What makes VoIP over DOCSIS 1.1 and PacketCable networks better than over the Internet?
|
IP networks that are managed by DOCSIS and PacketCable standards can identify real-time packets like VoIP and gaming. These high-priority packets are routed with less processing delay than other packets where packet delay is not an issue. The Internet has no universal method to identify and priortize VoIP packets; only a namaged IP network can do that, like the one defined by PacketCable.
