Abstract

As the bi-directional failure notification may cause signaling burst conflict in a short time, a mechanism named single-node failure notification (SNFN) based on RSVP-TE (resource reservation protocol - traffic engineering) is proposed. SNFN implemented by extending the RSVP-TE protocol rules the node issuing the notification signaling call according to ordered numbers, no matter up-stream or downstream. SNFN reduces the blocking probability and improves the restoration performance of the wavelength collision in the GMPLS-based optical network with the data-intensive connections. It can also improve the restoration rate in the cost of tolerable restoration time.
