Optical Burst Switching (OBS) appears to be the new generation of optical internet backbone infrastructure, because of its attractive characteristics. It has a combination of advantages stemming from both the packet switching and circuit switching methods. Therefore, further research which highlights the features of OBS should be provided. In this paper, a detailed survey on OBS networks is conducted, as well as discussions on the characteristics and signaling parameters of the OBS. The survey highlights the advantages of an OBS network, making it the rational choice for building the next-generation internet backbone. Additionally, an investigation is conducted into the effect of the signaling protocols Tell-And-Go (TAG) and Tell-And-Wait (TAW) on the packets delay. The investigation results indicate that the TAG protocol is better than TAW regarding packets delay, making it a better choice for real time traffic over OBS.
