A most elegant TCP hole punching algorithm
The algorithm in this post needs “double buckets” to be reliable. Otherwise, the two sides can split on bucket boundaries and fail to converge. If the first bucket fails, compute an additional bucket step for convergence. My algorithm trades slow startup for less infrastructure.
