The invention provides an ONU (Optical Network Unit)-transferable TWDM-PON (Time and Wavelength Division Multiplexed Passive Optical Network) system which can realize flexible transfer of online users on different active wavelengths via a specific protocol, and specifically realizes information interaction of an ONU and an OLT (Optical Line Terminal) in the migration process under the existing EPON (Ethernet Passive Optical Network) protocol through redefining some MAC (Media Access Control) protocol frames. The ONU-transferable TWDM-PON system adopts the technical scheme comprising the steps as follows: a, the ONU is registered in the system via the IEEE802.3ah multi-point control protocol, and a unique logical link identifier and a wavelength identifier are distributed for the new registered ONU; and b, the OLT requires the ONU to perform transfer via the specific protocol, and then the ONU exits the registration and performs re-registration according to the requirements of the OLT. According to the invention, under the situation of not influencing service quality for users, flexible transfer of online users on different active wavelengths can be realized via the specific protocol.

The invention discloses an anti-countermeasure attack camera source recognition method based on local smooth projection. The method comprises the following steps: 1) preprocessing a camera image; 2) constructing a camera source recognition feature extraction network; 3) generating a noise image block set; 4) defining a local smooth projection loss function; 5) constructing a camera source recognition front defense network; 6) an application recognition model.

The SDN controller cluster system comprises an SDN controller cluster and a database server cluster, wherein each SDN controller in the SDN controller cluster comprises a local cache and a Zookeeper database, and the SDN controller cluster comprises a main SDN controller and a plurality of standby SDN controllers; the database server clustercomprises a plurality of local DBs; the local cache of the main SDN controller is in data communication with the local DB of the database server cluster; and the Zookeeper database of the main SDN controller is in data communication with the Zookeeper databases of other standby SDN controllers to realize data synchronization. According to the SDN controller cluster system, the database server cluster is adopted to replace local databases of all SDN controllers, and the SDK controllers do not need to operate the databases, and the pressure of SDN control processing data is relieved; and afterthe master-slave switching, the synchronous data source is changed, so that the data consistency is ensured, and the service interruption caused by the data difference is avoided.

The invention relates to a coating interface treating agent and a preparation method thereof. The preparation method comprises the following steps of: adding a titanate coupling agent NDZ-401 and LTH adhesive force promoting resin into a main solvent formed by butanone, n-butyl alcohol and cyclohexanone and adding BYK401 for sufficiently mixing. When the coating interface treating agent is sprayed onto the surface of a cured coating, the coating can be slightly swelled; after permeated into the surface of the slightly swelled coating, the coating interface treating agent interacts with the components of the cured coating so that an adhesive force between the coating interface treating agent and the newly coated coating on the upper layer is equal to the force of artificial hacking, and therefore, the artificial hacking technology with lower efficiency and difficulty in construction at present can be replaced.
