This paper surveys packet loss in Voice over Internet Protocol (VOIP). The voice quality is affected by many network impairments. IP networks are on a steep slope of innovation that will make them the long term carrier of all types of traffic, including voice. Such networks are not designed to support real time voice communication because of their variable characteristics. The conversational qu...

Voice over IP (VoIP) is a communication technology allowing voice traffic transmission as data packets over a private or a public IP network. VoIP allows significant benefits for customers and service providers including cost savings, services integration, and systems extensibility. Nevertheless, the VoIP technology suffers from many hurdles such as architecture complexity, interoperability pro...

The popularity of Voice over the Internet Protocol (VoIP) for providing voice communication over IP networks such as the Internet has resulted in VoIP becoming a global telephony service. VoIP applications convert analogue voice signals into a digital format, which is then encapsulated into IP packets for transmission over the Internet. Our research has examined both the security and privacy im...

Voice over IP (VoIP) is the technology allowing voice traffic transmission as data packets over a private or a public IP network. VoIP allows significant benefits for customers and communication services providers. The main are cost savings, rich media service, phone and service portability and mobility, and the integration with other applications. Nevertheless, the deployment of the VoIP techn...

While Internet Telephony (IP Telephony) encompasses many different architectures and services, the key idea is the transport of real-time voice traffic over the Internet. IP Telephony architecture [2] allows the entire end-to-end path or a portion thereof to be routed over the Internet. The endpoints are regular personal computers (PCs) that are equipped with IP Telephony software which allows ...

Voice over IP (VoIP) service has been widely deployed over the prevalent Internet due to the advanced technologies of digital voice compression, communication protocols, and wired/wireless networks. VoIP then benefitmuch lower cost of equipment, operation, and better integrationwith data applications than voice communications over telephony networks. On the other hand, VoIP further introduce se...

This paper presents fundamental aspects of MPLS over ATM method, IP over ATM method and multimedia application traffics with different quality of service (QoS) needs. Using a simulation program, the MPLS over ATM method providing ABR, CBR & VBR QoS support, and the IP over ATM method providing UBR QoS support for transferring data, voice and video traffics are modeled. Having simulated the mode...

Mobile Internet Protocol (MIP) is a standard protocol that allows users to maintain nonstop connectivity with their home IP addresses regardless of physical movement. In this paper, we give an overview of Mobile IP: terminology, functionality, and operation. Comprehensive surveys on Mobile IP issues are discussed: Quality of Service (QOS), Multicast, Security, Voice, and TCP over Mobile IP. The...

The convergence of traditional telecommunications and the Internet is creating new network-based service delivery opportunities for telecommunications companies carriers, service providers, and network equipment providers. Voice over Wireless IP is one of the most exciting new developments emerging within the telephony market. It is set to revolutionize the delivery of mobile voice Services and...

Spam over Internet Telephony is becoming a large problem of the Voice over IP Architectures. Voice over IP has become a valid alternative to the Public Switched Telephone Network and it has a new paradigm for providing telephony services at a lower cost and higher flexibility. In the meantime, with Voice over IP the privacy becomes so hard and the benefits introduced are as strong as the securi...
