Staff Software Engineer

Mar 2015 – Oct 2019 · 4 yrs 7 mos

Traffic Domain – Citrix ADC
Contributed to the design and implementation of the Traffic Domain feature for Citrix ADC, enabling VLAN based multi-tenancy. The solution ensured complete configuration and traffic segregation by associating system resources with tenant-specific VLAN IDs, enhancing isolation and scalability within shared environments.
Software Cluster
Worked on Packet steering logic within a clustered, multicore ADC system. Leveraged RSS-based distribution using four-tuple identifiers to ensure packets are routed to the correct node and core, enabling support for protocols like FTP and preserving client IP/port consistency across cluster nodes.

L2 Device Load Balancing:
Designed and implemented Layer 2 device load balancing on Citrix ADC using VLAN and MAC-based policies, enabling traffic distribution without relying on Layer 3 or 4 configurations.
Connection Mirroring:
Developed connection mirroring functionality for FTP and NAT sessions to maintain session persistence and seamless recovery during high availability failovers.
Port Control Protocol (RFC 6887):
Implemented support for Port Control Protocol to allow host-level control over port forwarding rules, aligning with RFC 6887 for IPv4/IPv6 environments.
Forwarding Session
Developed a mechanism to differentiate and forward traffic between clients and branch repeaters using MAC-based session identification while ensuring proper load balancing.
IP-in-IP Tunnel (RFC 2003)
Implemented IP-in-IP tunnel support to enable encapsulated communication between Citrix ADC and backend server farms, adhering to RFC 2003 specifications.
ARP, IPv4, TCP, IPv6, ND6 – Citrix ADC (NetScaler)
Worked on core networking protocol features (ARP, IPv4, TCP, IPv6, ND6) on the Citrix NetScaler platform. Contributed to IPv6 support and stability improvements by delivering critical bug fixes and protocol enhancements. Played a key role in maintaining and extending low-level networking functionality in a performance-sensitive, production-grade system.
