Abstract: A method performed by an optical node, operating as a first network edge device of an optical layer one virtual private network (L1VPN), includes generating, by a first module of the optical node, a first optical data frame, where the first optical data frame includes an L1VPN overhead, and where the L1VPN overhead includes a control plane communication field; generating, by a second module of the optical node, a first control plane message for a second network edge device of the optical L1VPN, where the second network edge device is connected to the first network edge device across a provider network via an optical L1VPN link; incorporating, by the first module, the first control plane message into the control plane communication field of the first optical data frame; and transmitting, by the first module, the first optical data frame to the second network edge device via the optical L1VPN link.

Abstract: A node is configured to receive first optical channel data unit (ODU) signals; encapsulate the first ODU signals into a second ODU signal; distribute data of the second ODU signal to a group of third ODU signals; encapsulate each of the third ODU signals into a respective optical channel transport unit (OTU) signal; and transmit each of the OTU signals on a respective optical channel of a group of optical channels. Each optical channel, of the group of optical channels, has a corresponding one of group of wavelengths. The data of the second ODU signal is carried by the group of optical channels.
