PMI-110-F2G also supports advanced Ring technology – M.S.R. (Multiple Super Ring) which
includes various new technologies for different network redundancy applications and
structures. The supported MSR allows PMI-110-F2G aggregating up to 5 Rapid Super rings
includes 4 Fast Ethernet plus 1 Gigabit Ethernet rings into one switch. With the MSR technology,
a node can be configured to multiple rings with the failover time. In addition, users can extend
the ring topology by adding hundreds of PMI managed switches to meet the large-scale
network needs without compromising the network speed. The MSR also allows PMI-110-F2G
managed switch to easily connect with core management switches via standard Rapid Spanning
Tree Protocol (RSTP) or through multiple paths or nodes to increase the reliability by RDH (Rapid
Dual Homing) technology. By integrating MSR and LACP (Link Aggregation Control Protocol), the
PMI series can enhance the link ability and increase the overall link capacity. Two or more Fast
Ethernet connections are combined in order to increase the bandwidth and to create a resilient
and redundant link
.
Seamless Ring Port Restoration
Seamless restoration is a new patented technology which can restore a failed ring without
causing any loop problem, topology change and packet loss. With a 0 second restoration time,
this mechanism eliminates any unstable status and guarantees the applications running non-
stop.
Rapid Dual Homing (RDH) Technology
Rapid Dual Homing is also the important feature of new generation Ring technology. It supports
ring coupling with other vendors and with easy configuration and multiple redundancies, the
failover time is much faster and the restoration time is zero ms. Uplinks can be auto detected
and gathered into groups. In each group, uplinks are sorted into primary, secondary and
