Summary
🤩
Rockstar🎓
Top SchoolAshok Daparthi is a senior network development engineer with 11+ years building high-performance data center switching and routing software, currently leading forwarding-plane development and QoS for Dell/Force10 platforms. He brings deep embedded C and system programming expertise across Broadcom-based NPUs, MMU tuning, WRED, hierarchical QoS, DCB (PFC/ETS/DCBX) and CoPP, pairing protocol-level insight with hands-on deployment experience on S and Z family TOR and chassis switches. Ashok has driven multicast and control-plane features from IGMP/PIM/MLD implementations to production multicast table programming and high-availability behavior on large chassis systems. As a maintainer of SAI-related forwarding modules, he contributed QoS and Energy Efficient Ethernet attributes to the Open Compute Project’s Switch Abstraction Interface, bridging open-source abstractions to vendor SDKs. Based in California, he is a practical problem-solver who routinely tunes MMU and DCB thresholds for storage workloads, improving throughput and latency in real customer environments.

Contributions summary:Ashok's primary contribution focused on adding support for Quality of Service (QoS) features to the Switch Abstraction Interface (SAI). This included implementing functionality for policers, queues, schedulers, scheduler groups, and WRED (Weighted Random Early Detection). Furthermore, the user introduced attributes for the port, switch, and buffer to enable EEE (Energy Efficient Ethernet) functionalities. These changes expanded the SAI's capabilities for traffic management and power efficiency.
