    Hello 3 questions,

    1. how does Lync establish connections between clients.  My understanding is that pc1 IM's pc2, this is peer to peer.  Ad in pc3 and this moves to the front end server.  this correct?  What about conferencing, is it peer to peer or all hosting off of the front end?  If you are sharing a powerpoint in a meeting, does that get download to all or just on the pc and people can download if they want?

    2. bandwidth for IM and conferencing.  I was trying to find an idea of how much bandwidth is required for Im and conferencing, we are not doing audio/video.

    3.  Are there any QoS polices out yet for IM or conferencing, is it needed?  

    Thanks,

    Hi,

    1. how does Lync establish connections between clients.  My understanding is that pc1 IM's pc2, this is peer to peer.  Ad in pc3 and this moves to the front end server.  this correct?  What about conferencing, is it peer to peer or all hosting off of the front end?  If you are sharing a powerpoint in a meeting, does that get download to all or just on the pc and people can download if they want?

    Yes, you are  right. When you initiate a IM chat to another one client, it is peer to peer. If the third client joins in the chat, the chat will be escalated to group conferencing and created on Lync FE server. If you share a powerpoint in meeting, everyone in the meeting can download the file.

    2. bandwidth for IM and conferencing.  I was trying to find an idea of how much bandwidth is required for Im and conferencing, we are not doing audio/video.

    Compare with audio/video, the IM need very less bandwidth. I think you need not to take care about the bandwidth for IM and conferencing(without a/v). If the conferencing includes application sharing, please know the bandwidth of application sharing in the following article:http://technet.microsoft.com/en-us/library/gg425781.aspx

    3.  Are there any QoS polices out yet for IM or conferencing, is it needed? 

    Looks like There is no any Qos policy for IM, and it isnot needed. About conferencing, there are a\v QOS policies to it.
