“…Basically FDL buffers can be categorized into two types: 1) the feed-forward-type (FF) buffer [12,13] and 2) the feedback (or recirculation)-type (FB) buffer [6,7]. In the FF buffer, the contending burst is forwarded to a pre-fixed length delay line and then it leaves the buffer regardless of its success or failure in accessing the output resource.…”

“…According to the position of buffers, they can be further classified into 1) the dedicated to wavelength type [12], 2) the shared per port type [13], and 3) the shared per node type [7]. In a buffer dedicated to a single output wavelength, more than two bursts attempting to access the same wavelength can be delayed during the contending time.…”

“…Burst contention resolution is one of the key issues in transparent optical networks [2,6,7,8,9]. The burst contention occurs when more than two data bursts attempt to access the same output resource simultaneously.…”

“…The burst contention occurs when more than two data bursts attempt to access the same output resource simultaneously. There have been proposed several contention resolution technique, such as the use of wavelength converters [6], optical buffers using fiber delay lines [6,7], deflection routing [8], burst segmentation [9], and so on. Among these techniques, optical buffer provides a more appropriate method to reduce high burst loss rate since it fundamentally resolves contention by intentionally delaying the blocked burst during the contending time as in conventional networks.…”

This paper proposes a novel service differentiation mechanism utilizing optical buffers in transparent optical networks. We first introduce fiber delay line (FDL)-based optical buffers and propose a hybrid shared optical buffered node. Based on the proposed buffer, diverse service requirements can be satisfied by assigning different priorities on accessing the buffer. Since the blocking performance is affected by the basic delay unit of FDL represented by a ratio of the burst length, this paper also takes into account the effect of the burst assembly process on the buffer performance. By dynamically adjusting the burst length under the changing traffic load, optimal performance of the proposed optical buffer can be achieved. Our simulation results show that diverse service requirements can be satisfied in terms of burst blocking probability and buffering delay time.

Optical burst switching (OBS) is a very promising switching technology of the optical networks. In OBS networks, when contention occurs at an intermediate core switch, the bursts that are in contention will be dropped if no appropriate contention resolution scheme is applied. In this paper, we propose an Edge Buffer Based Contention Resolution (EBR) Scheme, which mitigates and resolves contention by deflecting the contending bursts to the electronic buffer of the schedule module in the edge node which is directly connected with the core switching node. We have simulated EBR scheme under selfsimilar traffic and the simulation results indicate that our scheme has a significantly good performance on decreasing the burst dropping rate and its simplicity makes it convenient to collaborate with other contention resolution schemes.
