Abstract
A technique for protecting traffic in a Layer 2 (L2) communication network between a first and a second local nodes (CE, CE) interconnected via a redundant dual homed structure, the technique comprises a) distributing the traffic in the dual homed structure in a fault-free state, to form two traffic flows between the CEand CE; b) providing Layer 2 (L2) fault indications for the dual homed structure, in the form of operation and maintenance (OAM) tools, c) in a faulty state of the dual homed structure, forwarding traffic packets at the provider edges of the structure, based only on conventional physical fault indications and L2 fault indications, by locally making forwarding decisions for selecting an active communication line via the redundant dual homed structure.
