|
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 |
|

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 |
