While reading this answer the one thing that I wish this one had was some relevant options that use the 3 cases. I'd like to emphasize the fact that VNC is simply a horrible comparison point.

Cisco acquired Webex Communications in Aimed to help organizations and individuals conduct online training and web conferencing, it integrates seamlessly with Outlook for convenient scheduling and enables real-time access to screen sharing.

A great alternative to TeamViewer, Webex Remote makes it easy to transfer files, keep pace with regulatory changes, and manage company software, thereby reducing maintenance delays. With its free version , users can hold online meetings with up to two other participants. Premium packages will grant access to additional features, such as password protection, setting up web conferences with as many as guests, screen-sharing, and personalized user profiles and permissions.

LogMeIn Pro provides 1TB of cloud space to store relevant files, applications, and projects in one centralized place. While this TeamViewer alternative only allows access to a cap of ten computers, an unlimited number of users can access these files in the cloud. Additionally, it uses Public Key Infrastructure to verify the identity of both the server and the host. Users can try out these features with a day trial before committing to a paid version.

With both free and paid versions, VNC Connect may appeal more to small businesses. It holds a security advantage with its password-protected bit AES encryption and two-factor authentication. Users will appreciate the high-speed streaming for remote access across cloud and offline connections.

While its strength lies in its security, VNC Connect unfortunately lacks web conferencing features. However, its paid version gives enterprises comprehensive control over unlimited devices and standard features like data transfer and chat. Remote work is rapidly becoming the norm. As mentioned earlier, TeamViewer has consistently been a popular tool, but these alternatives offer expanded capabilities to propel businesses and individuals into the future of remote access and IT support.

I'm at this level. And they use something called the RFB protocol. I heard, from somewhere on StackOverflow, that Windows Remote Desktop doesn't send screen bitmaps, but actual drawing commands. That's quite brilliant, because it can just send simple text draw this rectangle at this coordinate and color it with this gradient!

Remote Desktop really is pretty fast - and it's the standard way of working from home. And it uses something called the RDP protocol. Now TeamViewer is a complete mystery to me. Apparently, they released their source code for Version 2 TeamViewer is Version 7 as of February But Version I mean, it's actually faster than Windows Remote Desktop. By the way, TeamViewer does all this without a mirror driver. There is an option to install one, and it gets just a bit faster.

My question is, how is TeamViewer so fast? It must not be possible. If you've got by resolution at even 24 bit depth 16 bit depth would be noticeably ugly , thats still 6,, bytes raw. Even using libjpeg-turbo one of the fastest JPG compression libraries used by large corporations , compressing it down to 30KB let's be extremely generous , would take time to route through TeamViewer's servers TeamViewer bypasses corporate Symmetric NATs by simply proxying traffic through their servers.

And that libjpeg-turbo compression would take time to compress. High-quality JPG compression takes milliseconds for a full by screenshot for me. And that number goes up if the host's computer runs an Atom processor. I simply don't understand how TeamViewer has optimized their screen transfer so well. Again, small-size images might be highly compressed, but take at least tens of milliseconds to compress.

Large-size images take no time to compress, but take a long time to get through. Somehow, TeamViewer completes this entire process to get roughly frames per second. I've used a network monitor, and TeamViewer is still lagless at speeds of Kbps and 1 Mbps VNC software lag for a few seconds at that transfer rate. During my tree Command Prompt test, TeamViewer was receiving inbound data at a rate of 1 Mbps and still running fps. VNC and remote desktop don't do that.

So, how? The most fundamental thing here probably is that you don't want to transmit static images but only changes to the images, which essentially is analogous to video stream. My best guess is some very efficient and heavily specialized and optimized motion compensation algorithm, because most of the actual change in generic desktop usage is linear movement of elements scrolling text, moving windows, etc.

You'll find that TeamViewer rarely needs to relay traffic through their own servers. They do use their own servers to middle-man in order to do the handshake and connection set-up, but most of the time the relationship between client and server will be P2P best case, when the hand-shake is successful. It sounds indeed like video streaming more than image streaming, as someone suggested. Imagine having a recording codec on your system that can realtime record an incoming video stream your screen.

A bit like Fraps perhaps. Then imagine a video playback codec on the other side the remote client. As HD recorders can do it record live and even playback live from the same HD , so should you, in the end. The HD surely can't deliver images quicker than you can read your display, so that isn't the bottleneck.
