher education. Internet2 is a project of
the University Corporation for Advanced Internet
Development (UCAID).
NGI and Internet 2:
Complementary and Interdependent
The National Science Foundation (NSF) has made more than 70
High Performance Connections awards to Internet2 universities.
These merit-based awards are for connecting to NSF’s very high
performance Backbone Network Service (vBNS). vBNS
connectivity is a key part of NSF’s NGI program.
Internet2 universities are establishing GigaPoPs (Gigabit per
second Points of Presence) that provide regional connectivity
among universities and other organizations. Through the
GigaPoPs, universities will connect to NGI networks and other
advanced Federal networks, including the vBNS, NASA’s Research
and Education Network (NREN), DoD’s Defense Research and
Education Network (DREN), and the Department of Energy’s Energy
Sciences network (ESnet).
Researchers at Internet2 universities are developing a wide range
of applications that require advanced networking. Many of these
applications are funded by Federal initiatives including the NGI.

federal networks/agencies mainly for
technical exchange and coordination

of JETnets in support of end-to-end

Advanced Services
IP multicast: all JETnets (except NISN) have
native multicast running in production mode
using the PIM-SM, MBGP and MSDP protocols -1999 is the year native multicast became real in
the backbones (still not on many campuses)
IP QoS: Abilene, ESnet, NREN and vBNS are
active members of the QBone project (interdomain diffserv); vBNS has offered “reserved
b/w” service using RSVP/ATM
IPv6: all JETnets are part of the 6Bone project
and vBNS is testing a native IPv6 service
(separate routers)
Performance Expectation and Issues
For OC3 or higher connected sites with 100Mbps
switched campus nets and fine tuned end
systems (and no firewall in the path) you can
expect 80 Mbps end-to-end (memory to memory)
- this is not the TYPICAL case
Most performance bottlenecks are in the end
systems: lack of path MTU discovery, TCP
implementation, multiple memory copying and
buffer management; there are also problems in
local networks (under-power routers)
NGI program first phase mostly focused on wide
area nets, now we are focusing on local nets and
end systems
Interconnect Issues
NGIX effort: NGI / Internet2 JET
– Chicago: OC-3 going to OC-12
– Ames: OC-12
– Washington: OC-12 as soon as possible
International: StarTap plus
– Emphasize StarTap as the universal
solution
– Optimize where appropriate
– Canada as an important special case
Healthcare and the Next Generation Internet
The National Library of Medicine (NLM) is funding test-bed
projects to demonstrate the use of NGI capabilities by the health
community. These capabilities include:
Quality of Service
Security and medical data privacy
Nomadic computing
Network management
Infrastructure technology as a means for collaboration
The demonstrations are designed to improve our understanding
of the impact of NGI capabilities on the nation’s healthcare, health
education, and health research systems in such areas as cost,
quality, usability, efficacy and security.
