Problems solved by technology

In the current application of EOC on the live network, the EOC chip is upgraded by direct firmware or PIB provided by the chip manufacturer. It is necessary to upgrade the firmware and then upgrade the PIB. Each upgrade will be repeated twice, and the steps are cumbersome.
When the number of devices to be upgraded is relatively small, the workload is acceptable, but when it is necessary to upgrade the entire network, the workload is obviously doubled

Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] see figure 2 As shown, the embodiment of the present invention provides a method for upgrading EOC software using a combined file, including the following steps:

[0032] Download the firmware upgrade file and PIB upgrade file, and make the merged file required for the upgrade: After packing the firmware upgrade file and the PIB upgrade file into a merged file, add the following 5 fields to the file header of the merged file: chip solution field , checksum information field, firmware version information field, firmware file size field and PIB file size field;

[0033] Place the merged file on the upgrade server; download the merged file to the device; analyze the merged file downloaded to the device, verify the correctness, integrity, and version of the upgrade file, and upgrade the device only if the verification is complete...

Abstract

The invention discloses a method and a system for updating EOC software by adopting combined files, relating to the field of access of integration of three networks. The method comprises the following steps: downloading a firmware updating file and a PIB updating file, packaging the firmware updating file and the PIB updating file into a combined file, and adding five fields, namely chip solution, checking and information, firmware version information, firmware file size and PIB file size, into the file header of the combined file; putting the combined file on an upgrading server; and downloading the combined file to equipment; analyzing the combined file downloaded to the equipment, checking the accuracy, completeness and version consistence of the upgraded file, updating the equipment only when the checking is complete, and returning the upgrading result. According to the method, the upgrading operations are reduced, the firmware is matched with PIB, the workload is reduced, meanwhile, the upgrading safety is improved, and the abnormal work caused by mismatching of the firmware and the PIB after updating can be avoided.

Description

technical field [0001] The invention relates to the technical field of EOC (Ethernet Over Cable, Ethernet data is transmitted through a coaxial cable) access technology field of triple network integration, in particular to a method and a system for upgrading EOC software by merging files. Background technique [0002] Firmware (Firmware) is a program written in EROM (Eraseable ReadOnly Memory, erasable read-only memory) or EEPROM (Electrically-Erasable Programmable Read-Only Memory, electrically erasable programmable read-only memory). In the EOC (Ethernet Over Cable, Ethernet data is transmitted through the coaxial cable) system, the EOC firmware is the system software run by the CPU in the head end or EOC terminal. PIB (ParameterInformationBlock, parameter information block) is the configuration file required by the EOC head end or EOC terminal CPU software to run, and it is some necessary configurations required by the EOC chip. [0003] In the EOC access system, the EOC...
