Abstract

In OBS networks, packets are aggregated into bursts in the edge nodes and then send through the all-optical network to the destination node. Most of the delay phenomenon (variable delay) occurs in the edge node, which is an important issue for the QoS provisioning. The paper characterizes the packet delay in the edge node, which is mainly determined by the burst assembly, transmission queuing as well as the characteristic of the incoming IP traffic
