Pcoip vs ICA Protocol Comparison

Source: Internet
Author: User

A comparison of the remote protocols used by VMware view and Citrix xendesktop is found online.
The differences between the two protocols are analyzed from multiple perspectives. I personally think it is a comprehensive comparison document.

Pcoip vs ICA Protocol

Virtual desktop requirements

View pcoip (UDP)

Xendesktop ICA (TCP)

Description

Functionality

Environmental Adaptability

Network Packet Loss, latency, and jitter

Supported

Not Supported

Pcoip supports a latency of 250 ms, and ICA does not support a latency of 150 ms.

Performance

1,
Each connection requires three handshakes confirmed by both parties before data transmission.

2,
TCP packet encapsulation is more complex than UDP, with many fields and complicated headers.

3,
After the data packet is transmitted, it must be verified before the subsequent data is transmitted.

High

Low

UDP connections do not require negotiation, data packet encapsulation is simple, with few fields, simple headers, and fast transmission speed.

Security

1,
TCP connection itself is prone to SYN flood attacks

No

Yes

2,
TCP and UDP do not have data encryption. The software protocol itself needs to provide data encryption (128bit)

Yes

Yes

Display

Supports multiple monitors

4

2

32-bit true color

Supported

Supported

ICA is only supported in xendesktop5

High Resolution Support

2560*1600

1600*1200

1600*1200 is the maximum value.

Large Screen Size support

Yes

Limited

Data Transmission Mode

Only screen refresh, mouse, keyboard, and differential data are transmitted.

Yes

Yes

Protocol subchannel Division

You can divide the keyboard, mouse, print, scan, multimedia, and screen sub-channels...

Yes

Yes

Controllable sub-channel

Enable or disable the service to save bandwidth.

Yes

Yes

Multimedia Content Acceleration and requirements

Support for different multimedia modes and formats

All

Part

ICA only supports files in specific media formats and has a high degree of matching for multimedia software versions.

IsV Authentication

OEM hardware vendor and isV for remote protocol authentication

Supported

Not Supported

Pcoip has been certified by many software vendors, such as Dassault systemes (Catia, SolidWorks ),
Autodesk (3 dstudiomax, softimage), Siemens-UGS (NX, SolidEdge ),

Schlumberger (Petrel, geoframe ),

Data Compression and caching

1,
Data can be compressed and pre-cached.

2,
Network device performance overhead

3,
Additional hardware products are required

No

Support from other hardware devices

To achieve a good experience, ICA needs to use other network hardware products, while UDP itself provides good data transmission performance.

Multimedia Content redirection

Automatically determine the decoding and rendering location for multimedia content

Automatic

Hard setting (not flexible)

ICA can only hard adjust the location (client or server)

Adaptive transmission quality

Automatically determines the network quality and bandwidth, and promptly adjusts the data transmission priority,
Dynamically adjust image quality and Frame Rate

Automatic

Hard setting (not flexible)

ICA can only make judgments based on predefined policies, but cannot be fully adaptive.

Client Support

Inside and outside China

Foreign

More than 450 devices support pcoip, while only a few vendors of ICA
Supported
