PCoIP PC-Over-IP Intro

Sharing is caring!

PC-over-IP is display protocol that allows complete compression of display over standard IP network “desktop virtualization “.  It allows enterprise desktops to be centrally located and managed in the data centre while providing the remote user with an exceptional experience. Three of the main commonly used  display protocols exists in desktop virtualization such as RDP, ICA and RGS. Some endpoint types, like Zero clients, support only a subset of display protocols.

The choice of display protocol will heavily influence the way the network is configured, the amount of computation power required, policy application, future compatibility and most importantly, the user experience. PCoIP has been adopted by VMware as one method of up selling the value of VMware’s virtualization solutions over its two main competitors, Microsoft (using RDP and RemoteFX) as well as Citrix (using Xen Desktop and HDX). RemoteFX (MSFT) and HDX (Citrix) are software only approaches to graphics acceleration that “compete” with PCoIP.

PCoIP uses the UDP protocol which is much better suited for streaming media and display. UDP (User Datagram Protocol) is not concerned with how the data ends up on the receiving end, it’s only concerned with speed, this is why streaming media is sometimes not good quality. The PCoIP protocol compresses, encrypts and encodes the entire computing experience at the data centre and transmits it ‘pixels only’ across any standard IP network to stateless PCoIP zero clients. Your data never leaves the data centre. All the host has to do is transmit the pixels via the IP network to the zero client which receives the pixels and decodes them to display your desktop image

PCoIP solutions can be used to provide hardware acceleration to offer near perfect application performance for high end graphics applications (video editing, engineering cad-cam, video training, flash applications. It supports high resolution, full frame rate 3D graphics and HD media, multiple large displays, full USB peripheral connectivity, and high definition audio, all connected over the corporate LAN or WAN.
When configuring a PCoIP Secure Gateway, one must keep in mind that the gateway uses port 4172 for remote console connection while the USB traffic is diverted through port 443 for VMware View Clients. Thin Clients use port 4172 for all communication. Connections from the outside on port 443 (TCP) and 4172(TCP, UDP) mustbe open. When using the Security Server as the PCoIP Secure Gateway in a DMZ, the firewall must be configured so that the Security Server can connect to all the View desktops on port 4172 and 3211
