Introduction : Satellites are an attractive option for carrying Internet

and other IP traffic to many locations across the globe where terrestrial options are limited .

The Sky X technology replaces TCP over satellite link with a protocol optimized for the high loss and bandwidth conditions of the typical satellite communication.

Adding the Sky X system to a satellite network allows users to take full advantage of the available bandwidth

The Sky X technology transparently enhances the performance of all users on a satellite network . 4

WORKING :

Sky X Technology Overcome TCP Performance Limitations.

Even though the TCP is very effective in the local network connected by using cables or optical fibers by using its many features

Thus the advantages achieved by TCP in LAN's are no longer effective in the satellite link.

So it is desirable to design a separate protocol for communication through the satellite to eliminate the disadvantages of using TCP over the sat

5

The Sky X gateway works by transparently replacing TCP connections from the client and converting the data to Xpress Transport protocol (XTP) for the hop over the satellite link .

The sky X client/server system enhances the performance of the internet and private network access over satellite links.

XTP Protocol :

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.

7

Characteristics of XTP :

Error control flow Control Prioritization Issues Multicast mode Selective Retransmission Multi-packet handshaking

8

Sky X-Gateway : The Sky X gateway works by intercepting the TCP

connection from the client and converting the data to the XTP for transmission over the satellite.

The Sky X gateway on the opposite side of the satellite link translates the data back to TCP for communication with the server.

No changes are required to the client or server and all applications continue to function without modification.

Application :

Used for Satellite communication.

Used for accessing web in fastest speed.

Used For data transfer, File Transfer efficiently.

11

Merits :

Increases web performance 3 times faster.

Does not require any modifications to end client and servers.

Sky X Gateway provides fast, efficient, fully reliable multicast file transfers.

12

Future Enhancement :

A product called XipLink which is under developing will replace the sky X.

It is very much the same as the Sky X with extra capabilities.

It optimize all TCP/IP traffic, basically the link itself.

13

Conclusion : Thus Sky -x technology is best suited

for satellite communication using XTP protocol and Sky x gateway.

The Sky X system of a satellite network allows users to take full advantage of the available bandwidth

It gives all features required for successful data Transmission.
