A. Blocking Time
The blocking time, which is the time a message must wait
once a node is ready to send it, depends on the network
protocol and is a major factor in the determinism and
performance of a control network. It includes waiting time
while other nodes are sending messages and the time needed to
resend the message if a collision occurs.
The blocking time for Ethernet is considered first, which
includes time taken by collisions with other messages and the
subsequent time waiting to be retransmitted. The standard
