| 摘要 |
The present invention relates to a network management method in an optical network for performing automatic neighbor discovery. A device (10) is connected over an Ethernet connection (12) to an Optical Transport Network, OTN, device (11), which transparently maps Ethernet packets to Optical Data Units and vice versa. The method comprises the steps of: determining (21), by a first of the devices (10, 11), that a port (14) of the OTN device (11) is connected via the Ethernet connection (12) to a port (13) of the device (10); and sending (23), by the first device, a link configuration pattern over the Ethernet connection (12), the link configuration pattern being one of: a bit sequence, an invalid Ethernet packet and a valid Ethernet packet, the link configuration pattern containing an ID identifying the first device and a port number identifying the port of the first device. |
