Suppose a company is a parent company having two branch offices in the same city and two other offices in two different cities. Which is the most economical and suitable form of set up. Should one go for standard LAN config or go for lease lines for both local and remote machines.
It depends on the number of users per office. If you have less than 20 users per office you may be able to use DSL and connect the offices through VPN links. This is less reliable but is cheaper.
If you want a robust network you can get leased lines but the cost is based on distance and it will cost you more than DSL. However you can run VOIP and other services over ISDN.
