Abstract

The main contributions of this thesis are, firstly, proposing the Bottleneck Congestion Avoidance algorithm and technique that enhances the use of suggestion label in RSVP-TE to reduce the delay and blocking cost during wavelength assignments; secondly, proposing the Traffic Engineering technique that uses explicit routing and the proposed Proper Suggested Label Selection (PSLS) table to distribute the network resources and to provide fast wavelength allocation. This technique also uses the proposed Lambda Blocking Check Algorithm (LBCA) that inexpensively and efficiently checks resources availability through the optical network. The proposed technique enhances the network utilization by reducing the blocking probabilities. (Abstract shortened by UMI.)
