Pro Ring System - What is it ?

For Ethernet, network redundancy means a network hardware link down or disconnection cable will not interrupt communications. Also, to achieve network redundancy, one must use a managed switch, since advanced traffic management is required to prevent "looping" of data packets. Where an interruption of a few seconds is acceptable in the office, it’s an eternity for most manufacturing environments or other mission-critical networks. A communication gap of a few seconds or more could cause loss of critical data or worse yet -- system shutdown. Common enterprise technologies like Rapid Spanning Tree Protocol (RSTP) generally take between 2 to 10 seconds to recover after a fault, and older technologies like Spanning Tree Protocol (STP) could take even longer -- 30 to 60 seconds.
