Un seul réseau de communication – un seul monde – un internet
Summary

Summary/Abstract: The evolution of communication networks is first determined by the valueadded services spread over, as fixed or mobile telephony, television and Internet. If 5 years ago, data transfer monopolized the network bandwidth, today, traditional services as above-mentioned are migrating and taking over the Internet traffic. The transfer process of analog towards digital services is generally called convergence. For the undergoing theoreticians of the idea of unification, the following question aroused: “Does the use of a unique infrastructure mean convergence?”. Although, as shown in the present paper, nowadays the same infrastructure can occasionally be used (television, data access, fixed and mobile telephony), in a truly convergent network, all the services are transported using the same protocol, coded at source and decoded at destination according to necessities. Convergence stands for combining all four data transmission services into one convergent network.
