The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

VPN 3DES Encryption.  What kind of bandwidth overhead comes with this encryption scheme?

Asked by KrAzY in Virtual Private Networking (VPN)

Tags: , ,

I currently have ADSL through a company, 1436Kbs Download/256Kbs Upload.  I am currently using a VPN solution with 3DES encryption.  I have this ADSL VPN 3DES Encryption DSL Modem/Router at my office.  When I connect to it fromhome, using drive/folder mappings or VNC it is Extremly Slow.  If I use Windows Remote Desktop without the VPN and turn all the Remote Desktop settings to low, the session isn't so bad.  I am wondering how much overhead this 3DES encryption might have, being that my upload speed is 256Kbs.  Another thing is that I purchase this VPN solution from a DSL provider, and their solution is so you can have teleworkers and other VPN Remote locations (VPN Router to VPN Router).  I am starting to think this not a viable situation:

3DES overhead.
Multiple Teleworkers and/or Multiple VPN locations.
Possiblility of people behind VPN router using up/down bandwidth.

All limited to 256Kbs.

Ok, the bandwidth is NOT their for someone to do what is listed above.  I guess I am just more curious about the bandwidth overhead of 3DES, and how it would play along with a remote desktop application such as VNC.

Thanks,
