Embodiment Construction

[0028] Such as figure 2 , image 3 As shown, this embodiment invents an automatic configuration method applied to cable bridge equipment by extending the existing dynamic host configuration protocol technology. The Dynamic Host Configuration Protocol is a protocol that can automatically assign an IP address to a client that logs into a TCP / IP network. This type of IP address is called a dynamic IP address.

[0029] Each cable bridge modem initially works on a default frequency band, and establishes a connection with the switch through this frequency band to obtain its own configuration data; Automatically configures the modem by sending it the configuration file that belongs to the modem.

[0030] In the entire remote automatic configuration system, the remote automatic configuration of the cable bridge switch itself is the first part that needs to be realized. It is the prerequisite for the successful automatic configuration of other devices; however, compared with other d...

Abstract

The method comprises: a) Cable Bridge Switch gets the management IP by using fixed allocation or dynamical DHCP allocation approach in order to establish IP layer communication; the central office server gets the remote automatic configuration information and the configuration files of all Modems, and configures its own work mode according to the configuration information; b) Cable Bridge Modem establishes connection with the Cable Bridge Switch via default channel to get its own configuration file; c) Cable Bridge Modem uses the obtained configuration file to set its own ECB' corrected Channel and working mode, and establishes link layer connection with the Cable Bridge Switch. Compared with currently-used technology, the invention can realize the automatic configuration of all network devices.

Description

technical field [0001] The invention relates to equipment based on cable bridge technology, in particular to an automatic configuration method for cable bridge equipment. Background technique [0002] The cable bridge is a new type of network device that provides network interconnection functions on coaxial cables. It uses a frequency above 860M, allowing users to establish a home network with a bandwidth of up to 270M on the existing cable TV cable at home. At the same time, users don't have to worry about destroying or interfering with the original cable TV signal. [0003] The cable bridge equipment will be configured to select a frequency band with a bandwidth of 50M above 860M for data transmission. Therefore, for the configuration of the cable bridge device, in addition to the configuration of the application layer such as the relevant IP address, it is also necessary to configure the frequency band of the physical layer. Existing network equipment needs to be confi...
