| Hi,
|
| The major issues in providing this has been asymmetry and high latency,

I cannot shed any light on this except to forward a press release that says
that StarBurst and Teleglobe will be using multicast for web warehouse push
via satellite multicast using Intelsat:
INET '98: Teleglobe, Intelsat Team on Satellite System for Internet
Global satellites will push Web content to Internet service providers in
far-off lands, making access cheaper.

GENEVA -- Canadian Telecommunications provider Teleglobe has teamed up with
satellite operator Intelsat to jointly beta test a multicasting and
replication system that aims to push selected Internet content to multiple
sites around the world over a satellite network, the companies announced
here Wednesday.
The idea is to push frequently accessed Internet content to servers around
the world so that users don't need to pull data from sites off the Internet
in far-away countries, the companies said. The multicasting software system
was developed by Maryland-based A&T Systems.
During the first phase of the trial, which will begin in November,
Teleglobe will cache preselected popular content, as well as content
requested by the kiosk operators, the company said. Teleglobe will also
strike deals with content providers who wish to offer their material on the
push system. In this phase, the content will be pulled to a "warehouse" on
the Intelsat base station. However, in the future, the warehouse itself
will be able to receive pushed content, including music, sports events, and
real-time news.
Teleglobe plans to offer the service commercially by mid-1999, the company
said. While it won't be solely aimed at Internet service providers in
developing countries, that is where the demand will be greatest for
satellite-based content provision, according to the company. Four ISPs will
be involved in the test: South Africa Telecom, Cyprus Telecom, IDSC Telecom
in Egypt, and Embratel in Brazil.
The satellite-based Internet service replaces a leased-line situation in
which an ISP would need to have a constant connection to the Internet,
Teleglobe said. Since it is very expensive to lease lines in developing
countries, a satellite setup allows ISPs to save money and pass along these
savings to their customers, Teleglobe said. With content cached locally in
the country, users won't have to go out onto the Web and pull information
from servers located across the world, which saves time and reduces network
traffic, the companies said.
Teleglobe offers services to telecom providers and ISPs around the world
via its network of 41 earth stations and undersea cables.
