  • -A network can be defined as a group of computers and other devices connected in some ways so as to be able to exchange data. -Each of the devices on the network can be thought of as a node; each node has a unique address. -Addresses are numeric quantities that are easy for computers to work with, but not for humans to remember. Example: 204.160.241.98 -Some networks also provide names that humans can more easily remember than numbers. Example: www.javasoft.com, corresponding to the above numeric address. Internet address Consists of 4 bytes separated by periods Example: 136.102.233.

  • The main focus of the book is the advances in telecommunications modeling, policy, and technology. In particular, several chapters of the book deal with low-level network layers and present issues in optical communication technology and optical networks, including the deployment of optical hardware devices and the design of optical network architecture. Wireless networking is also covered, with a focus on WiFi and WiMAX technologies.

  • The performance of current transport systems is inadequate when viewed in terms of economic efficiency, sustainability, and safety. Towards Better Performing Transport Networks examines the tools that are necessary to effectively measure these systems and those that are required to improve them. Utilising advanced tools of network analysis, the contributors challenge various pieces of conventional wisdom and in particular the view that intermodal transport is more environmentally benign than road transport.

  • Chance events are commonplace in our daily lives. Every day we face situations where the result is uncertain, and, perhaps without realizing it, we guess about the likelihood of one outcome or another. Fortunately, mastering the concepts of probability can cast new light on situations where randomness and chance appear to rule. In this fully revised second edition of Understanding Probability, the reader can learn about the world of probability in an appealing way.

  • Frame Relay is a standardized wide area network technology that specifies the physical and logical link layers of digital telecommunications channels using a packet switching methodology. Originally designed for transport across Integrated Services Digital Network (ISDN) infrastructure, it may be used today in the context of many other network interfaces. Network providers commonly implement Frame Relay for voice (VoFR) and data as an encapsulation technique, used between local area networks (LANs) over a wide area network (WAN).

  • A bit (binary digit) is the smallest unit of information • N = 2n where N is the number of representations and n is the number of bits (ex. ASCII, Unicode, PCM code etc.) • Data communications transfer information using codes that are transmitted as signals (either analog or digital) • In general, analog lines provide a slow service that contains high error rates.

  • Since the publication of the first edition of this book in 1992, the state of the art of fiber-optic communication systems has advanced dramatically despite the relatively short period of only 10 years between the first and third editions. For example, the highest capacity of commercial fiber-optic links available in 1992 was only 2.5 Gb/s. A mere 4 years later, the wavelength-division-multiplexed (WDM) systems with the total capacity of 40 Gb/s became available commercially.

  • The efficient design of telecommunication networks has long been a challenging optimization problem. It is made difficult by the conflicting, interdependent requirements necessary to optimize the network’s performance. The goal of the designer is to produce a minimum cost network that allows maximum flow of information (in the form of messages) between multiple source-sink pairs of nodes that simultaneously use the network. An optimum design method must also produce a network topology that efficiently routes these messages within an acceptable amount of time...

  • Evolutionary Methods for the Design of Reliable Networks Alice E. Smith and Berna Dengiz Introduction to the Design Problem The problem of how to design a network so that certain constraints are met and one or more objectives are optimized is relevant in many real world applications in telecommunications (Abuali et al., 1994a; Jan et al., 1993; Koh and Lee, 1995; Walters and Smith, 1995), computer networking (Chopra et al., 1984; Pierre et al., 1995), water systems (Savic and Walters, 1995) and oil and gas lines (Goldberg, 1989).

  • Optimization Issues in Telecommunications The complexity and size of modern telecommunications networks provide us with many challenges and opportunities. In this book, the challenges that we focus on are those which involve optimization. This simply refers to scenarios in which we are aiming to find something approaching the ‘best’ among many possible candidate solutions to a problem. For example, there are an intractably large number of ways to design the topology of a private data network for a large corporation....

  • Technical Standards for Networks In the past, telecommunications networks have been evolved in the minds of their designers to meet well defined but changing user demands. These broadly innovative influences are bound to persist and users can look forward toever more sophisticated telecommunications services in the future.

  • Teletrafic Theory Telecommunication networks, like roads. are saidcarry ‘traffic’, consisting not of vehicles but of to telephone callsor data messages. The more traffic there is, the more circuits and exchanges must be provided. On a road network the more cars and lorries, the more roads and roundabouts are needed. In any kind of network, if traffic exceeds the design capacity then there will be pockets of congestion.

  • Soon after Samuel Morse’s telegraphing device led to a deployed electrical telecommunications system in 1843, waiting lines began to form by those wanting to use the system. At this writing queueing is still a significant factor designing and operating communications services, whether they are provided over the Internet or by other means, such as circuit switched networks.
