There are growing interests to provide telephone services over the Internet. In particular, Internet services providers (ISPs) may become the next generation telephone company especially in providing international telephone services. This paper proposes a novel method called quantum IP (QIP) for transporting international voice traffic over the ...

On voice quality of IP Voice over GPRS
2000 IEEE International Conference on Multimedia and Expo. ICME2000. Proceedings. Latest Advances in the Fast Changing World of Multimedia (Cat. No.00TH8532), 2002We consider the voice quality of IP Voice over a GPRS connection. We investigate how different speech codecs fit into GPRS packet data channels and the resulting subjective voice quality in a number of test cases.

Voice over IP versus voice over frame relay
International Journal of Network Management, 2004AbstractThis paper presents a comparison of the voice‐enabling features of the Internet protocol (IP) and frame relay (FR) networks. The discussion focuses on the issues that affect the quality of service of voice applications and the relative suitability of IP and FR for delivering voice applications.

Voice over IP on Wireless Networks
2006 2nd International Conference on Information & Communication Technologies, 2006Industry have adopted the Internet Protocol (IP) standard to route data over their corporate networks, this enables them to maintain a single infrastructure, which in turn reduces their maintenance costs. The implementation of Wireless Fidelity (WiFi) networking has allowed users to access the corporate network whilst maintaining mobility.

TCP-friendly transmission of voice over IP
European Transactions on Telecommunications, 2003In the last few years an increasing amount of attention has been paid to technologies for the transmission of voice over IP (VoIP). At present, the UDP transport protocol is used to provide this service. However, when the same bottleneck link is shared with TCP flows, and in the presence of a high network load and congestion, UDP sources capture most ...

Voice over IP over satellite links
ICECS 2001. 8th IEEE International Conference on Electronics, Circuits and Systems (Cat. No.01EX483), 2002Voice over IP (VoIP) services have recently emerged as a low-cost alternative to Public Switched Telephone Network (PSTN) voice service, and as an attractive solution for voice/data integration in public and private networks. Satellite links already have an increasing portion of their capacities used to carry data packets. Convergence of voice and data

Privacy of encrypted voice-over-IP
2007 IEEE International Conference on Systems, Man and Cybernetics, 2007In this paper, we present an early study on how timing-based traffic analysis attacks can be used to reconstruct the communication on end-to-end VOIP systems by taking advantage of the reduction or suppression of the generation of traffic whenever the sender detects a voice inactivity period.

AIP Conference Proceedings, 2012
Many analysts would agree that, had it not been for compilers, the improvement of spreadsheets might never have occurred. After years of robust research into scatter/gather I/O, we show the essential unification of checksums and Boolean logic. BOURI, our new application for interrupts is the solution to all of these obstacles.
