Abstract
In order to provide a redundancy mechanism in a packet switched provider network, which allows faster recovery from a failure, it is proposed that in case of a failure, a redundancy mechanism is initiated to reroute packet transmission through the provider network via an alternate path and an address withdrawal message is sent to network nodes along the failed path using data plane protocol. A network node receiving the address withdrawal message will flush MAC addresses it had learned before.
