Seamless Ring Port Restoration TM Seamless restoration is a new Korenix patented technology which can restore a failed ring without causing any loop problem, topology change and packet loss. With zero second restoration time, this mechanism eliminates any unstable status and guarantees the applications running non-stop. Rapid Dual Homing (RDH TM ) Technology Rapid Dual Homing is also an important feature of Korenix new generation Ring technology. It supports ring coupling with other vendors devices. Moreover, providing easy configuration and multiple redundancies, the failover time is much faster and the restoration time is zero ms. Uplinks can be auto detected and gathered into groups. In each group uplinks are sorted into primary, secondary and standbys based on their link speed. The uplink with the highest speed is more likely to be active path for data transmission. Link aggregation is also integrated into RDH TM . An uplink connection can be a single link or several links aggregated as a trunk, which provides better redundancy and link capacity. 1-to1 connection n-to1 connection 1-to-n connection n-to-n connection trunk connection Rapid Dual Homing Ethernet Ethernet JetNet 4508f V2 Ring Coupling Ethernet Ethernet JetNet 4508f V2 259 www.korenix.com A Beijer Electronics Group Company
Industrial L2 / L3 Rackmount / Rail Ethernet Switch TrunkRing TM TrunkRing is a new feature in MSR which merges the two technologies of RSR and link aggregation. It takes advantages of aggregation to enhance the link redundancy, while increasing the link speed. The ring will open only if all the aggregated links are broken. Link aggregation can be achieved by either static trunk or LACP. Not all the link sections in a TrunkRing need to be the same. Ring links can be either symmetric or asymmetric. Some are a single path, and the others are aggregated by links where the number of links in a trunk group can be different. Users can enhance the link redundancy at different locations in accordance to the need. The link with less speed is more likely to be used as the backup path for restoring the network to full play capacity.

The simplest example is to connect two rings by a single device. Depending on the number of ports and the speed, the JetNet 4508f V2 can connect as a 100Mbps ring and uplink with JetNet 5010G or higher level Korenix Industrial Switch. As shown in the below figure, MultiRing TM technology simply extends the network topology by linking multiple rings into a line or into multiple directions. In addition to extensibility, MultiRingTM has great diversity of various ring technologies. When MultiRing TM enabled, JetNet 4508f V2 can connect RSR rings, TrunkRing TM and a Super Ring together and simultaneously provide more Fast Ethernet Ring connectivities. This provides extensibility to new technologies while keeping the great backward compatibility.
