RTP typically runs on top of the UDP protocol, but can support other transport
protocols as well.
RTS
A request to send (RTS) message is a signal sent by a client station to the access
point, asking permission to send a data packet and to prevent other wireless client
stations from grabbing the radio waves. This message is a part of the IEEE 802.11
CSMA/CA protocol. (See also RTS Threshold and CTS.)
RTS Threshold
The RTS threshold specifies the packet size of a request to send (RTS) transmission.
This helps control traffic flow through the access point, and is especially useful for
performance tuning on an access point with a many clients.
S
Shared Key
A shared key is used in conventional encryption where one key is used both for
encryption and decryption. It is also called secret-key or symmetric-key encryption.
Also see Public Key.
SNMP
The Simple Network Management Protocol (SNMP) was developed to manage and
monitor nodes on a network. It is part of the TCP/IP protocol suite.
SNMP consists of managed devices and their agents, and a management system.
The agents store data about their devices in Management Information Bases (MIBs)
and return this data to the SNMP management system when requested.
SSID
The Service Set Identifier (SSID) is a thirty-two character alphanumeric key that
uniquely identifies a wireless local area network. It is also referred to as the Network
Name. There are no restrictions on the characters that may be used in an SSID.
