Abstract

This paper introduces a new web based method to remotely upgrade firmwares of Cable Modems (CM) which are integral part in providing high-speed Internet access through Hybrid Fiber Coaxial (HFC) networks. Also, it discusses various practical problems arising in the upgrading process. Traditional upgrade has been performed by modifying the CM configuration fie. This paper shows a new web based CM firmware upgrade method using SNMP and MIB which greatly reduces upgrading time, cost and man-hour than traditional firmware upgrade methods. This method has been shown to be very efficient and practical. This method will make significant impact especially because tens of million cable modems are currently waiting to be upgraded soon to the next version from the current version.
