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 environment is known to have multiple routers congested in a given path, then the network queue size should be adjusted (i.e. 30-50ms per network device if two network devices are expected to be congested at a given time). 

Note: The accumulative latency and network device queues of both sending and receiving needs to be taking into account when setting buffer sizes. The total PCoIP session latency should not exceed 250ms but the higher the latency the lower the user experience. 

Note: The network buffer size is specified in milliseconds. Not all network devices support this setting a time and may require a packet count. PCoIP is comprised of large and small packets generated based on user actions. In this scenario a best guess would be required and further monitoring and tuning.
