Network Security And Reliability (5657 words) |
 | Public and private networks are interconnected and use the facilities of each other to create a transparent "network of networks." As opposed to the past when the long-distance network was the sole responsibility and was under the control of ATandT, today's "network-of-networks" is a decentralized network in terms of control and overall responsibility. |
| Network failures indeed can have catastrophic results, and such failures must be prevented and minimized through adequate attention to the security of the network and the individual networks that comprise today's "network of networks." With competition, the reliability of tomorrow's network is at greater risk, according to a report of the National Research Council (1989). |
| The "network of networks" thus will be interconnected not only in terms of the transmission and switching of customer signals but also in terms of the signals that control the overall operation of the networks. |
| Access Network Planning and Technologies (1815 words) |
| Telecommunications today is perhaps the fastest evolving field of study. |
| It therefore becomes imperative for the access network planner to be familiar with both traditional and new technologies, structures and methods as their plans would have a profound long term impact on how the network shapes up and meets the desired objectives.. |
| A telecommunications network is therefore a system which can provide these services to a number of end users. |
