Abstract
A method performed under a transport SDN (Software Defined Network) controller may include classifying respective ones of a plurality of target nodes as either first target nodes that belong to a first domain or second target nodes that belong to a second domain, selecting a first core node in the first domain and a second core node in the second domain, calculating a first pseudo-wire (PW) between the selected first core node and the classified first target nodes, and calculating a second pseudo-wire (PW) between the selected second core node and the classified second target nodes.

A method performed under a transport SDN (Software Defined Network) controller, comprising:
- classifying respective ones of a plurality of target nodes as either first target nodes that belong to a first domain or second target nodes that belong to a second domain;
- selecting a first core node in the first domain and a second core node in the second domain;
- calculating a first pseudo-wire (PW) between the selected first core node and the classified first target nodes;
- and
- calculating a second pseudo-wire (PW) between the selected second core node and the classified second target nodes.
A method performed under a transport SDN controller, comprising:
- classifying a plurality of target nodes that belong to a corresponding domain;
- selecting a core node, in the corresponding domain, to be connected with the classified target nodes;
- and
- calculating a pseudo-wire (PW) between the core node and classified target nodes in reference to the core node.
A transport SDN controller comprising:
- a path request processor configured to receive a multi-node path request from a client;
- a database configured to store network information related to network devices included in a first domain and a second domain;
- and
- a path calculator configured to retrieve the network information from the database, and classify, based on the network information, a plurality of target nodes into first target nodes that belong to the first domain and second target nodes that belong to the second domain, select a first core node in the first domain and a second core node in the second domain, calculate a first pseudo-wire (PW) between the first core node and the first target nodes in reference to the first core node, and calculate a second pseudo-wire (PW) between the second core node and the second target nodes in reference to the second core node.
