Abstract：A novel crank back mechanism based on re-routing in crank back node is proposed in ASON. This mechanism avoids the flow of crank back message when the crank back happened in connection establishment. To support this mechanism, function of component and procedure of signaling perform are extended. A test-platform of 15 nodes is built, it implement control plane of ASON by running RSVP-TE, OSPF-TE and LMP etc. The experimental results show that new mechanism has less connection setup time and network traffic than the traditional mechanism has.
