S-Ring

GarrettCom’s S-Ring product enables 6K Managed Switches to simplify and speed up recovery from faults in Ethernet LAN configurations that use a ring structure.The benefit of using S-Ring over RSTP-2004 is that it will only require one managed switch within a ring, significantly reducing hardware costs .

S-Ring It is built upon networking software standards such as IEEE 802.1d Spanning Tree Protocol (STP). The user configures and controls S-Ring as part of the 6K Switch’s management software. The S-Ring product can be used in multi-vendor LANs running standard STP on the 6K's along with other switches and hubs in any redundant LAN topology, including rings and meshes. S-Ring makes Ethernet ring-topology more reliable and faster without sacrificing the benefit of standards-based interoperability.
