-------------------------------------------------------------------ABSTRACT---------------------------------------------------Voice over Internet Protocol (VoIP) is a methodology and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. VoIP provides a protected transmission of private voice data betwee...

Multiprotocol Label Switching (MPLS) is the latest technology in the evolution of routing and forwarding mechanisms for the core of the Internet. It ensures the reliable delivery of the Internet services with high transmission speed and lower delays. Traffic Engineering (TE) in MPLS is used for effectively managing the networks for efficient utilization of network resources. MPLS technology mak...

1 1 SUMMARY The sustained rate of technological change in the telecommunications industry has opened up significant windows of opportunities for telecommunications networks operators to develop value-added services and multimedia applications. The growth of the Internet raises the issue of a possible migration from traditional circuit-switched networks designed for basic voice communication tow...

As the telegram was replaced by telephony, so to Voice over IP (VoIP) systems are replacing conventional switched wire telephone devices, these systems rely on Internet connectivity for the transmission of voice conversations. This paper is an outline of ongoing preliminary research into malfeasant VoIP activity on the Internet. 30 years ago PABX systems were compromised by hackers wanting to m...

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...

In this paper, we describe an XML based 3D-Voice Enabled Single Transmission Multiple Display Multimedia Language (3D-VE STMDML) model and its implementation. We describe 3D-scenes, mesh based 3D objects, integration of 2D and 3D objects, object animations with collision avoidance, and voice based animation control. This model has been used to download object based movies over the Internet, dyn...
