Abstract: The present disclosure provides a method for the master to configure the slaves for use in a passive optical network (PON) system, comprising: the slaves generating a managed entity (ME) Support List ME based on their individual hardware configuration; the master obtaining the ME Support List ME; and the master configuring the slaves based on this list. The technical solution of the present disclosure allows speeding up of the optical network terminal (ONT) service clearance time by quickly identifying incompatibility of the optical line terminal (OLT) with the ONTs.

Abstract: A method for mapping a service flow to a service transmission channel includes: configuring determined configuration parameters for a message characteristic into an Optical Network Terminal (ONT); the ONT ensures that the received service flow matches the configured message characteristic; mapping the service flow to a specified service transmission channel. A system and an ONT for mapping the service flow to the service transmission channel are also provided, and the system sets a general service flow mapping module in the ONT. Service flows may be mapped to different service transmission channels based on any predetermined message characteristic by the method, system, and ONT of this invention and it meets the demand of the subdivision service QoS.

Abstract: The present invention discloses a method for controlling multicast flow in passive optical network includes: receiving multicast data from the optical line terminal, determining whether the received multicast data satisfies a multicast right control condition, transmitting the multicast data to the user side if the received multicast data satisfies the multicast right control condition, or discarding the multicast data if the received multicast data does not satisfy the multicast right control condition. The present invention also discloses an optical network terminal, an optical line terminal, and a system consisting of an optical network terminal and an optical line terminal and an optical distribute network, which implement the above mentioned method. The present invention could prevent the optical network terminal from receiving illegal multicast data and enhance the multicast security of the whole passive optical network system.

Abstract: The present invention discloses a message processing method of optical network termination (ONT), including: the ONT receiving an uplink message; the ONT performing a corresponding VLAN tagging operation in accordance with the characteristic value of the uplink message, wherein at least two types of uplink messages with different characteristic values have different VLAN Tags after the uplink messages are processed by the ONT. The present invention also discloses a VLAN Tag processing apparatus, an optical network termination (ONT), and a passive optical network system, which enable subsequent network devices to process the messages from the ONT in diverse ways.

Abstract: In a method for ensuring data security in a PON, when an Optical Line Terminal (OLT) configures an encryption attribute of a channel of an Optical Network Unit (ONU)/Optical Network Termination (ONT), the OLT and the ONU/ONT process plaintext data on the channel of the ONU/ONT before a key switching time and process ciphertext data using a new key on the channel at the key switching time simultaneously; when the OLT cancels the encryption attribute of a channel of the ONU/ONT, the OLT and the ONU/ONT process ciphertext data on the channel before the key switching time and process plaintext data on the channel simultaneously at the key switching time. Through the method, synchronization of encryption and decryption between the OLT and the ONU/ONT when the OLT configures or cancels the encryption attribute of a channel of the ONU/ONT is implemented.
