It is known that the shortest path problem with one or more constraints is NP complete.The paper proposes an improved multi label routing algorithm for ATM networks
which can find an approximate optimal path subject to multiple constraints with arbitrary accuracy in polynomial time scale.For the experimental network of 200 nodes
the numerical results show that the algorithmic loops are reduced to about 1/3 of the original multi label algorithm.
