Random Session Disconnects due to Spanning Tree Configuration
Scenario PCoIP sessions experience random session disconnects of some or all clients. Re connection is not always possible straight away.   Cause A Spanning Tree Protocol (STP) re-calculation can cause random session disconnects. STP will cause the …
Are there any limitations on physical distance for a PCoIP session?
Due to the design of PCoIP, using UDP for data transmission, PCoIP will operate over vast distances and network latencies up to 250 ms. PCoIP intelligently acknowledges the traffic inside the protocol allowing for high speed transmission over high latency …
What is the DHCP request timeout on a PCoIP Zero Client or PCoIP Remote Workstation Card?
The PCoIP Zero Client and PCoIP Remote Workstation Card will attempt to get a DHCP lease 4 times after power on or after the network link comes up. When a PCoIP device is connected to a network with no DHCP server and the DHCP request time-out period …
Why does my screen jitter or stutter, and scroll bars appear on the PCoIP Software client window after connecting to a PCoIP Remote Workstation Card?
Answer: This occurs when a software client is being used on a laptop with the display configured to operate in non-native mode. The EDID information found in some laptops only include timing information for the native display resolution. If a non-native …
What are my options for using PCoIP between trusted and untrusted networks?
PCoIP is encrypted by default and it cannot be disabled. This makes PCoIP itself secure on untrusted networks. To get PCoIP traffic from untrusted networks to PCoIP Hosts the following options can be used: Over a VPN that is UDP compatible. An SSL VPN …
How does competing traffic on the network affect PCoIP performance?
This article outlines how other types of network traffic may negatively impact PCoIP performance. Please refer to  Network session checklist for PCoIP protocol LAN and WAN deployments  for more details on network configuration. On most modern LAN's, …
What are the possible reasons for jitter on a 30 inch monitor when compared to a 24 inch monitor connected to the same Tera2 Remote Workstation Card?
Problem In a single workstation environment when comparing a 30 inch monitor at 2560x1600 to a 24 inch monitor at 1920x1600, moving a window containing a running video in the 30 inch screen shows latency and window drag when compared to the 24 inch …
How do I improve performance when dragging a window on the screen using firmware pre-4.1.0 and without a PCoIP Hardware Accelerator installed?
Problem While there are many factors that determine desktop performance - see  PCoIP TROUBLESHOOTING STEPS: VMware View Virtual desktop performance  - lower performance of window dragging may be observed in the following environment: VMware Horizon View …

Can I use an Ethernet hub or half-duplex network connection with a PCoIP Zero Client or PCoIP Remote Workstation Card?
No. PCoIP technology requires a full-duplex Ethernet connection from end to end. In modern networks, half-duplex links can still exist when using technologies such as Wi-Fi or point to point Wi-Fi or Microwave links. Older communication equipment in wired …
