A brief analysis of Remote Desktop Protocol (VNC/SPICE/RDP)

Because the recent project involves virtual desktop, it took a bit of time to find a bit of information to look at the current commonly used protocols have VNC/SPICE/RDP three kinds, here do a simple introduction.

Comparison of three types of protocols

	SPICE	Vnc	Rdp
BIOS Screen Display	Yes	Yes	No
Full color support	Yes	Yes	Yes
Change resolution	Yes	Yes	Yes
Multi-Monitor	Multi-monitor support (up to 4 images)	Only one screen	Multi-monitor support
Image transmission	Image and graphics transmission	Image transmission	Image and graphics transmission
Video playback Support	GPU Acceleration Support	No	GPU Acceleration Support
Audio transmission	Bidirectional voice can be controlled	No	Bidirectional voice can be controlled
Mouse control	The client server can control	Server-side control	Server-side control
USB transfer	USB can be transmitted over the network	No	USB can be transmitted over the network

First, VNC

Applicable systems: Windows, Linux

Network traffic: Small, commonly used around 100k

Application scenario: The management of the server mainly used for Linux, due to no sound and USB transmission, not satisfied with the use of virtual desktop

# Install yum install tigervnc-   Server#VNC server startup vncserver   # View Connection vncserver  -list  # Modify access password vncpasswd     # Close vncservervncserver-kill : N

Configuration file Modification

#vim/etc/sysconfig/vncservers  #  vncservers= "2:myusername"   Sessionnumber, user name # vncserverargs[2]= "-geometry 800x600-nolisten tcp-localhost"vncservers=" 1:root " # display port and username vncserverargs[1]="-geometry 800x600-nolisten tcp-nohttpd"

Second, SPICE

Applicable system: Linux

Network traffic: Large, normal use 10-20m

Application scenario: For virtual desktops, primarily for virtual desktops, in color, audio, and USB

Use: After installation, you need to configure in the virtual machine, refer to my blog about the virtual machine.

Third, RDP

There are currently two types of RDP on Windows, Remote,remotefx

Applicable systems: Windows, Linux

Network traffic: Small, normal use 100-200k around

Scenario: Ideal for virtual desktops due to better color, audio, USB and local disk mapping

Windows uses: It can be used after the system is installed.

# install Rdesktop on Linux for Linux access WINDWS Remote Desktop # installation Yum Install rdesktop # If you need to install it on the interface Yum Install tsclient # use command-line access,-f full Screen-color-c L Connection type  - 119.0. 0.100:1234

# accessing Linux using the RDP protocol Yum Install xrdp # start the XRDP service XRDP
