It would seem that "blocking probability" is an attribute of
connection-oriented networks and has no relevance to a connectionless
network protocol like IP.   In short, except for transient effects, the
"blocking probability" of Internet routing is defined to be exactly zero
(or else 100%, for traffic disallowed by firewalls, etc.)
