3. INTRODUCTION
• SkyX is a new technology whichovercome some restrictionin the
networks.
 Satellites are ideal for providing internetand privatenetworkaccessover
long distance and to remote locations.
 However the internet protocolsare not optimized for satelliteconditions
and consequently the throughput over the satellite networks is restricted
to only a fractionof available bandwidth. We can over come these
restrictions by using the SkyX protocol

4.  Adding the Sky X systemto a satellite networkallows users to take full
advantage of the availablebandwidth.
 The SkyX Gateway transparently enhances the performance of all users
on a satellite networkwithout any modifications to theend clients and
servers.
 The SkyX Client and the SkyX Server enhance theperformance of data
transmissions over satellites directlyto end userPC's, thereby
increasing Web performance by 3 times or more and file transfer speeds
by 10 to 100 times.

5. Why sky x Technology ?
 Internet protocols(TCP/IP) are not optimizedfor satellite conditions so
the throughput over the satellite networks decreases to only a fraction of
availablebandwidth.
Satellites are ideal for providing internet& privatenetwork over long
distance.
the satellite conditions adversely interact with a number of elements of
the TCP architecture, including it’s windowsizing, congestion avoidance
algorithms & data acknowledgmentmechanisms.

6. Why Sky X technology (continues)
 Thus the advantages achieved by TCP in LAN's are no longer
effective in the satellite link. So it wasdesirableto design a
separate protocol for communication throughthe satellite to
eliminate the disadvantages of using TCP oversatellite
Thus We need sky x technology.

7. Sky X Client/Server
 The Sky X Client / Server increases the throughput and efficiency
of network access over satellites by transparently replacing TCP
withthe Xpress Transport Protocol (XTP) for the satellite
segment of the connection.
 The sky X client/server systemenhances the performance of the
internet and private network access over satellitelinks.

8. Sky X Client / Sky X Server
Operation
 The Sky X Client, installed on Microsoft Windows-based
computers, transparently intercepts TCP connections from
applications running on the PC and transmits the data over the
satellite link using XTP.
 Sky X Server, installedat the hub of the satellite network,
establishes a newTCP connection for communication withany
device on the local network or over the Internet.

9. continue…..
 The Sky X Gateway intercepts TCP connections fromthe sender
and converts the data to the Sky X Protocol for transmission
over the satellite.
 The Sky X Gateway on the opposite side of the satellitelink
translates the data back to TCP for communication withthe
receivers.

11. WORKING
Sky X productsdo combinations of connection-splitting & data
compression.
The Sky X systemdelivers the Web objects to the Sky X gateway
on the client side of the satellite link where they can be served
locally when requested by the browser, avoiding the satellite
delay.

12. Xpress Transport Protocol (XTP) is a transport layer
protocol for high-speednetworks promotedby the XTP
Forumdevelopedto replace TCP.
 XTP provides protocol options for error control, flow
control, and multicast mode. Insteadof separate
protocols for each type of communication, XTP controls
packet exchange patterns to produce different models.

13. Characteristics of XTP
Error control
Flow control
Byte ordering
Multicast mode
Multi packet handshaking

14. Sky X gateway
The Sky X gateways works by replacingTCP connections from
the client & converting the data to Xpress Transport protocol
(XTP).
Translates the data back to TCP for communication withthe
server. This architecture offers vastlyimproved performance
while remaining entirely transparent to the end user and fully
compactablewiththe internet infrastructure.
No changes are required to the client or server and all
applications continue to function without modification.

15. Sky X merits
SkyX systemallows users to take full advantageof the available
bandwidth.
Transparently enhances the performance of all users on a satellite
network & increases web performanceby 3 times or more & file transfer
speeds by 10 to 100 times.
 Entirelytransparentto end users, works withall TCPapplications & does
not require any modifications to end client & servers.
Increase the performance of IP over satellite through a combination of
protocol connection-splitting, data compression.

16. Future Enhancement
XipLink developedby xiplink incorporation which is
under development will enhance the Sky X more.
The sky x technology is capable of handling bulk of
data which will be there in future as we are now talking
about
1. Smarter planet.
2.Infomation super highway

17. Conclusion
Developed just to solve the problems faced by
TCP/IP in satellite communication but it’s
enhanced form that is XipLink will be the need in
concepts of information super highway & smarter
planet like things.
