Request for Comments, a series of notes about the Internet, submitted
to the Internet Engineering Task Force (IETF) and designated by an
RFC number, that may evolve into an Internet standard. The RFCs are
catalogued and maintained on the IETF RFC website: www.ietf.org/
rfc.html.
In 802.11, roaming occurs when a wireless device (a station) moves
from one Access Point to another (or BSS to another) in the same
Extended Service Set (ESS) -identified by its SSID.
Reverse Polarity-Subminiature version A, a type of connector used
with wireless antennas
Robust Security Network. A new standard within IEEE 802.11 to
provide security and privacy mechanisms. The RSN (and related TSN)
both specify IEEE 802.1x authentication with Extensible Authentication
Protocol (EAP).
RSSI received signal strength indication (in 802.11 standard)
RTS request to send, CTS clear to send (in 802.11 standard)
In Ethernet networks, a section of a network that is bounded by
bridges, routers or switches. Dividing a LAN segment into multiple
smaller segments is one of the most common ways of increasing
available bandwidth on the LAN.
Service Location Protocol. A method of organizing and locating the
resources (such as printers, disk drives, databases, e-mail directories,
and schedulers) in a network. Using SLP, networking applications can
discover the existence, location and configuration of networked
devices.
With Service Location Protocol, client applications are 'User Agents'
and services are advertised by 'Service Agents'. The User Agent issues
a multicast 'Service Request' (SrvRqst) on behalf of the client
application, specifying the services required. The User Agent will
receive a Service Reply (SrvRply) specifying the location of all services
in the network which satisfy the request.
For larger networks, a third entity, called a 'Directory Agent', receives
registrations from all available Service Agents. A User Agent sends a
unicast request for services to a Directory Agent (if there is one) rather
than to a Service Agent.
(SLP version 2, RFC2608, updating RFC2165)
Structure of Management Information. A hierarchical tree structure for
information that underlies Management Information Bases (MIBs), and
is used by the SNMP protocol. Defined in RFC1155 and RFC1442
(SNMPv2).
