As a Senior Software Engineer, I was able to optimize Cable Modem Termination Systems (CMTS) operations, utilizing BSR 64000 platform designed to offer cable operators 99.9%+ system availability for subscriber IP voice, video, and data services. In doing so, I maintained ongoing collaboration with engineering, marketing, and technical support to present and discuss ideas to enhance product features, functionality, and reliability.My role allowed me to enhance Broadband Service Routers to support IPv6 CPE connection on a cable modem, facilitating layer 2-3 process and segregating control/data of IPv6 packets from the interfacing modules. Moreover, I supported deployment of BSR 64000 to support 64+ downstream and upstream channels with full redundancy across all modules.
