Abstract :
A new class of quality of service (QoS) measures, EB(p), p≥1 for WDM optical transport networks is proposed in this paper. Compared with the traditional overall average blocking probability (OABP), EB(p) is a composite measure that is unbiased, makes reference to the QOS requirements, one-sided, and takes the potential revenue loss into consideration. In particular, EB(1) can be identified as (revenue) weighted average excessive blocking, and EB(2) as mean square (revenue) weighted excessive blocking. The effectiveness of this new composite measure is compared with OABP based on several existing routing and wavelength assignment algorithms.
