CSE “ IV (1)1. Topic Identification:
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. We can overcome these restrictions by using the Sky X protocol.
2. Scope:
Networking over satellites is faced with overcoming the latency and high bit error rates typical of satellite communications, as well as the asymmetric bandwidth of most satellite networks. The Sky-X technology can be used to overcome these drawbacks.
The Sky-X family consists of the Sky-X Gateway, Sky-X Client/Server and the Sky-X OEM product. The Sky-X solution is entirely
transparent to end users, works with all TCP applications and does not require any modifications to end client and servers.
3. Mechanism:
The Sky-X Gateway and Sky-X Client/Servers systems replaces TCP over satellite page link with a protocol optimized for the long
latency, high loss and asymmetric 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 Gateway transparently enhances
the performance of all users on a satellite network without any modifications to the end clients and servers. The Sky-X
Client and the Sky-X Server enhance the performance of data transmissions over satellites directly to end user PC's, thereby
increasing Web performance by 3 times or more and file transfer speeds by 10 to 100 times. Sky-X products are the leading
implementation of a class of products known variously as protocol gateway TCP Performance Enhancing Proxy (TCP/PEP), or
satellite spoofer. The Sky-X gateways are available as ready to install hardware solutions which can be added to any
satellite network.
Sky-X products increase the performance of IP over satellite through a combination of protocol connection-splitting, data
compression, and Web pre-fetching, while remaining entirely transparent to end users. 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 page link which the protocol is optimized for satellite conditions.
The Sky-X gateway works by intercepting the TCP connection from the client and converting the data to the Xpress Transport
Protocol (XTP) for transmission over the satellite. The Sky-X gateway on the opposite side of the satellite page link 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. This architecture is also referred to as TCP
Performance Enhancing Proxy (TCP-PEP)
