Download or read book Compressed Internet Protocol IP Data Via Geosynchronous Earth Orbit GEO Satellite Circuits written by and published by . This book was released on 2002 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: To enable Internet Protocol applications in the submarine environment, Critical Technologies Inc. (CTI) has defined requirements for an integrated system of enhanced Data Link, Network and Transport protocols (in OSI Layers 2-4) and an innovative Application Traffic Controller (ATC, in OSI Layers 5-7). It integrates caching, compression, prioritization and queuing to optimize link utilization. The Compression Controller segment will provide users with compression benefits without requiring them to manually invoke compression utilities. It will automatically and transparently, based upon policy rules, for each data object: determine whether the data requires compression, and if so, which algorithms and parameters are most appropriate for that data; and then dispatch the object to the most appropriate available external compression utility. Navy system administrators will define the rules, based on Application Layer data object type, size, format, content, intended use, importance, source/destination, etc., per approved doctrine. In addition to automating compression, it will provide better control over the tradeoffs among delivered data quality, timeliness and wireless resource consumption. In the Phase I Option, CTI developed a Compression Controller pre-prototype and successfully tested it over UHF DAMA MILSATCOM.

Available in PDF, EPUB and Kindle. Book excerpt: To enable Internet Protocol (IP) applications in the submarine environment, Critical Technologies Inc. (CTI) has defined requirements for an integrated system, comprising enhanced Data Link, Network and Transport protocols (OSI Layers 2-4), and an innovative Application Traffic Controller (ATC, operating in OSI Layers 5-7). The system will optimize efficiency and effectiveness of fleet communications, despite submarine SATCOM's high Bit Error Rate, low bandwidth, long latency, extreme channel variability and severely intermittent connectivity. The ATC integrates caching, compression, prioritization and queuing, under control of system-administrator specified rules, to optimize link utilization. The system is also designed to operate under Low Probability of Detection I Intercept and EMCON (with planned and unplanned blackouts, in various constrained 2- and 1-way communications postures), by integrating enhanced protocols that provide reliable transport of IP traffic to submarines without acknowledgement. The system will benefit various assets of the current and future US fleet, as well as other military and commercial organizations. These assets could include fast attack and ballistic missile submarines, surface ships, airborne platforms, unmanned vehicles, littoral elements, and various land, sea, air, and space networks.
Download or read book Low Earth Orbit Satellite Internet Protocol Communications Concept and Design written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-06-03 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents a design concept for a low-Earth-orbit end-to-end Internet-Protocol- (IP-) based mission. The goal is to maintain an up-to-date communications infrastructure that makes communications seamless with the protocols used in terrestrial computing. It is based on the premise that the use of IPs will permit greater interoperability while also reducing costs and providing users the ability to retrieve data directly from the satellite. However, implementing an IP-based solution also has a number of challenges, since wireless communications have different characteristics than wired communications. This report outlines the design of a low-Earth-orbit end-to-end IP-based mission; the ideas and concepts of Space Internet architectures and networks are beyond the scope of this document. The findings of this report show that an IP-based mission is plausible and would provide benefits to the user community, but the outstanding issues must be resolved before a design can be implemented.Slywezak, Richard A.Glenn Research CenterINTERNETS; LOW EARTH ORBITS; PROTOCOL (COMPUTERS); SATELLITE COMMUNICATION; REMOTE SENSING; COMMUNICATION SATELLITES; INTEROPERABILITY
Download or read book Transport Network and Data Link Layer Protocol Designs to Improve Geo stationary Earth Orbit Satellite Data Set Transmission Performance written by Paul Douglas Wiedemeier and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Geo-stationary earth orbit (CEO) satellites are wireless transmission media that provide near-earth Internet and Intranet data communication, but are limited to low Megabits per second transmission rates and small messages. They can provide communication infrastructure to rural earth locales, are not affected by terrorist events and natural disasters that render terrestrial channels unusable, and can replace terrestrial communication infrastructure. In this thesis, we present new designs for a transport layer data transmission protocol, a network layer routing strategy, and a data-link layer medium access control strategy. Through simulation, we show that our designs permit earth stations to transmit large data sets at high transmission rates over GEO satellites in less time than the Transmission Control Protocol variant Reno and frequency division multiplexing. Our designs can be used by organizations that wish to transmit large data sets quickly over CEO satellites that exhibit large bandwidth delay products and large bit error rates.

Download or read book Satellite Newsgathering written by Jonathan Higgins and published by Taylor & Francis. This book was released on 2012-08-06 with total page 600 pages. Available in PDF, EPUB and Kindle. Book excerpt: Praise for the first edition: "It is a wonderful source of information and has the merit of going straight to the subject, being technically precise although very easy to understand. There are numerous pictures, photographs, diagrams, which make the reading a real pleasure." --European Broadcasting Union Technical Review "The complexity of a satellite newsgathering system could be a four-month long college course with a high tuition rate and an enrolment number so large you have to watch your professor on a TV screen. Jonathan Higgins might have saved the independent learner a few attendance point deductions by fitting it into one book." --Satellite Broadband magazine An ideal introduction for anyone working, or interested, in satellite newsgathering (SNG). The new edition of this popular book builds upon the success of the first--an important and valuable work that is extermely easy to read, comprehensive in its treatment, and detailed where necessary. SNG used to be an immensely complex and expensive affair where broadcasting organizations were at the mercy of an expert who sat in a lonely corner, until needed. Things have changed--everyone in a global news organization needs to know about it now. This is not only because of the high costs of mistakes, but because now even non-technical journalists on the ground have to operate their own equipment. Learn the skills, basics of equipment, cutting edge technology and critical safety issues of satellite newsgathering.
