Local web for network diagrams?

Question

Computer networks

Good afternoon!
Can someone tell me if there is a web product for deployment within an organization, in which you can draw network diagrams? Maybe some flowchart editor...
What are the requirements:
1. Web interface, and only local deployment.
2. Ability to restrict access
3. History of saves and changes.
A plus would be free, and the ability to upload in vsd format.
Thanks!"
