RapidRing® is a new technology from CTRLink that provides redundancy for Ethernet networks. The CTRlink series of managed switches provides two types of redundancy options.


RapidRing® redundancy:
Allows switched networks to be wired in a ring utilizing fiber or copper.
Any break in the ring will be recovered in less than 300 ms (with up to 50 switches).
Relay contacts, flashing LEDs and SNMP traps help to quickly identify broken links.
Supports dual ring structures.

See the tutorial and white paper for more information.



Trunking redundancy:
Any break in the trunk will be recovered in less than 10 ms.
Relay contacts, flashing LEDs and SNMP traps help to quickly identify the broken links.
Trunking also provides more bandwidth between switches

See the tutorial and white paper for more information.



RapidRing® and Trunking redundancy are available on the EISX8M, EICP8M and on the
EISB8M, EISB16M or EISB24M family of products.
