Nowadays, most IPTV senders provide all of their multiple streaming channels under IPv4 protocol, in dedicated networks, which are high bandwidth but costly and having geographically limited number of subscribers located relatively close to IPTV senders. Due to the increase of Internet bandwidth, IPTV providers seem to offer incredibly better television standard with HD IPTV. In this paper we adopt...
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,...
The performance of category 5e and category 6 cabling systems is compared for both IPv4 and IPv6 using Gigabit Ethernet LAN. The maximum bandwidth achieved over Gigabit Ethernet was 700Mbps and it was for IPv4 and category 5e cabling. IPv4 and IPv6 resulted in better TCP and UDP throughput on Category 5e than it did with Category 6.
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...
We conduct experiments in a LAN environment to determine the impact of IPsec and 6to4 encapsulation on VoIP quality in future IPv6 networks. We measure VoIP performance in the presence of varying background traffic for each of four IPsec scenarios with IPv6 and 6to4 encapsulation, with and without NAT, and compare with IPv4. The scenarios reflect situations commonly encountered in today's VPNs including...
