Introduction

3. Introduction
 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 .
 The Sky X increases web
performance by 3 times or more and
file transfer speeds by 10 to 100
times.

4. Why Sky X-Technology???
 Satellites are ideal for providing internet
and private network access over long
distance and to remote locations.
 However the internet protocols are not
optimized for satellite conditions and
consequently the throughput over the
satellite networks is restricted to only a
fraction of available bandwidth.
 Thus We need sky x technology to over
come these restrictions and to access
maximum bandwidth.

5. 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 XRP instead of 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.

6. Sky X Gateway Splits
the TCP into three
Components:
1. TCP connection
Between the Client and
Sky X gateway.
2. An XTP connection
Involves Sky X protocol
over the Satellites
between the two Sky X
Gateways.
3. TCP connection between
opposite Sky X Gateway and
Server.
XTP is transport layer protocol design to operate over high speed network
and provides high level performance to the End-Users.

7. Sky X Gateway Network Integration

8. 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 flow control, and multicast
mode.
 Instead of separate protocols for each type of communication,
XTP controls packet exchange patterns to produce different
models.

9. Applications
 The Sky X gateway combines protocol, application and system level
enhancements to provide maximum throughput for satellite networks.
 The Sky X Protocol utilizes a highly efficient selective retransmission
algorithm for the acknowledgment of data. Because there is only a single
path over the satellite with no intermediate routing.
 Sky X products include HTTP specific optimizations to further accelerate
web downloads.

10. 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.

11. Conclusion
 Thus Sky -x technology is best suited for 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.
