A subscription-based two-way signaling for optical burst switched networks

Abstract

Optical burst switching (OBS) is a promising all-optical switching mechanism and signaling is one of the key technologies of optical burst switched networks. According to the propagation direction of control packets, an existing OBS signaling can be classified as one-way or two-way signaling. The transmission of bursts in two-way signaling is guaranteed while in one-way signaling is unguaranteed, so the blocking rate in two-way signaling is less than in one-way signaling. But the end-to-end delay and operation complexity in two-way is greater than in one-way signaling. In this paper, we propose another two-way signaling named subscription-based tell-and-wait (S-TAW), which is a forward reserved, delay-configured and implicitly released two-way OBS signaling. By analysis and simulation, we show that S-TAW can reduce the operation complexity and end-to-end delay without greatly increasing the blocking rate, comparing with the existing best-performed two-way signaling—prebooking reservation mechanism.
