[e2e] Folklore of protocol design

[Xiaoming Fu]

  Hi,
I enjoyed Radia Perlman's keynote at SIGCOMM yesterday who introduces 
several key aspects of protocol design - thanks! Besides the two 
graceful "algorithms" she proposed in the talk, I think there is an 
additional reading for anyone of interest that she wrote more than a 
dozen years ago: http://tools.ietf.org/id/draft-iab-perlman-folklore
