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 …
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 network switch or router queue size should be used?
Network device queues, also known as network buffer's, should be configured to accommodate 50ms to 100ms of PCoIP protocol traffic in total. This assumes that one network device (e.g. switch or router) is congested for a given network path. If the network …
What is the impact of minimum and maximum initial image quality on a PCoIP Session?
Minimum and maximum initial image quality sets the lower and upper quality level. The default values in HP Anyware is Q40 for the minimum initial image quality and Q80 for the maximum initial image quality. If PCoIP estimates there is adequate bandwidth …
Should I use an initial image quality of Q100?
An initial image quality of Q100 will deliver the highest quality of image PCoIP can deliver. Q100 is not lossless, for a lossless image, build to lossless must be enabled.  How to configure the Turn off Build-to-Lossless feature session variable in GPO …
How does device discovery work with the PCoIP Management Console 2.x and 3.x?
The PCoIP Management Console must discover all of the PCoIP devices that it manages and therefore supports the discovery of devices using three mechanisms: DHCP Option discovery DNS DNS Service Record Discovery DNS-Based Discovery Prefix Manual Discovery …
Can a WAN accelerator be used to improve the performance of PCoIP sessions?
PCoIP does not benefit from a WAN accelerator, legacy WAN accelerator solutions use different methods to improve the performance of applications operating over congested networks. These methods include compressing packets, implementing proxy servers that …
PCoIP Management Console 2.x and 3.x is not loading pages properly when accessing the web interface via the FQDN
Problem Using fully qualified domain name (FQDN) in your browser to access the PCoIP Management Consoles web interface displays only a portion of the page. Using the IP address, the web interface page is displayed properly and user is prompt for user name …
What does "IPC: Frame encode took xxx ms so far. Dropping down the quality to index x." in the log files indicate?
Answer: In this case, the imaging encoder has determined that too many bits were being sent in the upper portion of the frame (i.e. flooding) which causes the frame to take longer to encode, and therefore appears unresponsive to the user (> 750 ms to …
