VMware View’s PCoIP over SSL VPN: UDP or TCP?
As today, VMware View Security Server provides support for RDP connection only. So it is necessary to leverage existing SSL VPN solutions to provide users with PCoIP like experience.
PCoIP is a server-centric protocol makes use of UDP datagrams, not TCP. Here you will find some good information about how the UDP protocol works.
The issue here is that most SSL VPN operates with TCP.
TCP is a connection oriented protocol and operates on port 443 just like standard HTTPS traffic, but being a TCP based tunnel, it will suffer from potentially poorer throughput because of the built in error checking. It will perform retransmission if there is an error detected in the 3-way handshake of the communication setup. Real-time traffic like VoIP, video and PCoIP streaming may suffer due to increased lag.
