Multiple Super Ring (MSR)
The most common industrial network redundancy is to form a ring or loop. Typically, the
managed switches are connected in series and the last switch is connected back to the first
one. In such connection, you can implement the Multiple Super Ring technology to get
fastest recovery performance.
Multiple Super Ring (MSR)
technology is 3
rd
generation Ring redundancy technology. This
is patented and used in countries all over the world. MSR ranks the fastest restore and
failover time in the world, 0 ms for restore and about milliseconds level for failover for
100Base-TX copper port. The other interface may take longer time due to the media
characteristics.
Advanced
Rapid Dual Homing (RDH)
technology also facilitates
Managed Switch
to
connect with a core managed switch easily and conveniently. With RDH technology, you
can also couple several Rapid Super Rings or RSTP cloud together, which is also known
as Auto Ring Coupling.
TrunkRing
technology allows integrate MSR with LACP/Port Trunking. The LACP/Trunk
aggregated ports is a virtual interface and it can work as the Ring port of the MSR.
MultiRing
is an outstanding technology. The Multiple rings can be aggregated within one
switch by using different Ring ID. The maximum Ring number one switch can support is
half of total port volume. For example, if the Managed Switch is a 24 Fast Et 4
Gigabit port design, that means maximum 14 Rings (12 x 100M Rings and 2 Gigabit Rings)
can be aggregated to one 24+4G Managed Switch. The feature saves much effort when
constructing complex network architecture.
New Ring:
To create a Rapid Super Ring. Just fill in the Ring ID which has range from 0 to
31. If the name field is left blank, the name of this ring will automatically naming with Ring
ID.
