connection using NAT technology. A wireless router is a device that combines the
functions of wireless Access Point and the IP sharing router.
RSSI
Receiver Sensitivity Index. RSSI is a value to show the Receiver Sensitivity of the remote
wireless device. In general, remote APs with stronger signal will display higher RSSI
values. For RSSI value, the smaller the absolute value is, the stronger the signal. For
example, “-50db” has stronger signal than “-80dB”. For outdoor connection, signal
stronger than -60dB is considered as a good connection.
RTS
Request To Send. A packet sent when a computer has data to transmit. The computer will
wait for a CTS (Clear To Send) message before sending data.
RTS Threshold
RTS (Request to Send). The RTS/CTS(clear to send) packet will be send before a frame
if the packet frame is larger than this value. Lower this value can improve the
performance if there are many clients in your network. You can try 1500, 1000 or 500
when there are many clients in your AP’s network.
SNMP
Simple Network Management Protocol. A set of protocols for managing complex
networks. The SNMP network contains 3 key elements: managed devices, agents, and
network-management systems (NMSs). Managed devices are network devices that
content SNMP agents. SNMP agents are programs that reside SNMP capable device's
firmware to provide SNMP configuration service. The NMS typically is a PC based
software such as HP Openview that can view and manage SNMP network device remotely.
SSL
Secure Sockets Layer. It is a popular encryption scheme used by many online retail and
banking sites to protect the financial integrity of transactions. When an SSL session
begins, the server sends its public key to the browser. The browser then sends a randomly
generated secret key back to the server in order to have a secret key exchange for that
session. SSL VPN is also known as Web VPN. The HTTPS interface use SSL for data
encryption.
