Abstract
In IP networks, coarse packet classification is a scalable QoS solution. Similarly, it can also be utilized to an OBS network. In order to match IP QoS requirements with the data processing capacity and flexibility of OBS networks, we propose a novel optical burst assembly technique, which is based on mapping rules and a dynamic threshold mechanism called ATQ-DT. How to map the IP QoS to burst priority is resolved by the mapping rules, and how to efficiently allocate the assembly capacity among classes belonging to the same priority is answered by ATQ-DT. This mechanism determines the maximum share for each class, which is proportional to the current unused capacity. Among the three mapping rules we propose, TQ-MAP is the most reasonable one because it considers both the traffic condition and the QoS requirement. As shown by simulation results, the assembly technique ATQ-DT with TQ-MAP can most remarkably improve the packets loss probability (PLP) to support QoS.
