11.3 RMON

RMON (Remote Monitoring) based on SNMP (Simple Network Management Protocol)

architecture, functions to monitor the network. RMON is currently a commonly used network

management standard defined by Internet Engineering Task Force (IETF), which is mainly used to

monitor the data traffic across a network segment or even the entire network so as to enable the

network administrator to take the protection measures in time to avoid any network malfunction. In

addition, RMON MIB records network statistics information of network performance and

malfunction periodically, based on which the management station can monitor network at any time

effectively. RMON is helpful for network administrator to manage the large-scale network since it

reduces the communication traffic between management station and managed agent.
