The Sky X gateways are available as ready to install hardware solutions which can be added to any satellite network. Response times improve dramatically with enhanced HTTP performance. The combination of its layer 7 classification, analysis, control, and reporting capabilities enables network administrators to keep critical traffic moving at an appropriate pace through bandwidth bottlenecks and prevents any single type of traffic from monopolizing the link. The Sky X protocol is designed to respond efficiently to typical satellite latency, bit errors and asymmetric bandwidth conditions and to take advantage of optimizations possible on a single-path link with known bandwidth. Policy-based enforcement of application priorities and bandwidth allocation for capacities of up to MB: So the throughput over the satellite networks is restricted to only a fraction of available bandwidth. The following file transfer tests illustrate the benefits of Sky X performance enhancement for different windows sizes, link band-widths, round-trip times, and bit error rates.
The Sky X gateway combines protocol , application and system level enhancements to provide maximum throughput for satellite networks. We can overcome these restrictions by using the Sky X protocol. Newer Post Older Post Home. Differentiate network delay from server delay. Also use at both sides of the link in a point-to-link as well as in fully meshed networks.
So it is desirable to design a separate protocol xkyx communication through the satellite to eliminate the disadvantages of using TCP over the satellite link. Sky X multicast fanout functionality is ideal for file transfers, cache skhx, video file distribution, content delivery networks, database replication, and any other distribution of data or files to multiple users over a satellite link or other wide area network.
Because there is only a single path over the satellite with no intermediate routing, any gaps in the packet sequence can be assumed to be data loss due to corruption rather than network congestion. Combinations of the criteria are supported, enabling more targeted monitoring and control.
Performance benefits from applications other than Web and file transfers depend on the characteristics of the applicationbut will typically fall between these two extremes. However many implementations of TCP are limited to maximum window size of 64 KB and most operating systems use a default window size of only 8 Tfchnologyimposing a maximum throughput rate over a satellite link of only Kbps per connectionregardless of the bandwidth available.
The new SkyX and high-end SkyX Accelerators support a greater range of link speeds and concurrent sessions than their predecessors and utilize the new release 7. The statements contained in this press release that are not siyx historical are forward-looking statements within the meaning of Section 21E of the Securities and Exchange Act ofas amended, including statements regarding Packeteer’s expectations, beliefs, intentions or strategies regarding the future.
Free maintenance service, Free mail id on your website name. 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.
Unfortunately, the only multicast capability built into the Internet Protocol is a UDP-based, unreliable, best-effort service that is only appropriate for real- time streaming applications such as event broadcasting. The reesearch Sky X gateways pass control data between each other, allowing the Sky X gateway on the ersearch side of the satellite to appear to be the original source or destination device.
Data Center Replication Acceleration. Also use at both sides of the link in a point-to-link as well as in fully meshed networks. For more information, contact Packeteer at 1 or visit the company’s website at www. No changes are required to the client or server and all applications rexearch to function without modification. Policy-based enforcement of application priorities and bandwidth allocation for capacities of up to MB: The Sky X s,yx delivers the web objects to the client side of the satellite link where they can be served techbology when requested by the browser ,there by avoiding satellite delay.
The combination of its layer 7 classification, analysis, control, and researcu capabilities enables network administrators to keep critical traffic moving at an appropriate pace through bandwidth bottlenecks and prevents any single type of traffic from monopolizing the link.
Minimize retransmission and recover more quickly from ppaper. The Sky X gateway combines protocolapplication and system level enhancements to provide maximum throughput for satellite networks. The graph given below shows the throughput as a function of the bit error rate for a 10 Mbps satellite link using a 1 MB TCP window.
Sky X Multicast Fan-Out offers a simple and convenient solution for reliable multicast over wide area networks. The Sky X Gateway transparently enhances the performance of all users on a satellite network without any modifications to the end clients and servers. Connections from applications running on the PC are intercepted and sent over the satellite using Sky X tdchnology.
XTP technologgy an open standard developed by the XTP Forum, a non-profit organization composed of networking protocol researchers, implementers, and user organization. Through the use of common TCP based applications such as FTP, the Sky X gateway can deliver a file to every remote location across a wide area network with only a single multicast transfer.
Fast Start Web Acceleration.
Computer Science (CSE) Seminar Topic on Sky X Technology
Specifically optimized for long delay, high bit error and asymmetric bandwidth conditions. OCR is an optical character recognition and By taking advantage of reliable multicast functionality built directly into XTP, the open-standard transport- layer protocol used by the Sky X Gateway to transfer data over the WAN linkthe Sky X Gateway provides fast, efficient, fully reliable multicast file transfers. The Sky X system delivers the Web objects to the Sky X gateway on the client side of the satellite link where they can be served locally when requested by the browser, avoiding the satellite delay.
Window Size and Link Speed vs. Packeteer assumes no obligation to update any such forward-looking statements.

This wastes available bandwidth when it transmits at too low a rate, and causes unnecessary retransmissions when it transmits at a rate higher than the bandwidth of the link. Reseqrch are ideal for providing internet and private network access over long distance and to remote locations.
Monitor response time for each application.
