Abstract
A method for establishing a tunnel between VTEPs includes receiving at an SDN controller a tunnel creation request to establish a VxLAN tunnel from a first VTEP to a second VTEP, determining a VxLAN tunnel of network nodes coupling the first VTEP to the second VTEP, assigning a SvcPI to the VxLAN tunnel, and sending a tunnel initiation command to the first VTEP, the tunnel initiation command causing the first VTEP to convert an Ethernet frame to a path-ID frame by adding an NSH encapsulation header and to forward the path-ID frame to the next network node in the VxLAN tunnel.
