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
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
Sky X Gateway
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 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 which is the protocol optimized for satellite conditions.
Sky X Multicast Fan-Out
Computer networking traditionally relies on unicast data transfers which establish point-to-point connections between devices.
In situations where the same data is transferred to multiple users, the server must send a copy of the file to each recipient independently. This process is both time consuming and wastes much of the bandwidth resources.
In contrast, multicast technology makes it possible for multiple recipients to receive a single data stream.
The Sky X multicast fanout, an integral component of the Sky X gateway, transparently converts TCP unicast connections into reliable multicast transfers.
