• Developed AMF (SAF core service) in close interaction with SA Forum working group. The middleware transformed into an open-source project led by companies like Emerson, Ericsson, HP, Oracle, IP Infusion, Tail-f, MontaVista etc.
• Recruited new members as a part of middleware team expansion program. Mentored them and coordinated their efforts in various enhancements.
• Developed demos for various shows utilizing HA middleware capabilities - HA video streaming application (Supercomm’04) & SIP demo (Supercomm’05 & 3GSM’05).
• Prototyped a sample application (demonstrating AMF & SAF Checkpoint service) that was used by the technical marketing team for various customer engagements.
• Performed impact analysis on middleware of new ATCA compliant boards in collaboration with the architecture team.

Jun 2001 – Feb 2003 · 1 yr 8 mos · Hyderabad, Telangana, India

• Refactored existing BGP implementation to make it modular and address family independent. This enabled future BGP enhancements (MP-BGP, L3VPN etc.). Memory utilization and performance also improved allowing BGP to scale to Internet routing table size.
• Enhanced BGP with various features - Capabilities Advertisement, Graceful Restart, Route Refresh etc. MP-BGP support was added to support BGP L3VPN address family (for BGP-MPLS L3VPN effort).
• Analyzed new IETF drafts (related to BGP) & gave inputs to the team. Represented Netplane in 56th IETF session (held in SanFransisco).

• Involved in Functionality, Interoperability & Compliance Testing of OSPF implementation.
• Worked on several OSPF enhancements including Opaque LSA support that served as the basis of OSPF-TE capability for GMPLS.
• Imparted hands-on training for a batch of ~50 fresh hires.
• Enhanced in-house TCP implementation with extensions to improve performance over LFNs (long fat networks). This included TCP options like Selective ACK, Negative ACK, Timestamp and Big Window.
• Also exposed to various TCP algorithms like Increased Initial Window, Slow Start & Congestion Avoidance, Fast Retransmit & Fast Recovery etc.
• Early exposure to IP Routing and TCP (along with system exposure) helped me get a head start into my professional journey.
