As mentioned above, there are a kind of needs to method and apparatus, suppose under the restriction of certain cable modem standard and available hardware and software element, can allow cable modem manufacturer, just cable modem operator is that all cable modem hardware platform uses a configuration file, and provides unique operating software for the cable modem of different trade marks and model simultaneously.Especially, DOCSIS standard (cable data service interface specification) has illustrated a kind of mechanism, by this mechanism, configuration information and operating software version information is offered cable modem, for example the cable modem 20 of Fig. 1.Therefore, the present invention can move under the restriction of those standards.
The process of configuration cable modem is shown in the process flow diagram of Fig. 3, and this process must be carried out when powering on the cycle at every turn.When cable modem 20 powered on, the processing procedure of Fig. 3 started from step 70.So cable modem 20 is related with Cable Modem Terminal System 52 in step 72, distribute (seeing step 74) with receive channel, be used on the uplink and downlink direction, sending data by wired system 10.In step 76, cable modem 20 to Dynamic Host Configuration Protocol server issue to IP address and the request that comprises the profile name of cable modem configuration parameter.The IP Address requests is broadcast to all available Dynamic Host Configuration Protocol server.Cable modem 20 is selected IP address and profile name simply from first Dynamic Host Configuration Protocol server, with the response broadcast request.To during interactive sessions, use the IP address, to allow cable modem 20 to arrive and to communicate by letter with the website on internet or other external networks.The IP address is given during one section configuration of cable modem by " taxi ".In the time of during surpassing " taxi ", cable modem is from IP address that the Dynamic Host Configuration Protocol server request was upgraded.Usually, update request is licensed.In step 78, Dynamic Host Configuration Protocol server sends title and address (being tftp server address) of configuration file to cable modem 20.
In the prior art, each Dynamic Host Configuration Protocol server comprises identical configuration filename.Therefore, respond its request, each cable modem in the wired system 10 receives this identical configuration filename.In the prior art, according to the DOCSIS standard, configuration file refers to single operating software name.Therefore, the operation of each cable modem is controlled by identical operating software.The instruction according to the present invention, the content of configuration file are used to its unique operating software file of cable modem indication, and this is based on cable modem trade mark and model, or the cable modem group indication that is distributed symbol.
In step 80, cable modem 20 is provided by the title that provides at step 78 place, uploads configuration file from the TFFP server.As is known to the person skilled in the art, TFTP sends data with 5 12 continuous block of bytes.Block of bytes is processed at receiving end, until receiving the block of bytes that has comprised the block of bytes that is less than 512 bytes or comprised zero bytes.In the both of these case any one shows that the TFTP session finishes.
Known to those skilled in the art, except the cable modem operating software filename of theme of the present invention, configuration file also comprises many configuration settings, and it has comprised that the general standard configuration of whole wired system and manufacturer formulate is used for particular cable modem hardware platform.The content of configuration file is the form of scale-of-two (.bin) type.Type field has been the definition listed in the value field single byte-identifier symbol of configuration parameter.Length field also is an one-byte field, and it determines the length of value field following closely.The value field scope is 1 to 254 byte, and comprises the employed particular value of configuration parameter.

In step 82, configuration file is verified.If configuration file is effectively, just read the operating software field of configuration file in step 84.In the prior art, this field comprises the filename of relevant cable modem.Its disadvantage is, this single filename and relative single operating software can not adapt to the various cable modems that use on the wired system, comprise from different manufacturer and from the cable modem of the different model of a manufacturer.For example, when cable modem manufacturer has issued the new cable modem model that has the CPU (central processing unit) different with previous model, just must be with the bells and whistles of software upgrading with the use new processor.If all modulator-demodular units are restricted to and use minimum common features operating software operation on the wired system, just can not obtain to incorporate into some characteristic and function in the hardware element.Therefore, to be used for the unique of each cable modem and optimum operation software obviously be favourable in identification.
In step 86, software matrix filename that downloaded, that be stored in the cable modem 20 is now compared during the operating software listing file name that will read at step 84 place and the power up formerly.If version number does not match, then process moves to step 88, here from the nearest version of TFTP file server downloading-running software matrix file.At step 78 place, will call that TFTP file server address from Dynamic Host Configuration Protocol server and offer cable modem 20.
Note, changed the operating software file of reference in the tabulation whenever, also must change filename because operating software listing file name comprises version information.For example because, the main software version has added new characteristic, less important version is repaired software vulnerability, or wherein has only several line codes to pass through the patch release of revising, and may carry out this operating software and change.Should further note, before step 88 place downloads redaction, cable modem 20 at first storage running software matrix file than older version.When downloading process went out to have damaged file or makes file not readable owing to any reason, cable modem 20 can continue to use old FileVersion, is successfully downloaded until redaction.
If the existing version file that is stored in cable modem 20 is actually the recent release of file, or in case downloaded nearest version in step 88, process proceeds to step 90, uses modulator-demodular unit classification or other hardware identifiers to make symbol herein and consults the version list file for the index that enters tabulation.
Exemplary operating software listing file is as shown in the table:
