“…Furthermore, the presented OBS architecture brings additional profit like dismissing the offset variations with the related unfairness problem in access to transmission resources [10]. Indeed, in conventional OBS networks, whilst the control packet travels through the network its OT decreases successively at each hop by the PT.…”

Abstract-Burst preemption is the most effective technique to provide Quality of Service (QoS) differentiation in Optical Burst Switching (OBS) networks. Nonetheless, in conventional OBS architectures, when preemption happens the control packet corresponding to the preempted burst continues its travel to the destination node reserving resources at each node of the path. Therefore, an additional signaling procedure should be carried out to release these unnecessary reservations. In this paper we present novel control architecture to efficiently apply burst preemption without the need of the signaling procedure. Analytical and simulation results prove the effectiveness of this proposal.

“…Consequently, in BLD method, HP class is assigned shorter burst lengths than the LP class for enhancing the performance of the HP class relative to the LP class in terms of loss probabilities. In particular, HP packets are burstified using lower timer [10] and lower burst length thresholds [8,10] compared with the corresponding values for LP packets (see Fig. 5).…”

“…Moreover, the end-to-end delay for HP traffic increases as a result of increased offset times which, in turn, decreases the throughput. [10]. The Burst length-based differentiation (BLD is another edge based mechanism that has been explored quite extensively.…”

“…Further more; use of a shorter burstification timer for the HP class correspondingly is to reduces the overall end-to-end delay. BLD can also be used as a complementary method in conjunction with another differentiation mechanism, such as OTD, for improved isolation between traffic classes [10]. However its draw backs include the increase in complexity of the burst assembly unit coupled with an increase of signaling overhead.…”

Abstract-All-optical networks (AON) based on optical burst switching (OBS) are rapidly becoming the ultimate backbone network solution for next (future) generation networks because of their potential ultra high bandwidth capacities both at transmission and switching levels. The OBS switching paradigm was conceptualized and ultimately designed using the good features of both optical circuit switching (OCS ) and optical packet switching (OPS) and thus provides improvements over wavelength routing in terms of bandwidth efficiency, at the same time eliminating the need for huge buffers at the network edges as well as optical -to-electronic conversions and vice-versa of the data bursts at the core (switching) nodes. With such networks end to end light channels will transmit users data , transparently i.e. without being aware of its bit rate, modulation format as well as network protocol thus enhancing capacity, flexibility and scalability of the network. A buffer less /limited buffered lead OBS network would mean high contention and blocking, hence to guarantee and end-to-end consistent QoS in would require that the resources are properly managed. Effective management of both control and data planes is a key issue in this regard. Thus in this paper, we propose and analyse a partial distributed resource management scheme for OBS networks. We describe the concept, followed by routing and wavelength selection procedures.

“…Erlang's well-known B formula was used to obtain the burst blocking probability, with the assumption that the DBs arrive in Poisson stream [4]. Similarly, this queuing model can be extended to model SRS to have a simple projection of the scheme's performance improvement over the traditional OBS.…”

Abstract:In this paper, the Staged Reservation Scheme (SRS) is introduced for Optical Burst-Switched (OBS) networks based on JustEnough-Time (JET) protocol. With SRS the Data-Bursts are segmented into equal sub-bursts (data segments). SRS is to address the feasibility issues (e.g. segments delineation, and trailer-messages creation) associated with the implementation of burst segmentation techniques. The burst control packet is modified to carry the segments' number and length, therefore the data-bursts length. Furthermore, the network resource reservation is performed in stages to resolve contentions at the control packets level, and to reduce the packets loss probability.
