What is an Enterprise Network?

As seen from the diagram,
  • The office network would have desktops/laptops, lot of servers like file servers, mail servers, web servers etc. One or more L2 switches provide connectivity between these end stations. 
  • Employees, working from home, would typically access the office network via.  a Remote Access Server(RAS). The RAS would primarily authenticate the remote end stations before allowing access to the office network.
  • The office network would use a gateway router to connect it to the public data network (internet).
Enterprise networks could even  be spread across multiple geographical locations connected together by private leased lines
