Differentiated Services Code Point (DSCP) A system of assigning Quality of Service "Class of
Service" tags.
Domain Name Service (DNS) A standard methodology for converting alphanumeric Internet
domain names to IP addresses.
Dynamic Host Configuration Protocol (DHCP) A communications protocol enabling IP address
assignments to be managed both dynamically and centrally. With DHCP enabled
on a node (a system, device, network card, or access point), when it boots or is
connected to a network, an address is automatically assigned. Each assigned
address is considered to be "leased" to a specific node; when the lease expires, a
new IP can be requested and/or automatically reassigned. Without DHCP, IP
addresses would need to be entered manually for each and every device on the
network.
dynamic IP address A TCP/IP network address assigned temporarily (or dynamically) by a
central server, also known as a DHCP server. A node set to accept dynamic IPs is
said to be a "DHCP client."
Extensible Authentication Protocol (EAP) Standard that specifies the method of
communication between an authentication server and the client, or supplicant,
requesting access to the network. EAP supports a variety of authentication
methods.
Extensible Authentication Protocol Over LAN (EAPOL) Protocol used for 802.1x
authentication.
EAP-TLS EAP using Transport Layer Security. EAP-based authentication method based on
X.509 certificates, which provides mutual, secure authentication. Certificates
must be maintained in the authentication server and supplicant.
EAP-PEAP Protected EAP-based authentication method based on X.509 certificates. Uses a two-
phase approach in which the server is first authenticated to the supplicant. This
establishes a secure channel over which the supplicant can be authenticated to the
server.
Extended Service Set (ESS) A set of multiple connected BSSes. From the perspective of
network clients, the ESS functions as one wireless network; clients are able to
roam between the BSSs within the ESS.
ESSID Name or identifier of the ESS used in network configuration.
hostname The unique, fully qualified name assigned to a network computer, providing an
alternative to the IP address as a way to identify the computer for networking
purposes.
Hypertext Transfer Protocol (HTTP) Protocol governing the transfer of data on the World Wide
Web between servers and browser (and browser enabled software applications).
Hypertext Transfer Protocol over SSL (HTTPS) A variant of HTTP that uses Secure Sockets
Layer (SSL) encryption to secure data transmissions. HTTPS uses port 443,
while HTTP uses port 80.
