What are the key benefits of layered network?

The key principle of modern networking is the separation of network functionality into independent layers; this is also true in the tele and datacoms industry. The 'layered' thinking is also a very fundamental and visible aspect in a number of standardization initiatives and industry forums, such as Multiservice Switching Forum, led by several of the largest operators and manufactures.

3G mobile communication systems are designed with these principles in mind, and hence offer a number of advantages and possibilities. Special attention needs to be put on meeting the requirements for time-to-market, low cost of ownership, openness and future evolution towards an "all-IP" solution.

Key characteristics :

  • Offers an open and versatile architecture capable of meeting the current and future demand in a fast changing telecommunications environment.

  • Provides and inherent flexibility for coping with growth and/or changing traffic patterns and traffic mixes.

  • Independence between layers allows each layer to evolve independently.

  • Provides great transport flexibility and allows different transport technologies, both existing and new. To be deployed without impacting the control or services/application layers.

  • Allows common transport arrangements for multi-services network.

  • Allows access independent and seamless services through a common service/applications layer.

  • Provides efficient use of network resources.

  • Relies on proven and stable protocols and design.

  • Allow a very flexible re-use of investments in the GSM infrastructure.

What is the main limitation of microwave transmission?

  1. The main limitations to Microwave transmission is the fact that it needs line of sight and that it can be subject to interference such as planes passing over, or rain

How did the widespread adoption of the OSI model change the development of network technologies?

he widespread adoption of the OSI model changes the development of network technologies in many ways. Most traditional communications media including telephone, music, film, and television are reshaped or redefined by the Internet, giving birth to new services such as Voice over Internet Protocol (VoIP) and Internet Protocol Television (IPTV). Newspaper, book and other print publishing are adapting to Web site technology that have reshaped into blogging and web feeds. The Internet has enabled or accelerated new forms of human interactions through instant messaging, Internet forums, and social networking. Online shopping has boomed both for major retail outlets and traders. Business-to-business and financial services on the Internet affect supply chains across entire industries.

The early development of LANs, MANs, and WANs was confused in many ways. The early 1980s saw great increases in the number and sizes of networks. As companies realized that they could save money and gain productivity by adoption of the OSI model. The existence of the model makes it easier for networks to be analyzed, designed, built and rearranged, by allowing them to be considered as modular pieces that interact in predictable ways, rather than enormous, complex monoliths. Today's data communications environment differs from that of 20 years ago in that it reduces complexity, possess standardized interfaces, facilitates modular engineering, ensures interoperability between vendors, simplify teaching and learning.
