DNS Domain Name System. An Internet service that translates domain names into IP

addresses. Domain names are a clear way of representing an Internet address.

The Internet, however, is actually based on IP addresses. For example, the URL

http //www.website.com might actually point to the IP address http

//123.456.789.0. Because maintaining a central list of domain name/IP address

correspondences would be impractical, the lists of dom ain na mes an d I P

addresses are distributed throughout servers on the Internet in the Domain N ame

System. If one DNS server cannot translate a particular domain name, it contacts

another one, and so on, until the correct IP address is retu rned.

DTIM Deliver Traffic Indication Message. Used by access points to tell power-save

client devices that a packet is waiting for them.

DSCP Differentiated Services Code Point is a model in which traffic is treated by

intermediate systems with relative priorities based on the type of services.

EAP-MD5 server Servers running extensible authentication protocol to provide dynamic,

session-specific wireless encryption keys, central user administration. and

authentication between clients and access points. EAP-MD5 uses MD5 hashin g

on client and challenge passwords. The WLSE monitors EAP-MD5 servers.
