“…Simulation tests were done for the CLDR algorithm and Shortest Path-based Deflection Routing (SPDR) algorithm which has been generally used in other known works [3]- [5]. In our simulation, the JET method of offset-based reservation is used and the burst sources were individually simulated with the on-off model as explained in the Queueing Model section.…”

“…In [3] and [4], it is demonstrated via simulation tests that the blocking probability improves when deflection routing is used as a means for contention resolution. The authors of [5] describe how deflection routing can be used in conjunction with the self-routing address scheme. However, they do not address the issue of how routing to an alternate path should be done, given that some constraints may apply to the selection of an alternate path.…”

“…While several variants of the basic deflection routing scheme have been proposed before [2]- [5], they all lacked the ability to determine the alternate route based on clear performance objectives. In this paper, we present an on-demand deflection routing scheme, which sequentially performs the following: (1) based on certain performance criteria, dynamically determines if the burst should be deflection routed or retransmitted from source, (2) if the decision is to deflection route, then the same is done using a path that is based minimization of a performance measure that combines distance and blocking due to contention.…”

One of the critical design issues in Optical Burst Switching (OBS) networks is finding ways to minimize burst dropping resulting from resource contention. The existing variants of the basic deflection routing schemes all lack the ability to determine the alternate route based on clear performance objectives. In this paper, we present Contention-Based Limited Deflection Routing (CLDR) scheme, which sequentially performs the following: (1) based on certain performance criteria, dynamically determines if the burst should be deflection routed or retransmitted from source, (2) if the decision is to deflection route, then the same is done using a path that is based on minimization of a performance measure that combines distance and blocking due to contention. Through analytical and simulation modeling, a number of useful insights into the OBS network protocols and performance are provided.

“…Several contention resolution techniques have been proposed such as optical buffering, wavelength conversion, and deflection routing. Due to the immaturity in both optical buffering and wavelength conversion techniques, deflection routing has received a lot of attention most recently [3][4][5][6]. Thus, when a control packet encounters a contention at a given node over the primary path, the deflection routing procedure implemented in each switch automates the alternative path setups.…”

Optical Burst Switching (OBS) is a very promising technology for the next generation of optical Internet. In OBS networks, contention caused by multiple bursts competing simultaneously for a given wavelength on a fiber link, significantly increases the burst dropping probability and hence deteriorates the overall network performance. That is the reason why finding solutions in order to minimize burst dropping due to resource contention is one of the critical design issue in OBS. This paper proposes and analyzes three new deflection routing strategies that resolve contention with significantly better performance compared to the previous ones that have been previously proposed. One of the drawbacks of the deflection routing mechanisms presented in the literature is their lack of flexibility for computing the alternative paths based on some clear design constraints. The proposed deflection strategies are based on different alternative path computing methods with a burst dropping anticipated feature: (i) Least loaded node (LLN), (ii) LLN/U-turn and (iii) LLN/U-turn with load balancing. Simulation was conducted on the Pan-European COST 266 optical network to analyze the proposed strategies.
