Independent Ring Operation<br />
Unlike traditional redundancy technologies, such<br />
as RSTP, which takes all LAN devices as a single<br />
system, each of Korenix redundant rings operates<br />
independently. The influence of any network failure<br />
is limited within the ring itself and will not spread to the<br />
other parts, as a result ensuring network scalability and<br />
high quality data transmission.<br />

IEEE 802.1s Multiple Spanning Tree Protocol<br />
The <strong>JetNet</strong> series support IEEE 802.1s Multiple Example: Instance 1 represents VLAN 20. Instance 2<br />
Spanning Tree Protocol (MSTP). The switch with represents VLAN 10.<br />
enabled MSTP can select the root switch for each In instance 1, there is one root and one blocking path.<br />
instance, and block and form the forwarding path for The VLAN 20 data can be transmitted from switch 3 to 1,<br />
each instance. Each instance represents one VLAN. It is and then to 2 or vise versa.<br />
the limitation in STP/RSTP as the 2 traditional protocols In instance 2, there is another root and another blocking<br />
can only block one path for all the existing VLANs in the path. The VLAN 10 data can be transmitted from switch<br />
same environment.<br />
3 to 2, then to 1 or vise versa.<br />
