Help me for programming sockets in vb.new

hi this is parth,
i m develping an application that sends a text message with a voice
file(wav).. I know it using TCP protocol but i wanna use IGMP or RDM
protocol type directly using the socket class....
TCP is connection oriented so it's easy to send n receive large(300
kb) voice files to/from large number of users and manage them..
but in UDP multicaste how can i manage identify which packet from
which user?...
any example using sockets
like
dim soc = new
Socket(AddressFamily.InterNetwork,SocketType.Rdm,P rotocolType.Igmp)...

any reply will b appreciated...
thanks...
