INTRODUCTION

• Satellite are an attractive option for carrying
  Internet other IP traffic across the globe. But
  the internet protocol which we use on land are
  not optimized for satellite.
• The Sky X Technology is the evolution of XTP
  SKY X gateway .

Why sky x Technology ?

• Internet protocols(TCP/IP) are not optimized for
  satellite conditions so the throughput over the
  satellite networks decreases to only a fraction
  of available bandwidth.
• Satellites are ideal for providing internet
  private network over long distance.
• the satellite conditions adversely interact with
  a number of elements of the TCP architecture,
  including its window sizing, congestion
  avoidance algorithms data acknowledgment
  mechanisms.

5
Why Sky X technology (continues)

• Thus the advantages achieved by TCP in LAN's are
  no longer effective in the satellite link. So it
  was desirable to design a separate protocol for
  communication through the satellite to eliminate
  the disadvantages of using TCP over satellite
• Thus We need sky x technology.

6
WORKING

• Sky X products do combinations of
  connection-splitting data compression.
• The Sky X system delivers 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.
• components
• 1. XTP
  2. X-Gateway

• Xpress Transport Protocol (XTP) is a transport
  layer protocol for high-speed networks promoted
  by the XTP Forum developed to replace TCP.
• XTP provides protocol options for error control,
  flow control, and multicast mode. Instead of
  separate protocols for each type of
  communication, XTP controls packet exchange
  patterns to produce different models.

8
Characteristics of XTP

• Error control
• Flow control
• Byte ordering
• Multicast mode
• Multi packet handshaking

Sky X gateway

• The Sky X gateways works by replacing TCP
  connections from the client converting the data
  to Xpress Transport protocol (XTP).
• Translates the data back to TCP for communication
  with the server. This architecture offers vastly
  improved performance while remaining entirely
  transparent to the end user and fully compactable
  with the internet infrastructure.
• No changes are required to the client or server
  and all applications continue to function without
  modification.

Sky X merits

• Sky X system allows users to take full advantage
  of the available bandwidth.
• Transparently enhances the performance of all
  users on a satellite network increases web
  performance by 3 times or more file transfer
  speeds by 10 to 100 times.
• Entirely transparent to end users, works with
  all TCP applications 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.

11
Future Enhancement

• XipLink developed by 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

12
Conclusion

• Developed just to solve the problems faced by
  TCP/IP in satellite communication but its
  enhanced form that is XipLink will be the need in
  concepts of information super highway smarter
  planet like things.
