The Sky X technology uses Sky X gateways and the XTP protocol to improve bandwidth utilization over satellite networks. The Sky X gateway intercepts TCP connections and converts data to XTP for transmission over the satellite link. It then converts data back to TCP for delivery. This architecture enhances performance without any changes to end clients or servers. Using XTP and optimizations, Sky X can increase web and file transfer speeds by 3-100 times over standard satellite internet connections. It provides a fully transparent and reliable way to access more of the available satellite bandwidth.

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.
