DESCRIPTION
Sending voice signals over the Internet is called Voice over IP or VoIP. Session
Initiated Protocol (SIP) is an internationally recognized standard for
implementing VoIP. SIP is an application-layer control (signaling) protocol that
handles the setting up, altering and tearing down of voice and multimedia
sessions over the Internet.
SIP is transported primarily over UDP but can also be transported over TCP.
BitTorrent is a free P2P (peer-to-peer) sharing tool allowing you to distribute
large software and media files. BitTorrent requires you to search for a file with a
searching engine yourself. It distributes files by corporation and trading, that is,
the client downloads the file in small pieces and share the pieces with other
peers to get other half of the file.
Online gaming services lets you play multiplayer games on the Internet via
broadband technology. As of this writing, your NBG4615 supports Xbox,
Playstation, Battlenet and MSN Game Zone.
