Abstract

In one embodiment, a method for telecommunications includes steps of receiving a first packet through a first port, and determining whether the first packet arrived over a protected path. If the first packet arrived over a protected path, the method also includes the steps of hashing a source address of the first packet, adding a first entry into a forwarding table, and adding a second entry into the forwarding table. The protected path is coupled to at least the first port and a second port. The first entry includes the result of hashing the packet, and an identification of the first port. The second entry includes the result of hashing the packet, and an identification of the second port.
