Abstract
Methods for automatically discovering links between a first node of a first operating domain and a second node of a second operating domain of a communication network are disclosed. The methods may be implemented at the first node, the second node, or a control node. The first and second nodes communicate in-band control messages. These messages are encoded using a size of the packets of the control messages, and provide information about the first node and a first interface used by the first node for sending the control messages. The first and second nodes also communicate link messages with the control node. The link messages comprise information received in the in-band control messages and information about a second interface used by the second node for receiving the in-band control messages.
