Claim:
1. A method of optical label swapping implemented by a switch used in a software defined network system comprising: providing a payload signal having a Nyquist shaped carrier in a first bandwidth spacing using a payload generator module controlling at least one first optical laser; inserting an optical label adjacent to the payload signal in a second bandwidth spacing with a label generator controlling at least one second optical laser, the optical label either preceding or following the payload signal, wherein the label generator and the payload generator are controlled by said software defined network (SDN) system including at least one hardware processor; transmitting a package of the payload and the optical label to a receiving node; and swapping the optical label at the receiving node with a flex grid wavelength selective switch (WSS) controlled by the software defined network; wherein the payload signal is at 400-Gbit/s, the first bandwidth spacing is 75-Ghz, the second bandwidth spacing is remainder of a 100-Ghz bandwidth spacing that encompasses the first bandwidth spacing, and the optical label is at a 10 GbE data rate.
