Network convergence refers to the provision of telephone, video and data communication services within a single network. In other words, one pipe is used to deliver all forms of communication services. The process of Network Convergence is primarily driven by development of technology and demand. One main goal of such integration is to deliver better services and lower prices to consumers. Users are able to access a wider range of services, choose among more service providers. On the other hand, convergence allows service providers to adopt new business models, offer innovative services, and enter new markets. == Introduction == The dictionary definition of “convergence” provides a starting point for the analysis: “the act of converging and esp. moving toward union or uniformity.” 〔Webster’s Ninth New Collegiate Dictionary, Merriam-Webster, Inc., Springfield, MA, p. 286, 1985.〕 Convergence implies the integration of telecommunication, broadcasting and Internet network services.

In the past, it is restricted to either communicating people by wire line or to watch broadcast programming at the same time. Two-way communication has been limited to voice and text by the limited availability of bandwidth; broadcast media have been restricted by their one-way character and by the availability of spectrum. Nowadays technology development, fierce competition and deregulation have transformed several distinct communications service markets into a converged market. In the telecommunications world, convergence has come to mean a moving towards the use of one medium as opposed to manipulation of all forms of information including voice, data and video across all types of network instead of carrying information separately within distinct networks. In the convergent network, different forms of information can be re-engineered to provide better, more flexible service to the user. For example, telephone networks can transmit data and video and cable networks are able to provide voice services...
