Abstract

One of challenges to efficient utilizing network resources is to design an effective lightpath teardown strategy in IP/MPLS optical networks. In the traditional integrated routing schemes, a lightpath is established optimally for a LSP request, but may not remain optimal for future requests. Releasing the suboptimal lightpath may free wavelength resources to prepare for new optimal lightpath establishment. In this paper, we proposed and evaluated three lightpath path strategies, threshold-based period-based and no lightpath teardown strategies in a comprehensive distributed simulation platform for IP-MPLS over optical networks within the generalized MPLS (GMPLS) framework. The simulation results show that TBLTS and PBLTS achieve shorter-length paths and at low load, and TBLTS outperforms the other two in terms of blocking probability. In addition, CR-LDP also can get significant performance advantages than RSVP-TE signaling protocol.
