Implementing an E-LAN between multi-nodes utilizing a transport network controller

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.
