Key duties and responsibilities:

Design & Development of Routing Protocols 

• Develop and implement network routing protocols such as OSPF, BGP, IS-IS, RIP,
• EIGRP, and MPLS.
• Enhance and optimize routing algorithms for performance, scalability, and reliability.
  
• Work on control plane software for Virtual Service Routers (VSR)

Protocol Optimization & Performance Tuning 

• Improve routing efficiency to reduce latency, packet loss, and congestion. 
• Optimize dynamic routing to adapt to changing network conditions in real time.
• Implement load balancing and redundancy techniques (e.g., ECMP, fast reroute).

Network Software Development & Integration 

• Develop software for Software-Defined Networking controllers. 
• Integrate with network operating systems (NOS) such as FRRouting (FRR).
• Work with open-source networking stacks (e.g., Quagga, BIRD, VyOS).
