Title
Blocking Analysis in Hybrid TDM-WDM PONs Supporting Elastic Traffic
Abstract
The Passive Optical Network (PON) is an attractive solution for delivering services with numerous applications, such as high-definition video, video conferencing and data traffic. In this paper we develop teletraffic loss models for calculating connection failure probabilities (due to unavailability of a wavelength) and call blocking probabilities (due to the restricted bandwidth capacity of a wavelength) in hybrid TDM-WDM PONs with dynamic wavelength allocation. We consider either stream or elastic traffic. The proposed models are derived from one-dimensional Markov chains which describe the service system in the PON. The wavelengths occupancy in the PON is also provided. The accuracy of the proposed models is validated by simulation and was found to be quite satisfactory.
