They are used to connect local computers, peripherals, and other devices within a single building or other small geographic area. • Are WANs Necessary? • Without WANs, LANs would be a series of isolated networks. • LANs provide both speed and cost-efficiency for transmitting data over relatively small geographic areas. • However, as organizations expand, businesses require communication among geographically separated sites. • The following are some examples where we need wan. • Regional or branch offices of an organization need to be able to communicate and share data with the central site or HQ. • Employees who travel on company business frequently need to access information that resides on their corporate networks. • WAN Topologies • Interconnecting multiple sites across WANs can involve a variety of service provider technologies and WAN topologies. • There are four Common WAN topologies. • Point-to-point topology -:•Employs a point-to-point circuit between two endpoints • Hub-and-spoke topology -:•Applicable when a private network connection between multiple sites is required • Full mesh topology -:•With a full mesh topology using virtual circuits, any site can communicate directly with any other site. • Dual-homed topology -:•Provides redundancy and load balancing however they are more expensive to implement than single-homed topologies. • WAN technologies are either • Circuit-switched-: Such as PSTN or ISDN • Packet-switched. -:MPLS,Metro Ethernet WAN, ATM, or Frame Relay. • #wan #CCNA #freetraining #netowork
