Abstract
Methods and systems for encryption control in optical networks without data loss enable various transitions related to encryption of an ODU data payload. A transition from unencrypted data payload to encrypted data payload is performed without data loss or dropping of OTN frames. A transition from encrypted data payload to unencrypted data payload is performed without data loss or dropping of OTN frames. A rotation of the encryption key to another encryption key is also performed without data loss or dropping of OTN frames.
