Optical Burst Switching (OBS) is a new switching technology for next generation optical internet. In this paper we describe the design and implementation of Just Enough-Time Domain level Signalling (JET-DS), a new signalling protocol for hybrid control architecture of OBS control plane. The important features of JET-DS framework are its hybrid control signalling that supports end-to-end reservation of centralized and one-way reservation of distributed architectures, delayed reservation that efficiently utilizes network resources and flexibility that supports both guaranteed as well as best effort lightpath establishment schemes. We also present different lightpath establishment operations of JET-DS. Finally we compare the proposed protocol with JIT and WR-OBS.
