PROFILE
Carmine Scarpitta
Carmine Scarpitta enhanced the sonic-net/sonic-swss repository by delivering two targeted features over two months, focusing on IPv6 link-local SID programming and SRv6 test reliability. He implemented a parsing update in C++ to extract both nexthop IPv6 addresses and interfaces, enabling correct ASIC programming for link-local adjacencies and improving network stability. Additionally, he improved SRv6 test accuracy by adopting static SID CLI configuration in Python, aligning tests with the FRR workflow and reducing kernel-based workarounds. His work demonstrated depth in network programming, test automation, and cross-component integration, resulting in more reliable routing and streamlined continuous integration processes.

Nov 1, 2025November 2025: Delivered a critical uA SID programming enhancement for link-local IPv6 resolution in sonic-swss (repo sonic-net/sonic-swss). The change extracts both the nexthop IPv6 address and the interface, enabling correct SID programming in the ASIC for link-local adjacencies. Implemented parsing updates and added tests to validate functionality, ensuring end-to-end path from FRR to fpmsyncd to OrchAgent. Fixed a bug in fpmsyncd/OrchAgent where missing interface data caused SID programming failures, improving reliability and reducing MTTR for adjacency updates. This work strengthens network stability for IPv6 link-local routing, reduces risk of dropped paths, and demonstrates strong cross-component collaboration across FRR integration, test-driven development, and ASIC programming. Technologies: C++, Python tests, FRR FPMSyncD, SRV6_MY_SID_TABLE, OrchAgent; skills: debugging, parsing, test automation, and cross-team collaboration.
