Pushpasis Sarkar is a Principal Architect specializing in routing and network control-plane software with over two decades of engineering experience and 11 years focused on advanced networking products. He has driven core routing features—BGP (including MP-BGP, L3VPN, SR-TE), ISIS, OSPFv3, FRR scalability, and fast-reroute techniques—across major vendors including Juniper, Cisco, VMware and now Aviatrix. Known for shipping high-impact protocol implementations (Remote-LFA, SR-in-ISIS, ISSU/NSR support) he blends standardization work at IETF with production-grade engineering that has helped win customer deals. At VMware he led efforts to scale FRR to millions of paths and introduced a YANG-based management framework, reflecting a rare mix of protocol theory and systems engineering. Based in Bengaluru, he mentors and technically leads teams through complex routing challenges and contributions back to open-source routing stacks. Beyond core routing, his early work spans telecom systems and DPDK-based packet forwarding, showing breadth from low-level dataplane prototypes to orchestration-scale control-plane design.
