Headed the architecture for Security infrastructure and hardening the gateway (LTE and Wimax). This involved working across various cross functional business units. Focus on buffer overflow, starvation and resource contentions. Fixed various deadlocks in the IP stack/network data path in the kernel.
Implemented the Network Monitoring and Maintenance system (NNMS), which monitors all the gateways in the customer network, if any issues found during the health check, corrective action is taken by the NMMS based on the severity of the issue. KPI based management of the wimax gateway is also handled by NNMS.
Improved the overall code to provide 400 days MTBF from less than 72 hours of MTBF.
Received "Tellabs Excellence Award" for my contribution.
