Hierarchical performance management using OAM MIB in ATM networks

As the network grows bigger and faster, the demand for reliable and rapid network monitoring and control is on the increase. For efficient network performance management, the network manager should be able to not only acquire the overall network status information with minimum management traffic, but also immediately figure out the faulty network elements. We propose a hierarchical performance management scheme with operation and maintenance (OAM) management information base (MIB) by using the SNMP management protocol. With this MIB we can remotely monitor each connection and pinpoint the location of a performance problem.
