RDH Peer protection
TrunkRing
TM
Integrate port aggregate function in ring path to get higher throughput ring
architecture
MultiRing
TM
Couple or multiple up to 10 Rapid Super Rings in one device, JetNet 5020G supports up
to 8 100M rings and 2 Gigabit rings
Super Chain
It is new ring technology with flexible and scalability, compatibility, and easy
configurable. The ring includes 2 types of node Switch – Border Switch and Member
Switch
Rapid Spanning Tree
IEEE 802.1D-2004 Rapid Spanning Tree Protocol. Compatible with Legacy Spanning Tree
and IEEE 802.1w
Multiple Spanning Tree
IEEE 802.1s Multiple Spanning Tree, each MSTP instance can include one or more
VLANs, and also supports multiple RSTP deployed in a VLAN or multiple VLANs
ITU-T G.8032 ERPS
Support ITU-T G.8032 ERPS V1 single ring topology, and ERPS v2 multiple rings with
ladder topology
Loop Protection
The Loop Protection prevents any network looping caused by RSTP and MSR ring
topology change
