Abstract

The invention relates to a cable modem, which comprises a communication module, a verification module, a judgment module and an execution module, wherein the communication module is used for establishing communication connection with a server and receiving a code file, the verification module is used for carrying out signature verification according to manufacturer verification information in the code file, the judgment module is used for judging whether signature verification is successful or not, the execution module is used for executing the code file when signature verification is successful so as to acquire firmware download information, and the communication module is further used for receiving corresponding firmware from the server according to the firmware download information so as to complete an upgrading operation. According to the cable modem, the server and the firmware upgrading method provided by the invention, verification of the code file can be passed quickly, appropriate upgrading firmware can also be matched quickly, and occurrence of a circumstance of mismatching in upgrading is prevented.

Description

technical field [0001] The invention relates to the field of data transmission, in particular to a cable modem, a server and a method for upgrading firmware. Background technique [0002] The communication of the cable modem is the same as that of the common modem, it is the process of interactive transmission of data signals on the analog channel, but there are also differences. The transmission medium of the common modem is independent between the user and the access server. That is, the user exclusively owns the transmission medium, while the transmission medium of the cable modem is a hybrid fiber-coaxial cable network (HFC for short), which modulates the data signal to a certain transmission bandwidth and shares the medium with the cable TV signal; in addition, the cable modem There is no need to dial up the Internet, do not occupy the telephone line, and can provide all-weather service of online connection at any time. [0003] The existing cable modem products have t...
