Abstract: Embodiments of this application disclose a data processing method for avoiding a packet loss and for improving user experience. The method in the embodiments includes: sending, by a cable modem termination system CMTS, a dynamic bonding change (DBC) request to a cable modem (CM), where the DBC request is used to request the CM to change a modulation profile group corresponding to the downstream channel from a first profile group to a second profile group. The first profile group is a profile group currently supported by the CM, and at least one target profile in the second profile group is not in the first profile group. The method further includes sending, by the CMTS, a first downstream data packet to the CM by using any profile in the first profile group, and sending a second downstream data packet to the CM by using the target profile.

Abstract: The present invention provides a method, a device, and a system for authentication, which can avoid the problem of password disclosure caused by that authentication password information is manually input or authentication password information is not changed within a long time period and improve authentication password information security. The method includes: generating, by a network information management system, first password information and delivering a first notification message carrying the first password information to an optical line terminal, so that the first notification message delivered by the network information management system is transparently sent to an optical network unit through the optical line terminal; and implementing, by the optical network unit, authentication with the optical line terminal according to the first password information in the first notification message.

Abstract: The present invention provides a data communication method, where the method includes: receiving, through a first port of a first optical network unit, a first message sent by a first optical line terminal, where the first message is used to instruct the first optical network unit to switch to the second port from the first port; and after the first optical network unit switches to the second port from the first port according to the first message, performing data communication with a second optical line terminal through the second port. It is ensured that switchover time between the OLTs is within 50 ms, and reliability of data communication is further improved.
