The path selection with bandwidth and delay constraints in IP networks was researched. Two algorithms were proposed for QoS routing with bandwidth and delay constrains based on traffic engineering. By computer simulation, the probabilities of the algorithms in the networks were compared with the same topology and different link bandwidths. The result showed that SEDPF algorithm was better than others.
