Overture Awarded Patent for Protected Switching Ring Technology

Overture Networks was awarded a U.S. patent for "Protected Switching Ring" (PSR) technology that provides sub-50 millisecond failover for Gigabit Ethernet rings. Overture Networks' PSR algorithm provides for a ring topology that can be built using standard Ethernet technology and methodology.


Overture said Protected Switching Rings can be implemented as a software upgrade to its ISG platform. PSR capabilities on the ISG interwork seamlessly with existing Layer 2 switches and backbone DWDM, Resilient Packet Ring (RPR) or SONET/SDH transport systems to provide a capability that operates much like traditional UPSR configurations.
