> If you haven't heard of Zaw-Sing, I think he started to work on pieces of the Internet in the 70s. While at UCLA, he worked on tasks for the packet radio program involving simulation and  taking measurements of the experimental network. I think he then came to SRI where he wrote RFC 781 (IP Timestamp Option) and became a key contributor to DNS. He also worked on the design approach used in the Reconstitution Protocol project.  After SRI, I believe he went to Telenor and unfortunately that is where I lost touch with him. I am sure he did much more as this is just the little I know. I hope some of you also had a chance to talk to him about his experiences growing up in China.
