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 system 100 for storing encrypted data. The system 100 comprises a server 101 and a plurality of clients 102. A first client 102a of the plurality of clients 102 is configured to send to the server 101 a first reference value 103 calculated from data to be encrypted and stored. The server 101 is configured to determine a group 104 of second clients 102b from the plurality of clients 102, the second clients 102b having each sent to the server 101 data with a second reference value equal to the first reference value 103. The group 104 of second clients 102b is configured to perform a passive key exchange protocol 105 with the first client 102a, and the server 101 is configured to determine, based on a result of the passive key exchange protocol 105, whether the data is to be stored in full or as deduplicated data.
