Quality of Service (QoS)
QoS refers to the capability of a network to provide better service to selected
traffic flows using features such as data prioritization, queuing, congestion
avoidance and traffic shaping. These features effectively provide preferential
treatment to specific flows either by raising the priority of one flow or limiting the
priority of another flow.
Remote Authentication Dial-in User Service (RADIUS)
RADIUS is a logon authentication protocol that uses software running on a
central server to control access to RADIUS-compliant devices on the network.
Remote Monitoring (RMON)
RMON provides comprehensive network monitoring capabilities. It eliminates the
polling required in standard SNMP, and can set alarms on a variety of traffic
conditions, including specific error types.
Rapid Spanning Tree Protocol (RSTP)
RSTP reduces the convergence time for network topology changes to about 10%
of that required by the older IEEE 802.1D STP standard.
Secure Shell (SSH)
A secure replacement for remote access functions, including Telnet. SSH can
authenticate users with a cryptographic key, and encrypt data connections between
management clients and the switch.
Simple Mail Transfer Protocol (SMTP)
A standard host-to-host mail transport protocol that operates over TCP, port 25.
Simple Network Management Protocol (SNMP)
The application protocol in the Internet suite of protocols which offers network
management services.
Simple Network Time Protocol (SNTP)
SNTP allows a device to set its internal clock based on periodic updates from a
Network Time Protocol (NTP) server. Updates can be requested from a specific
NTP server, or can be received via broadcasts sent by NTP servers.
