This paper presents a performance assessment of signaling protocols with one-way reservation schemes, which are the most used signaling protocols in optical burst switching networks. The analysis is focused on the following topologies: rings, chordal rings, mesh-torus, NSFNET, ARPANET and the European Optical Network. It is shown that these protocols lead to a similar network performance and, therefore, the simplest protocols should be considered for implementation in practical systems. It is also shown that for 16 nodes and 64 data channels, the nodal degree gain due to the increase of nodal degree from two (ring) to three (chordal ring with smallest diameter) is about three orders of magnitude in the last hop of both topologies for any of these protocols. Mesh networks with a number of nodes ranging from 10 to 30 nodes have also been analyzed.
