Abstract

When network services must be distributed over large geographic areas, it is essential to have an understanding of the telecommunication systems on which such distribution depends. One of the most significant differences between wide area networks (WANs) and local area networks (LANs) is the general dependency on third-party carriers to provide these transmission services. Whenever data is being sent across a WAN it must be routed between locations.
