WAN Switching
Discuss the types of switching expected to be found on a WAN. How do the different types of switching in a WAN influence the security of transmission? Comment on variations and the availability of the tools to help with the implementation of security measures.
According to the Internet search definition archive Webopedia, a WAN or wide area access network is a type of computer network that spans a relatively large geographical area. Typically, a WAN consists of two or more computer networks or LANs, local area access networks www.webopedia.com/TERM/W/local_area_network_LAN.html." Computers connected to a wide-area network are often connected through interconnected public networks, such as the telephone system, or through dial-up connections. These WANs can also be connected through leased lines or satellites. The largest WAN in existence is the Internet, but smaller WANs such as within geographical areas of cities, companies, or university complexes or between academic areas can exist.
Leased lines, unlike dial-up connections, are always active. Such cable or broadband connections tend to be faster than dial-up connections but they are not necessarily more secure. Applying bandwidth management, application layer monitoring,...

For instance, the use of remote office storage and caching appliances can be used to eliminate remote file servers, storage and back-up devices from branch offices, while boosting performance of centrally hosted Unix-, Linux- and Windows-based applications. Such efforts can also increase security, as diminishing…
