WAN Technologies
All of the WAN technologies can be
categorized in dedicated and switched variants. The preferred and optimum
technology of WAN construction is the mode of switching of packets.
However, frequently switching mode appears inaccessible in a specific
widespread geographical region. Nevertheless, under the circumstances
it is most likely then an area with widely distributed services by telephone
networks or networks with dedicated phone lines that is already established
and supporting the WAN structure. Therefore a combination of both technologies
switch and dedicated allows to build a corporate network by combining
both ways WAN is operating.
