INTRODUCTIONSatellite 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.T he Sky X Technology is the evolution of XTP & SKY X gateway .

Why sky x Tec hnology ?Internet protocols( TCP/IP ) are not optimized forsatellite conditions so the throughput over the satellitenetworks decreases to only a fraction of availablebandwidth.Satellites are ideal for providing internet & private networkover long distance.the satellite conditions adversely interact with a number of elements of the TC P architecture, including it s windowsizing, congestion avoidance algorithms & dataacknowledgment mechanisms.

Why Sky X t ec hnology (c ontinu e s)y T he advantages achieved by TC P in LAN's are no longer
effective in the satellite link. So it was desirable to design aseparate protocol for communication through the satelliteto eliminate the disadvantages of using TC P over satellite
Thus We need sky x technology.

WORKINGSky X products do combinations of connection-splitting & data compression.
T he Sky X system delivers the Web objects to theSky X gateway on the client side of the satellite link.components:

Xpress T ransport Protocol (X T P) is a transport layerprotocol for high-speed networks promoted by the
X T
P Forum developed to replaceTC
P. X T P provides protocol options f or error control,f low control, and multicast mode . Instead of separate protocols for each type of communication,
X T
P controls packet exchange patterns to producedifferent models.

Sky X gat ew ayT he Sky X gateways works by replacing TC Pconnections from the client & converting the data to
XpressT
ransport protocol ( XTP).T ranslates the data back to TC P for communication withthe server.No changes are required to the client or server and allapplications continue to function without modification.

Sky X me ritsSky X system allows users to take f ull advantage o f theavailable bandwidth.T ransparently enhances the performance of all users on asatellite network & increases web per f ormance by 3times or more & f ile trans f er speeds by 10 to 100 times .Entirely transparent to end users , works with all TC Papplications & does not require any modi f ications toclient & servers.
Increase the performance of IP over satellite through acombination of protocol connection-splitting, datacompression.
