Challenges of Creating Global Internets - the Teledesic Example
(Hans-Werner Braun, Teledesic)
Over the last serveral years the Internet has experienced an enormous
growth in global ubiquity, implemented in a complex meshed
interconnection
across many service providers, while also experiencing significant
shifts
in workload profiles based on characteristics of new applications. In
this growing phase the systemic Internet performance is at risk. One
of the approaches to address the global "complexity diameter" is to
create satellite networks with world-wide coverage and performance
characteristics resembling conventional terrestrial connections. In
the case of Teledesic, a constellation of hundreds of Low Earth Orbit
satellites is planned to create a global high performance "Internet in
the
sky," that will enable affordable access to fiber-like
telecommunications
capability anywhere in the world. Offering this kind of global high
quality communications services presents intriguing challenges in
network
architecture and performance analysis, including in its integration into
the global Internet community.
Performance Measures for Multimedia Applications
(Randy Bloomfield,
Institute for Telecommunication
Sciences)
The Internet is rapidly evolving to support multimedia
applications. This presentation provides a high-level overview
of selected activities being undertaken by the Institute for
Telecommunication Sciences (ITS) to develop and apply novel
user-oriented, technology independent performance measures for
audio, video, data, and multimedia communications systems. The
presentation is aimed at facilitating dialogue on the role of
quality-of-service and network performance assessment
activities in support of Internet operation and evolution.
The Zebra Distributed Routing Software
(Kunihiro Ishiguro, Digital Magic Labs)
The Zebra distributed routing software represents a new approach to
managing the complexity of routing over the Internet. To be freely
distributed under the GNU General Public License, Zebra supports BGP-4,
RIP-1,2 and will support OSPFv2 and RIPng and so on. Zebra runs under
kernels with multi-threading support as well as FreeBSD, Solaris, and
Linux. Zebra's BGP daemon is currently running on the Route Server at the
NSPIXP exchange point in Japan. More information is available through the
Zebra Web site.
Open Issues Forum
This session will provide an opportunity for backbone operators, ISPs, and
other community members to present informal, 15-minute updates on Internet
operational issues. If you are interested in presenting, send e-mail with
a brief description of your topic to Susan Harris at Merit
(srh@merit.edu). We'll also solicit ideas for topics on the first day of
the meeting.
