Talking about internet network can direct our thoughts floated the infrastructure, such as fiber optics, telephone, radio or even satellite. While not wrong, it shows that our minds are still focused on things that are physical. So, whether non-physical things associated with the Internet? The answer is that IP.
Like other aspects of our lives. Internet was built by the infrastructure and ultrastructure. Ultrastructure internet is a series of rules called a protocol. Collectively, these protocols form the Internet Protocol or IP. This standardized set of rules that allow computers to communicate over a network.
Major progress achieved by the Internet has led to a tendency for the Internet to all things. Currently, we have been able to listen to radio broadcasts, watch television, to phone calls and SMS were joyful over the Internet.
Have terfikirkan how to connect the radio waves and television with the Internet? Or, how to connect VoIP calls to landline and cell phones? Here ultrastructure internet role to unify all the modern communications media or are known by the term IP Convergence.
VoIP and IPTV.
IP Convergence refers to the ability of the Internet to act as a single foundation for a variety of functions that traditionally have their own protocols respectively. The easiest example is the telephone system.
Home phone (PSTN) to support the traditional phone system is a network of copper cables, circuit boards, and switches that transmits analog voice data from one plane to another phone. In further development, the engineers turned a lot of the PSTN into a digital system.
Furthermore, the invention allows us to make VoIP phone calls over the Internet. Here we make the Internet itself as a telephone network. To make a VoIP call, we use an adapter for a traditional phone, a special VoIP handset, or a PC that has installed VoIP applications.
In this invention, two different networks (data and voice) can be consolidated into a single platform. This is called IP Convergence. IP Convergence itself is not limited to data and voice. Video services can be integrated into the IP Convergence. Internet Protocol Television (IPTV) is an example.
