Previous studies on routing and wavelength assignment
algorithms assumed that the global link state information is obtained
without delays and route is selected adaptively. However, in
distributed lightpath establishment, if sender nodes select the route
adaptively, the blocking probability increases because of the delayed
link state information. On the other hand, with alternate routing
algorithm, the sender node selects next route in pre--defined routes
if path setup fails. Therefore the performance degradation is small
in alternate routing. In this paper, we evaluate the average path
setup time for routing algorithms in distributed networks to clarify
the effect of delayed link state information. The simulation results
show that an adaptive routing algorithm (least loaded algorithm) is
much affected by the delayed link state information. The results also
show that a new routing algorithm (FAR with 1SP and LL) performs
better than other routing algorithms, especially in the distributed
environment. |
