PCoIP (PC over IP) is a display protocol developed by Teradici. Its purpose is to transmit the display content via LAN and WAN.
The PC over IP technology is based on UDP (User Datagram Protocol) which is an alternative to TCP (Transmission Control Protocol). With UDP no acknowledge occurs after the transmission of a data package in contrast to the TCP. This is the only way to achieve an optimum performance.
PCoIP transmits display pixel content by coding them onto an external host. Afterwards the data is streamed onto the client. In doing so, only the regions of the display that are changed frame by frame are being transmitted. This means that the whole display content will never be transmitted. For a client it seems as if he´s watching a movie on the desktop. That is being generated in real time depending on the activity. Even though it is increasing the CPU usage on the remote host, PCoIP is also able to deal with multimedia data and graphics-intensive applications.
PCoIP recognizes the available data transmission speed independently and runs the necessary adjustments of the protocol. Thereby PCoIP can be operated via WAN perfectly.
PCoIP is implemented in the Tera2 chip for the Zero Client and the workstation host card. If the VMware Horizon View or Workstation Access Software is used, the PCoIP protocol is “moulded” into software.
For accessing the cloud it is not essential to use a Zero Client – whereby the Zero Client is offering the optimal quality. If you´re content with a “lighter” version, the solution is also provided by a software solution client-side.
VMware is offering the VMware client for VMware Horizon view and Teradici is offering the PCoIP Software Client for the Remote Workstation host card and the Workstation Access Software. To access the cloud environment in general you can also use the required Apps for IOS and Android.
