Worked on multicast TTL improvements to enhance routing reliability and deployment scalability across the firedancer and agave repositories. Addressed multicast routing in firedancer by setting the IP_MULTICAST_TTL to 64 on transmission sockets in socket mode, ensuring packets could traverse beyond local subnets. In agave, introduced multicast TTL support through a configuration-driven approach, propagating TTL settings to UDP sockets at the node level. These changes, implemented using C and Rust with a focus on network and socket programming, aligned TTL handling across the codebase, reduced operational risk, and enabled more robust and scalable multicast workflows for distributed Linux deployments.
