Introduction To PCoIP

4

PCoIP – A Real-Time Protocol

Uses UDP packets – like other real-time protocols

• VoIP and Video Conferencing also use UDP

It’s “Bursty”

Easily affected by poor networking conditions

• Network Congestion – Limited Bandwidth

• High Latency

• Packet Loss

• End to End QoS/CoS

• Asymmetric Routing

• Burstable WAN’s – Committed Information Rate (CIR)

This is not an exact science

There is no right/wrong answer

It’s completely environment specific

NO

Optimizing Your Environment for PCoIP

12

Be Kind to Your Protocol

QoS/CoS

• Use sub-classification where possible

Congestion Control – WRED vs. Tail Drop

Minimize Latency

• Avoid deep buffers

• Minimize routing/hops

• Avoid in-line IDS/IPS

Beware of burstable circuits

Reach for the APEX

New and more demanding use case on existing hardware?

Consistent and high rate of pixel change?

Primarily full-screen multimedia?

3D – no, I mean REAL 3D?

Not a GPU!

What about Peripherals?

Well… It’s complicated

23

Simulate the Production Environment

24

Run a Pilot

Configure the Pilot as close to Production as possible!

• Make all applications available for testing

• Ensure resources are sized correctly

• Use the same endpoints

• Use the same peripherals

Calculate Bandwidth Requirements

37

Average vs Peak Average

Size for Average, but allow for Peak Average

1.25Mb/s

750Kb/s

Average Bandwidth = 200Kb/s

Peak Average = 1Mb/s

Summary

Optimize your environment, then tune the protocol – know your

“PCoIP” use case

Simulate the Production environment to get more accurate results

Measure from multiple sources before sizing

Size your networks to allow for PCoIP bursts
