| It starts with a single mouse click. A few characters
of web address generates thousands to hundreds of thousands of bits of data, including
text, pictures, video, and sound. Multiply by hundreds and thousands of users to end up
with a red-hot Internet connection swamped with redundant copies of web pages. Stand-alone
caching offers some relief, but SkyCache provides room to breath.
SkyCache Release 1.0 is an affordable monthly service providing cache turbocharging and
a full Usenet News feed through high-speed satellite datacasting, constantly updating your
open-standards cache with the most popularly accessed web traffic through a combination of
Reactive Caching and prepopulation. Built on scalable technology and open standards,
SkyCache provides a superior solution to a stand-alone cache and offers a clean growth
path for other datacasting services, such as streaming audio and video.
Maximize Current Bandwidth
With better cache hit rates reducing
load on existing circuits, you can add more users and/or leased lines to your existing
business before having to buy another T1 or T3. SkyCache has demonstrated improved cache
hit rates anywhere from 10 to 40 points on top of normal hit rates. For example, if you
get a 19% cache hit rate, SkyCache could lift that hit rate to a range of 30% to 60%. In
addition, a full Usenet News feed delivered by the same datacasting technology provides
additional bandwidth conservation.
Frequently accessed web pages are
delivered directly to the cache via satellite broadcast before customers request them,
enabling them to get content at LAN speeds rather than facing delays at an overtaxed web
server, at a congested NAP, or at another bottleneck. SkyCache uses a combination of its
patent-pending Reactive Caching technology and pre-population to deliver superior update
performance in real time over static update schemes.
Cleaner Pipes = More Dollars per
Megabyte
The combination of SkyCache Release 1.0 and
an open-standards cache results in lots more breathing room, with the potential for
anywhere from a 30-50% reduction in current bandwidth utilization. This allows you to add
on more users to your current Internet connectivity. It means happier users since the most
frequently accessed web pages are locally stored for faster access.
Reactive Caching: High Speed
A cache is only as good as the number of people that
access it. As a general rule, the more people that are involved in using a cache, the
higher the hit rate on the cache. SkyCache’s Reactive Caching technology merges
statistics from all its customers to build a superior cache community and cache statistics
greater than any individual customer cache could on its own.
Reactive Caching, by virtue of working in real time
with data collected across the Internet, immediately responds to sudden bursts in web
trans-action activity and almost immediately delivers "hot" web pages caused by
unexpected rushes to web sites. One of Reactive Caching’s first successes was
catching the surge for Apple’s iMac announcement.
Satellite Broadcast = Low Drag
Having a large cache community is only a part of the
solution. Each individual cache must be quickly updated. Satellite broadcast provides a
one-way high-speed pipe to update every cache immediately and simultaneously without
expensive Internet engineering. Keeping the traffic off the Net helps speed up the Net and
your connection to the Net.
Cost Effective and Friendly
Release 1.0 is an affordable monthly
service, designed to fit into the cash flow of ISPs. Cache solutions from CacheFlow, Cisco
Systems, Cobalt Networks, Entera, InfoLibria, Inktomi, Network Appliance, Novell, and Rave
Systems have been tested and certified as SkyCache Compatible, with many others to be
tested in the future. In addition, NLANR Squid has also been certified as SkyCache
Compatible. Other solutions are frequently being sent to us for testing; call for the
latest.
Growth
for the Future
SkyCache’s high-speed multi-megabit satellite datacasting technology provides a
means of distribution for any sort of data, including software, databases, audio, and
video. Bandwidth-intensive content such as streaming media and push channels are
especially suited for transmission through future versions of SkyCache.
