Fault Tolerant, Plug-n-Play – Hiper Ring
 
One of major advantage of Hirschmann Devices, is that we get Media Redundancy by forming a Hyper Ring. Both Copper and fiber can be used to for a ring (as supported by the devices selected). In the ring, one of the devices is set as the Redundancy Manager. This manager maintains one segment of the ring as a standby path (the dotted line in the fig). The manager continuously monitors the status of the ring. If it detects a fault in the network (which can occur because of either a link between any two devices failing, or the device itself failing), it will connect the standby path immediately. The reconfiguration time is 20mSec for shared Ethernet with 50 Hub in the ring and a maximum of 500 mSec for switched Ethernet, with 50 switches in the ring.
 
 
Hiper ring can be formed between various managed switches of Hirschmann and can have different media between various switches (copper, Multimode & Singlemode fiber) etc. Also the maximum distance between switches varies for different media (Example: Copper - 100M, Multimode fiber – 5KM, Singlemode fiber – 30KM, Long Haul Singlemode fiber – 100KM).
 
Hiper Ring Vs Spanning Tree Protocol
 
Sr.No. Hiper Ring Spanning Tree Protocol
1 This method takes very less time for reconfiguration. Reconfiguration time is less than 500 msec This method takes very long time for reconfiguration. Reconfiguration time is 30 sec

2

This method supports up to 50 switches in ring

This method supports less than 7 switches. Spanning Tree Domains must not include more than 7 switches

3

Simple Network Design (Only dip switch setting)

Complex Network Design (Requires an expert to do so).

4

Maximum Distance: More than 5000 KM with 50 Switches in Hiper Ring

Maximum Distance: Less than 7 KM
