Potentially large network delay variability experienced by voice packets when travelling over IP networks complicates the design of a robust voice conference bridge. Intrastream synchronization is required at the conference bridge to smooth out network delay jitter on a given stream and provide a continuous stream of voice packets to the conference bridge core. Interstream synchronization is ne...

This document depicts many common Voice over IP (VoIP) use cases for Session Initiation Protocol (SIP) peering. These use cases are categorized into static and on-demand, and then further subcategorized into direct and indirect. These use cases are not an exhaustive set, but rather the most common use cases deployed today. Status of This Memo This document is not an Internet Standards Track spe...

In this paper we investigate denial of service (DoS) vulnerabilities in Voice over IP (VoIP) systems, focusing on the ITU-T H.323 family of protocols. We provide a simple characterisation of DoS attacks that allows us to readily identify DoS issues in H.323 protocols. We also discuss network layer DoS vulnerabilities that affect VoIP systems. A number of improvements and further research direct...

The paper deals with the admissibility of voice traffic flows with QoS requirement in terms of packet delay and packet loss. A twostage CAC approach based on the rate envelope multiplexing principle along with a simplified reference model is proposed. One concrete realization of such a CAC mechanism that utilizes the Chernoff bound based effective bandwidth and the recently stated negligible ji...

Supporting mobility in real-time applications such as Internet telephony is in demand as mobile Internet becomes prevalent. A simple solution is to use Mobile IP in order to provide transparent handoffs to upper layer applications. However, due in part to the Mobile IP’s limitations such as triangular routing delay and encapsulation overhead, application-layer solutions for mobile Internet tele...

Voice-over-IP is a growing technology. Companies are beginning to consider commercial investments in these services. Will it be able to provide the quality of service necessary to satisfy customers? If not what will need to be done to remedy the situation.

-------------------------------------------------------------------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...

An Approach for Improving Performance of Aggregate Voice-over-IP Traffic. (August 2005) Camelia Al-Najjar, B.S., University of Jordan Chair of Advisory Committee: Dr. A. L. Narasimha Reddy The emerging popularity and interest in Voice-over-IP (VoIP) has been accompanied by customer concerns about voice quality over these networks. The lack of an appropriate real-time capable infrastructure in p...

Network is essentially a distributed information system providing access to shared data objects between networking applications running on different nodes. As the Internet gains its rapid growth, new and more demanding networking applications start to emerge such as voice over IP, storage over IP and media streaming. To cope with the demands of these applications, the underlying network process...
