Projects

  • Fully Interactive Reliable Decentralized Communication System

    • Designed a fault-tolerant and scalable P2P interprocess communication system using Java, implemented vector clock and logic clock timestamp to track events, and a logging application to record logged messages
    • Enabled reliable, causal-ordered multicast messaging in a distributed system, which enhanced the robustness and fault-tolerance of the system; Built a testing application to simulate whether the message would be sent if several nodes crash
    • Developed mutual exclusion service…
