Connections from applications running on the PC are intercepted and sent over the satellite using Sky X protocol. Sky X gateway can also simulate link speed bit error rate and delay conditions of the existing system on the sky X gateway test network. Fast Start Web Acceleration. The large Sky X Protocol window removes the dependency of the network on the bandwidth -delay product, allowing high throughput independent of the TCP window size of the end nodes. TCP is designed for efficiency and high performance ,and optimized for maximum throughput and the highest transaction speeds in local networks. Increase link utilization on fat WAN links. SkyX Accelerator technology overcomes latency effect on TCP over high-bandwidth links by using bandwidth much more efficiently and improving replication performance over high capacity data center-to-data center links.
This architecture offers vastly improved performance while remaining entirely transparent to the end user and fully compactable with the internet infrastructure. In contrast, TCP sends a constant stream of acknowledgments over the reverse channel. Monitor response time for each application. So it is desirable to design a separate protocol for communication through the satellite to eliminate the disadvantages of using TCP over the satellite link. Combinations of the criteria are supported, enabling more targeted monitoring and control.
XTP is a reliable, transport- layer protocol specifically designed to operate efficiently over high- speed networks and offers a level of performance not possible with TCP on long latency, high loss satellite links.
Also use at both sides of the link in a point-to-link as well technklogy in fully meshed networks.

Forward-looking statements involve risks and uncertainties, which could cause actual results to differ materially from those projected. As the graph on the left illustrates, even on server operating systems using a 32 KB window, TCP is only able to reach a through-put of Kbps. Adding the Sky X system to a satellite network allows users to take full advantage of the available bandwidth.
Because the Sky X Protocol does not use acknowledgments as the primary means of identifying lost datait requires only infrequent acknowledgments to confirm data arrival and clear buffers. The Sky X system replaces TCP over satellite link with a protocol optimized for the long latency, high loss and asymmetric bandwidth conditions of the typical satellite communication.

Replication sessions complete up to times faster and are not subject to the stalls and session drops associated with packet loss. The high end SkyX Techhnology is also a 1U rack mountable appliance capable of supporting up to 80, concurrent sessions and accepts 45 Mbps of inbound traffic for compression. The sender does not assume that any data is lost or corrupted until a multiple of the round-trip time has passed without receiving an acknowledgment.
The Sky X gateway can also be used in multilink configurations where a single Sky X gateway hub unit enhances the performance of multiple separate outbound links from a single uplink facility. However, over satellite links, TCP misinterprets the papeer round-trip time and bit errors as congestion and responds inappropriately. SkyX Accelerator technology overcomes latency effect on TCP over high-bandwidth links by using bandwidth much more efficiently and improving replication performance over high capacity technloogy center-to-data center links.
PKTRthe global leader in WAN Application Optimization, today announced the introduction of two new SkyX Accelerator models based on new hardware platforms that provide substantially improved scalability to support future features and functional enhancements. Specifically optimized for long delay, high bit error and asymmetric bandwidth conditions.
However data 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 two Sky X gateways pass control data between each other, allowing the Sky X gateway on the opposite side of the satellite to appear to be the original source or destination device. The acknowledgements and error messages will always dominate the data transfer and the rate of flow reduces very much.

These results illustrate that TCP throughput drops rapidly as the round-trip time increases. Data Center Skyz Acceleration.
The Sky X gateway combines protocolapplication and system level enhancements to provide maximum throughput for satellite networks. Sky X gateway has been tested by many organizations and various independent third parties for a wide variety of different conditions and has been found satisfactory. 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.
Post a Comment leave your opinion. However the internet protocols are not optimized for satellite conditions.
The figure below shows the measured throughput on an error-free, 10 Mbps link. This architecture offers vastly improved performance while remaining entirely transparent to the end user and fully compactable with the internet infrastructure.

Sky X Multicast Fan-Out offers a simple and convenient solution for reliable multicast over wide area networks. tcehnology
The Sky X system delivers the web objects to the client side of the satellite link where they can be served locally when requested by oaper browser ,there by avoiding satellite delay. The Sky X FTP multicast facility is designed to provide multicast fan-out functionality tailored specifically for use with FTP, combining the power of multicasting with the convenience of the well-known and ubiquitous FTP utility.
