We study and evaluate the performance of three potential candidates of resource-sharing algorithms in agile single-hop slotted buffer-less all-optical packet switched metro networks. Both reservation-based (centralized) and collision-based (distributed) schemes are considered. In the centralized scheme, all decisions are made at the core switch and loss can be avoided through reservations. On the other hand, decisions are made at the edge switches in the distributed scheme, and we need to retransmit the dropped traffic. We also implement an integrated architecture that combines the good attributes of both schemes and characterize this architecture by various measures such as delay and loss probabilities at the edge switches.
