Pcoip vs ICA Protocol Comparison

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
