6. Developed polynomial time algorithms for protocol pruning and network gateway synthesis, and applied them to real complex protocols such as TCP/IP and ATM protocols with a run time of only a few minutes, while it was impossible for the previous exponential time algorithms.
7. Provided formal specifications of ATM protocols and contributed to ATM Forum. Analyzed the correctness and performance of and also generated test sequences for ATM traffic management protocol.

  • All-optical network protocol and software system design and implementations
    1. Applied optimization, game theory and coding theory to all-optical network lightpath protection and restoration to significantly increase the efficiency and reliability.
    2. ONMP (Optical Network Management Protocol), a management protocol system for Lucent Lambda Router networks. It is one of the first working system in the industry for lightpath provisioning with the following functions:
    (i) Lightpath computation;
    (ii) Lightpath setup and teardown;
    (iii) Shared lightpath protection and restoration;
    (iv) Automatic neighbor and resource discovery;
    (v) Distributed signaling system;
    (vi) Automated fault management.
    3. Invented a new signaling protocol - Lazy Flooding - to prevent or reduce the congestion in the signaling network to improve the performance, reliability and scalability of the all-optical networks.
