Optical burst switching (OBS) supports IP-over-photonics for future QoS-supporting Internet through combining advantages of electronic control processing and optical transmission. The resource reservation is critical for OBS. In this paper we examine optical burst switching (OBS) reservation process and discuss the most important parameters and their impact on the performance of the reservation process. A general framework for its modeling and analysis is presented. We model OBS reservation using queueing networks. Our framework and model cover all aspects of OBS reservation process including control packet arrival, offset time assignment. control packet processing, optical switch matrix setup, data burst arrival and transmission. Current models and analysis only consider offset time assignment and data burst arrival and transmission its OBS reservation. Further we show that even though widely assumed and used, conservation law does not hold generally for average burst loss probability for reservation processes which support multiple priority classes.
