Transmission of voice over packet-based protocol has recently gained momentum. To this effect, Voice over Internet Protocol (VoIP) implementations on current and future versions of the Internet Protocols networks is becoming a convenient and inexpensive technology. This is the technology that is replacing traditional public switched telephone networks (PSTN). However, like any other such technology,...
Last few decades has brought many fundamental changes to data communications and the Internet. Internet has its roots in a networking project started by ARPA which consisted of four computers. Now the Internet spans the globe, and has become the default communication mechanism for businesses and individuals. IPv4 addresses will soon be exhausted, which has initiated development of IPv6. The new IP...
In this paper, the performance of IPv4 and IPv6 are compared for both Client-Server and Peer-Peer networks. For both networks, IPv4 produced higher bandwidth for TCP protocol. For UDP, IPv4 and IPv6 showed insignificant bandwidth differences except for packet size of 384 bytes where IPv4 had better performance in client-server environment.
We compare VoIP performance on IPv6 and IPv4 LANs in the presence of varying levels of background UDP traffic. A conventional softphone is used to make calls and a bare PC (operating systemless) softphone is used as a control to determine the impact of system overhead. The performance measures are maximum and mean delta (the time between the arrival of voice packets), maximum and mean jitter, packet...
Over the last decade, many fundamental changes have occurred in data communications and network infrastructure that will be shaping the future of information technology for years to come. This global network infrastructure, the Internet, is now at the core of communications for worldwide economy and individuals. Internet protocol (IP) v4 is the standard for the design and interconnection of networks...
A small network of computing devices that started as ARPANET project in early 1980s is now a worldwide network of devices for billions of users. This global network, the Internet, has become an integral part of worldwide economy and life of individuals. Internet Protocol (IP) v4 is the basic building block of the Internet and has served well, but it has limitations that hinder its growth. The solution...
