Introduction to Screen Sharing Screen sharing is important in
many CSCW applications. AT&T Virtual Network Computing (VNC),
Microsofts Remote Desktop Protocol (RDP), Apple Remote Desktop
(ARD) to perform remote administration. Also in MSN Messenger,
Adobe Connect, Skype, WebEx, Vsee & etc for participants to
share contents.
Slide 4
Scaling CSCW Collaboration With bandwidth increase,
collaboration technologies has been increasingly complicated.
Involves more and more participants. Number of connection
increase.
Slide 5
Screen Sharing Modes 1 to 1 Typical screen sharing. 1 to * Does
not scale more than 5-10 participants. Need to duplicate same
packet to all nodes. * to * Consume tremendous network resources if
packet duplication is required for all nodes. Latency is important
factor in CSCW!
Slide 6
Problems with current approach To scale, improve performance
such as TightVNC. Most systems are designed for unicast
connectivity. Suitable for sharing with 1 person up till about 10
on a single media. Attempt to improve with multicast screen
sharing. Benefit of multicast: Nb
