Using RADIUS, you must enter your user name and password before gaining access to a network. This
information is passed to a RADIUS server, which checks that the information is correct, and then authorizes
access. Though not an official standard, the RADIUS specification is maintained by a working group of the
IETF.

Resource Reservation Setup Protocol

RSVP is a new Internet protocol being developed to enable the Internet to support specified
Qualities-of-Service (QoS). Using RSVP, an application will be able to reserve resources along a route from
source to destination. RSVP-enabled routers will then schedule and prioritize packets to meet the
prioritization assigned by QoS. RSVP is a chief component of a new type of Internet being developed,
known broadly as an integrated services Internet. The general idea is to enhance the Internet to support
transmission of real-time data.

RFC

The Requests for Comments (RFC) document series is a set of technical and organizational notes about the
Internet. The official specification documents of the Internet Protocol suite that are defined by the Internet
Engineering Task Force (IETF) and the Internet Engineering Steering Group (IESG) are recorded and
published as standards track RFCs.

router

A device that forwards data between networks. An IP router forwards data based on IP source and
destination addresses.

RMON

Short for remote monitoring, a network management protocol that allows network information to be
gathered at a single workstation. Whereas SNMP gathers network data from a single type of Management
Information Base (MIB), RMON 1 defines nine additional MIBs that provide a much richer set of data about
network usage. For RMON to work, network devices, such as hubs and switches, must be designed to
support it. The newest version of RMON, RMON 2, provides data about traffic at the network layer in
addition to the physical layer. This allows administrators to analyze traffic by protocol.

Simple Network Management Protocol

SNMP is the protocol governing network management and the monitoring of network devices and their
functions. It is not necessarily limited to TCP/IP networks. The versions have the following differences:

SNMPv1 (full): Security is based on community strings.
