Multiple connections interacting...

Current connection i

New connection j

The entire network needs to be re-evaluated!

Di(w),Qi(w)

Di(x),Qi(x)

connection i’s delay: ...+ Di(w) + Di(x) + ...

Di(w) changes ==> connection i’s delay changes

Qi(w) changes ==> Di(x) changes --- conn j ‘s delay changes

Current connection k
