The Synchronous optical network, commonly known as SONET, is a standard for communicating digital information using lasers or light emitting diodes (LEDs) over optical fiber as defined by GR-253-CORE from Telcordia. It was developed to replace the PDH system for transporting large amounts of telephone and data traffic and to allow for interoperability between equipment from different vendors.

The more recent Synchronous Digital Hierarchy (SDH) standard developed by ITU (G.707 and its extension G.708) is built on experience in the development ....etc

ABSTRACT
In the near future, a pervasive computing environment can be expected based on the recent progresses and advances in computing and communication technologies. Next generation of mobile communications will include both prestigious infrastructured wireless networks and novel infrastructureless mobile ad hoc networks (MANETs). A MANET is a collection of wireless nodes that can dynamically form a network to exchange informat ....etc

Optical Networking Technology


Who needs more bandwidth?
Increased bandwidth demand will arise from a proliferation of applications such as data and call centers, as well as by the bootstrapping effect of increased consumption resulting from lower rates. For example, if the STD charges are reduced to one tenth of what they are today, I still do not expect to see my phone bill go down because my wife’s phone calls will just become ten times longer

Introduction to Networks
A computer network, often simply referred to as a network, is a collection of computers and devices interconnected by communications channels that facilitate communications among users and allows users to share resources. Networks may be classified according to a wide variety of characteristics. A computer network allows sharing of resources and information among interconnected devices.
A computer network is a collection of PCs and other devices c ....etc

RedTacton An innovative Human Area Networking technology that uses the surface of the human body as a transmission path

RedTacton is a new Human Area Networking technology that uses the surface of the human body as a safe, high speed network transmission path. RedTacton uses the minute electric field emitted on the surface of the human body. Technically, it is completely distinct from wireless and infrared. A transmission path is formed at the moment a part of the human body comes in contact with a RedTacton transceiver. Physically separati ....etc

Home Networking is the collection of elements that process, manage, transport, and store information, enabling the connection and integration of multiple computing, control, monitoring, and communication devices in the home. The price of home computers keep falling, while the advantages for consumers from being connected online investing and shopping, keeping in touch with long distance friends and tapping the vast resource of the Internet CE keep multiplying. No wonder an increasing number of households own two or more PCs.Until recently, the ....etc

In the recent years communication technology and services have advanced. Mobility has become very important, as people want to communicate anytime from and to anywhere. In the areas where there is little or no infrastructure is available or the existing wireless infrastructure is expensive and inconvenient to use, Mobile Ad hoc NETworks, called MANETs, are becoming useful. They are going to become integral part of next generation mobile services. A MANET is a collection of wireless nodes that can dynamically form a network to exchange informati ....etc

Introduction
Increasingly, network applications must communicate with counterparts across disparate networking environments characterized by significantly different sets of physical and operational constraints; wide variations in transmission latency are particularly troublesome. The proposed Interplanetary Internet, which must encompass both terrestrial and interplanetary links, is an extreme case. An architecture based on a least common denominator protocol that can operate successfully and (where required) reliably in multiple disparate e ....etc
