VMware View Mobile Secure Desktop Bootcamp Day 8 PCoIP

VMware View Mobile Secure Desktop Bootcamp – Day 8

PCoIP Optimzation

Real-protocol – like VoIP
Host-based pixel encoding – onlyl change pixels are sent
UDP based – no TCP overhead, app layer reliability

PCoIP Protocol Features
“Build to lossless” – lower quality updates on images in motion until static
Utilizes multiple codec dependig on content
Adaptive bandwidth consumption – uses as much bandwidth as possilbe
Client side caching of frequent data
WMI session monitoring

Text Codec
– Lossless text
– Increased compression on ClearType
– 10-20% bandwidth savings

Disable Build-to-lossless
– Build to “preceptually” lossless, cant tell for most use cases
– 10-15% bandwidth savings

Client-Side Caching
– Store frequent content on endpoint
– Sends ‘address’ and ‘location of content
– 30-40% bandwidth savings

PCoIP Monitoring tools
– Lakeside SysTrack
– Liquidware Labs
– Xangati

Free
– Perfmon
– PCoIP Log Viewer

SSL VPN encaps UDP in TCP packets, lose UDP benefits
Bypass WAN acceleration and IDS/IPS

Avoid usecases with round trip 300ms latency

No per-packet load balancing, enable stickiness
Use VM optimization guides for visual settings

PCoIP Tunable Parameters in pcoip.adm via GPO or registry

Build to lossless set to enable in GPO + accept checkbox, 0 via registry
Client-side cache enable with cache size

When to tune
– Best practices first
– network sized/configed
– optimize desktop image
– PCoIP already adapts
– Reduce bandwidth = impact user experience

Disable build-to-lossless
Config max session bandwidth
Config session floor when..
– experiencing packet loss but network has availability
– packetloss on WiFi or 3g/4g
Config max frame rate
Config max initial image quality
Config min image quality
Config audio bandwidth limit
Config client-side cache
