Abstract
A telecommunications system including a plurality of switches defining an Ethernet ring; a plurality of virtual local area networks defined on the Ethernet ring, defining a number of virtual local area networks (VLANs) equal in number to the number of links; and a ring recovery system configured to recover from a link failure by rerouting traffic to a destination on the Ethernet ring via a VLAN not including a failed link.
