Pro-Ring II is a new Ring mechanism for Lantech Industrial Switches in which it eliminates the need to pre-set the Master switch in old Pro-Ring and yet to protect the network by much secure topologies than ever. Pro-Ring II works as a Ring Chain to reduce the risk of master switch linking down whereas the setup becomes much easier. Pro-Ring II can be backward compatible with old Pro-Ring by down-grading the Ring scheme to old one.
Nowadays Pro Ring II is more advance than old Pro Ring I system in applications, which including Daisy-Couple Ring, Multi-Couple ring, Advanced Dual Ring, *Key Ring and *Multi-Key Ring.
Daisy-Couple Ring
For larger and single LAN group, Daisy-Couple Ring could achieve self-recovery time in less than 10ms in which the ring group will choose automatically for Master switch, detect loop and form path recovery architecture.
Multi-Couple Ring
For multiple ring groups, it helps to structure ring activities among different LANs. Each ring group has more than 3 redundant paths for backup.
Advanced Dual Homing
When the ring group is connected to upper switch by RSTP algorithm, it strengths the uplink connection with its own redundant path which double secures the link than of traditional Dual Homing.
Key Ring
When the middle or aggregation points are critical, Key Ring can protect the middle connection to the core or upper switch by separating different layers of links or ring groups.
Multi-Key Ring
Multi-Key Ring forms triangle connection among different ring groups to create the de-militarized zone in the network topology and maintain the redundancy.
