VoIP Architecture vs. Traditional Network Architecture
Before the advent of the Internet, interactive communications were solely made by telephone at PSTN line cost. With the beginning of highly advanced network technology, computers were being mass-produced and available to consumers at a lower price. People started to communicate with new services like e-mail, chat room and more on the Internet. These services were inexpensive and easy to apply, but they lacked the individual touch provided by the telephone. Thus, big corporations began to toy with the idea of permitting people to have instantaneous vocal communication.
Architecture basic VoIP entails the design set-up of the transmission of telephone calls over a data network like the Internet. In short, VoIP can send voice, fax as well as other information over the Internet, as opposed to through the (PSTN) or standard telephone network. A chief advantage of architecture basic VOIP and Internet telephony is that it totally evades the charges incurred by traditional telephone service.
With the architecture basic VoIP, the VoIP telephone calls or voice, bypass the customary switch telephone network and transmit voice calls throughout a private network (this is the same network that allocates the web, e-mail and data traffic). Voice over Internet Protocol or VoIP refers to the application of the Internet for generating telephone calls. The key advantage for PC users of VoIP connections is that they usually only have to pay their local Internet connection charges, no matter where they are calling anywhere around the globe. VoIP telephony threatens the traditional distance and time-based pricing model on which all main voice line telephone services are presently based. With voice applications, one of the most crucial devices in architecture basic VoIP is a Softswitch.
VoIP generally works on the reputable methods of sending packed digitized data throughout the Internet. TCP or IP networks are made of IP packets including a header to control communication and a payload to convey the data. VoIP architecture uses it to get across the network and arrive at the destination. While remitting information, analog data is digitized with the aid of an ADC (analog to digital converter).This is transmitted at one end and the data at the other end is transformed into the analog format with DAC (digital to analog converter) to utilize it. VoIP architecture works in a very similar manner. VoIP digitalizes voice in different data packets and then forwards them as they arrive at the destination and reconverts them back to voice at the destination.
Past Architectures and the New Trends in Architecture
Architecture basic VoIP describes networks that naturally cover data and voice (PSTN) communications.
The basic idea behind architecture basic VoIP is that all the information is transmitted via packets, much like the Internet. These packets in the architecture basic VoIP are labeled according to their type-whether its data, voice or anything else of that nature and handled dissimilarly for Quality of Service and other security functions by traffic management equipment.
Architecture basic VoIP is based on Internet technologies, which includes Internet Protocol (IP) as well as Multiprotocol Label Switching (MPLS).
The architecture basic VoIP permits decoupling the network’s transport and service layers; therefore, whenever a contributor wants to start a new service, he can do so by defining right at the service-layer without considering the transport layer.
Softswitch is a predetermined device that controls VoIP calls. It allows correct integration of different types of protocols within the VoIP architecture. The most vital function of the Softswitch is generating the interface to the existing telephone network or PSTN, via Signaling Gateways (SG) and Media Gateways (MG). However, the Softswitch may actually be defined differently by the different equipment manufacturers and have somewhat different functions and VoIP architecture.
One often finds the term Gatekeeper in the literature of VoIP solutions architecture. It was converted using gateways from analog or digital switched-circuit form to the IP. As soon as this kind of VoIP solutions architecture device started using the Media Gateway Control Protocol (MGCP), the name was eventually changed to Media Gateway Controller (MGC).
Classification of Internet traffic is developed into the structure of the IP datagram in the form of a three-bit wide Precedence field. This has always been an integral part of the Internet’s architecture. Until the emergence of multimedia and VoIP solutions architecture, this field was rarely used in practice. Of a matter of fact, the original deployment of TCP/IP was on about a dozen computers connected by traditional modems, which is an inappropriate platform for voice.
The older routers forwarded packets on a neutral basis because they weren’t capable of dividing traffic by top priority without introducing a delay. The modern routers, in VoIP solutions architecture, have more advanced logic that affords them to route instantaneous across several Classes of Service.
