The Convergence of Telecommunications and Computing

The advent of emerging technology and trends in the fields of communications and computing has led to a transformation characterized by a notable convergence of telecommunications and computing creating totally different and new paradigms, either self-contained or disparate. Telecommunications infrastructure today is running the most software and data intensive services consuming tremendous computing resources and computational processes. The convergence of telecommunications and computing has been noticed and commented on for some time. At present, there is a much richer interrelationship than at any other time in the past. These fields will become virtually distinguishable in the very near future. The convergence has, and will continue to have, a profound impact on technology, industry, and their larger society. Telecommunications and computing have already been irreparably changed one by the other, and as we argue below, will be even more substantially recast in the future. Much more profound changes are forthcoming, changes no less weighty than the rapid disintegration of the vertically integrated industrial model. While computing in the absence of communications has led to new applications and made substantive changes to leisure and work life, computing in conjunction with communications will have a profoundly greater impact on society. This is because communications are at the heart of what makes a society and civilization, and the convergence with computing will revolutionize the nature of those communications. The classical terminology of telecommunications and computing is no longer useful. In light of this, it is appropriate to define a more transparent classification of networked applications that is media-blind and focuses on the functions provided by the user.
To further grasp this concept, we will adopt the three-level model model for an information network and its services and applications, as shown in the figure. We define an applications as a collection of functionality that provides value to a user. We will be concerned here with networked applications, implying that are distributed across a distributed telecommunications infrastructure, which is available for use in building all applications. Bit ways are network mechanisms for transporting bits from one location to another. Example of networked applications are e-mail, IP telephony, database access, file transfer, www browsing, and video conferencing. Examples of services would be audio or video transport, file system management, printing, electronic payment mechanisms, encryption and key distribution, and reliable data delivery.
Today, emerging broadband communications technologies such as 4G/LTE is imposing a direct migration to all IP network which implies a significant utilization of the IP protocol's implementations on various computing platforms in order to make things work as supposed to. And this denotes a quasi complete convergence of telecommunication and computing as we are proceeding.
