IP-over-Satellite: Internet Connectivity Blasts Off.
This article was about sending information packets over satellites. With the inevitable increase in people and businesses joining the already crowded internet, many companies are looking towards a non terrestrial based way of to share files and transmit information. .
Satellites are now being used as links between earth based networks. The use of satellites to move information is not a new technology. It was invented in the 1960s by the military for their purposes. Satellites can provide direct communication over large distances anywhere around the world without the use of tangible wires. They also bypass the congested lines held by telephone companies and internet service providers. With the technology to build more powerful satellite transponders, satellites can deliver bandwidth speeds up to 155 megabits per second. These speeds allow companies to use high bandwidth applications such as streaming data or video and web casting. And because there are no cables between links, information can be shared with the most remote, hard to reach areas of the world. .
Satellites are configured in a number of different ways. "Bent pipe" involves concatenating the uplink to the downlink at the satellite to form a single transparent communication channel between the source and destination addresses on earth. The satellite basically "reflects" the original message back down to earth. This is the simplest configuration but entails the highest chance for problems. Antenna size, power requirements, and atmospheric factors could cause issues of attenuation. The second configuration talked about by the article is the OBP, or on board processing. This involves a constellation, or network of satellites connected by intersatellite links. These intersatellite links, or ISLs, typically use at least 60 GHz frequencies and operate at speeds higher than 1 gigabit per second.
IP is a connectionless protocol. ... The Source IP address and the destination IP address specify the sending and receiving node, respectively, and are both 32 bits long. The options field allows IP to support various options. ... IP addressing is a vital part of the IP protocol. ... IP is the heart of internet protocols. ...
Introduction TCP (transmission control protocol) and IP (internet protocol) "TCP/IP were developed by a Department of Defense (DOD) research project to connect a number different networks designed by different vendors into a network of networks (the "Internet"). ... Description TCP/IP Technology The technical aspects of TCP/IP, related protocols, and the environments in which these protocols operate. ... IP is the primary layer 3 protocol in the Internet suite. IP provides error reporting and fragmentation and reassembly of information units, for transmission over networks with dif...
Satellite is probably the most useful invention since the wheel. ... TVS and radios are also turning to the use of satellites. ... Satellites were built and tested on the ground. ... Once a satellite shuts down, the program uploaded to the satellite will tell it to fold up it's solar panels and remain in its orbit. ... That's a satellite per 36,000 people. ...
The advantages of SONET/SDH include the following: • rapid point-to-point transport of data with little overhead • standards-based multiplexing of SONET/SDH datastreams • transport independent from the services and applications that it supports • self-healing ring structure to reroute traffic around faults within a particular link • widely deployed transmission infrastructure within carrier networks • TDM grooming and aggregation from the DS0 level Figure 1: A SONET/SDH Pipe Carrying ATM Transporting IP over SONET/SDH: The terms IP over...
The Internet Protocol, known as IP, works as an addressing system on networks by using IP numbers. IP numbers are assigned in ranges for companies to use for their networks, with each computer assigned it's own Real IP address. IP numbers are twelve numbers long, separated every third by a decimal. Computers communicate over the network by sending information to individual IP addresses, and if needed, a server acts as a link to a router or other networks. ... Even George Lucas' Industrial Light and Magic special effects studio has switched over to Linux says USA Today in a September ...
Two recent emergences of these advancements are Voice Over IP (usually referred to as VoIP) and Very Large Scale Integration (also known as VLSI). ... Many benefits outline Voice over IP. ... The capabilities are endless with the revolutionary Voice over IP. ... With the new benefits and applications of Voice over IP, it is too good to resist. It is why vendors are flooding the market with VoIP products and services, such as net telephones and Fax over Ip, which allows to fax over the VoIP network. ...
With the rise of use of protocol, VOIP (Voice over Internet Protocol). ... The customer could also use system such as analog telephone adapter which interacts with the conventional analog phone to the IP equipment or it could also be an IP phone that has built in interface and networking technology attached to the desktop set. ... Most digital system that are being used today mainly use proprietary hardware or protocol which provides IP interface. ... Another disadvantage of the IP phone is that it is very difficult to trace the exact location of IP phone because they rely on Internet services...
Over the last forty years, weather satellites have given us the ability to extend our capability to accurately forecast weather conditions. ... The video systems relayed thousands of images showing cloud cover over the Earth. ... Noordung had built a mathematical model that stated that an object placed over the equator at an elevation of 22,238 miles with a speed of 6878 miles per hour would appear to stand still to an observer on Earth. ... It had the capability to not only monitor weather conditions but also served as a relay for meteorological data from over 10,000 locations to a central pr...
