Rapid Dual Homing (RDH
TM
) Technology
Rapid Dual Homing is also the important feature of Korenix 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 restore time is zero ms. Uplinks can be auto detected and gathered into
groups. In each group, uplinks are sorted into primary, secondary and
standbys by their link speed. The uplink with the highest speed is more likely to
be active path for data transmission. Link aggregation is also integrated into
RDH
TM
. An uplink connection can be a single link or several links aggregated
as a trunk, which provides better redundancy and link capacity.
TrunkRing
TM
TrunkRing is a new feature in MSR which merges the two technologies of RSR
and link aggregation. It takes advantages of aggregation to enhance the link
redundancy, while increase the link speed. The ring will open only if all the
aggregated links are broken. Link aggregation can be achieved by either,
static trunk or LACP. Not all the link sections in a TrunkRing need to be the
same. Ring links can be either symmetric or asymmetric. Some are a single
path, and the others are aggregated by links where the number of links in a
trunk group can be different. Users can enhance the link redundancy at
different locations in accordance to the need. And the link with less speed is
more likely to be used as the backup path for restoring the network to full play
capacity.
Link Aggregation Control Protocol
Link Aggregation Control Protocol allows
you grouping multiple Ethernet ports
in parallel to increase the link bandwidth. The aggregated ports can be viewed
as one physical port, so that the bandwidth is higher than just one single
Ethernet port. The member ports of the same trunk group can balance the
loading and backup with each other. The LACP feature is usually used when
you need higher bandwidth for the backbone network. This is a cost-effective
way for you to transfer much more data.

Some of Legacy PD devices also feature user defined manual mode and
forced powering mode to support non-standard PD devices without the PoE
signature resistor for some WiMax systems, which are non-compliant with
