摘要： A method for signalling of data transmission path properties is proposed. The method contains several steps at a first network endpoint device. As a first step, at least one data transmission path is provided via a client-server interface to a client device by the first network endpoint device. The data transmission path is a path through the network connecting the first network endpoint device and a second network endpoint device. As a second step, the first network endpoint device receives via a server-network interface OAM information generated by the second network endpoint device or internal network devices and terminates this received OAM information. As a third step, the first network endpoint device determines at least one data transmission property parameter from such received OAM information which was generated by the second network endpoint device or internal network devices. The fourth step is that of signalling via the client-server interface at least one transmission property message towards the client device in dependence on the at least one determined transmission property parameter.

The OAM loopback function allows any RPR station to check the reachability of another RPR station. It is not necessary to stop any data traffic communication on the network in order to perform this function.

摘要： 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.
