port routing code

The IALE creates a port routing code in which each bit (marked with a 1) represents a potential destination port

for the frame. This code is modified as it proceeds through the frame-routing algorithm. If the final code is all

0s, then the frame is discarded. If it is not, then the frame is transmitted on every port marked by a 1 within the

code.
