4.2 Multiple Ring
4.2.1 Introduction
Multiple Ring is the revolutionary network redundancy technology which enhances network
redundancy for any backbone networks, providing ease-of-use and maximum fault-recovery
swiftness, flexibility, compatibility, and cost-effectiveness in a set of network redundancy
topologies. The self-healing Ethernet technology designed for distributed and complex industrial
networks enables the network to recover in less than 30 milliseconds (in full-duplex Gigabit
operation) or 10 milliseconds (in full-duplex Fast Ethernet operation) for up to 250 switches if at
any time a segment of the chain fails.
Multiple Ring allows multiple redundant rings of different redundancy protocols to join and function
together as a large robust network topology. It can create multiple redundant networks beyond the
limitations of current redundant ring technologies.
