11. CEOS Support for IUG 2003, Sapporo, Japan May 2002 HPREN Status, CEOS NS May 2002 The Technology/Telecom Slump Global Crossing gone and other IRCs in danger. Do not know how this will affect AMPATH or other transoceanic connections Fiber switching, advanced routing, Wide/Metro area Ethernet companies all go into bankruptcy. Many established companies in trouble or pulling back

CEOS Support for IUG 2003, Sapporo, Japan May 2002 HPREN Status, CEOS NS May 2002 Africa Bleak Outlook UNEP satellite based network decommissioned this year National Library of Medicine network being redesigned Uninet, the South African network has no external connectivity The UN is going to hold sessions concerning the lack of Internet resources in Africa

21. CEOS Support for IUG 2003, Sapporo, Japan May 2002 HPREN Status, CEOS NS May 2002 Conclusion High-speed connections are here. Applications and protocols may not be ready for them. TCP performance is limited on single flows. The current economic downturn could have a negative impact in the next period. New technologies may not emerge as fast as they have in the past. The problem of the “have not” areas must be addressed.
