Increasing number of Internet users forced them to use popular services, television and telephone, to use the Internet as a medium to reach their customers. Organizations are now applying VoIP and MPLS for providing the convergence of voice and data communications over single network infrastructure. VoIP (Voice over Internet Protocol) usage all over their branches, this reduces a huge amount of...

Today's era of packet switched networks demands larger bandwidth to suffice the need to integrate multimedia applications like Internet gaming, transmission of voice etc. It becomes necessary to judge the network performance with the allocated bandwidth. Network performance depends mainly on the efficiency of the protocol used in addition to load on the network, the transmission system typ...

The Internet’s phenomenal growth, worldwide coverage and increasing data delivery capabilities have made possible its use as an alternative communications medium for real-time voice messages. In addition, using the Internet medium for voice communication circumvents the high costs of long-distance phone rates. This paper discusses the functional architectural design of an Internet Telephony Gat...

Voice over Internet Protocol is a category of hardware and software that enables people to use the Internet as the transmission medium for telephone calls by sending voice data in packets using IP rather than by traditional circuit transmissions of the PSTN. The transmission of real time voice data is not as easy as ordinary text data and the real time voice transmission faces lot of difficulti...

One of the most successful WLAN protocols is IEEE 802.11. That is due to the simplicity and robustness against failures of its medium access control protocol. In addition, IEEE introduces the standard 802.11e for quality of service support. However, this standard is not considered efficient when used for some applications that don’t involve data and background in the transmission, but only voic...

Article History: Received 5, May, 2015 Received in revised form 12, May, 2015 Accepted 6, June, 2015 Published online 28, June, 2015 VoIP (Voice Over Internet Protocol) is an advanced technology that has a great potential to develop new telecommunication with much lower cost and better QoS. VoIP, a new technology has been increasingly popular in recent times due to its affordability and reduced...

-Voice over Internet Protocol (VoIP) is one of the fastest growing applications over Internet. The quality of service of VoIP can be measured by ITU E-model which is a subjective measure. In this paper, we discuss a novel method using Artificial Neural Network (ANN) to predict quality on real time traffic. It overcomes the drawback of available methods. NN has learning capability, so it can ada...

This paper describes the approach taken for the development of an Internet telephone software system which functions like a conventional telephone to support real-time voice communications over the Internet. The system allows voice to be captured and digitised at the source machine. Using Internet as the transmission medium, these voice samples are then transmitted to the destination machine wh...
