Vat is an audio conferencing application developed by the group Research Network Lawrence Berkeley National Laboratory. The source code and precompiled binaries are available by anonymous FTP. The LBNL audio tool, VAT is a real time multi-party, multimedia application for audio conferencing over the Internet. The VAT is based on the draft standard Internet Real-time Transport Protocol (RTP) developed by the IETF Audio / Video Transport Working Group. RTP is an application level protocol implemented entirely within the VAT - you do not need special system enhancements to run RTP. Although the VAT can be run point to point using standard unicast IP addresses, it is primarily designed as a multiparty conferencing application. To use the conferencing capabilities, your system must support IP Multicast, and ideally, your network should be connected to IP multicast backbone (MBone).
