“…And FDL method may increase the Manuscript packet delay and change the packet order in receiver [1]. The deflection routing method resolves collision by selecting the alternative routing in mesh network, which increases network load largely [2]. Wavelength converter resolves the collision by converting the colliding packet to an idle wavelength in the wavelength domain without time delay.…”

Optical multicast collision occurs more frequently for the replication and forwarding of optical multicast increase in the switch node. In this letter, an optical multicast switching node architecture configured with wavelength conversion and network coding is proposed. The proposed node architecture uses a group of output shared wavelength converters in the wavelength domain and a group of feedback shared encoders to resolve the optical multicast collision. To minimize the total conversion degree, we propose an improved algorithm, maximal weighted stable set, to assign wavelength converter with respect to the wavelength conversion degree as the weight. Concretely, the graph coloring matching algorithm is used to select the wavelength converter with minimal wavelength conversion degrees. Compared with the node architecture with two layers wavelength conversion and with full range wavelength conversion, analyses and simulation results show that the proposed node architecture largely reduces the packet loss probability with low cost of wavelength conversion and results in a better performance to solve multicast collision.Index Terms-All-optical multicast switch, limited range of wavelength converter, network coding, packet scheduling.

Optical burst switching (OBS) is an optical switching technology; it uses an optical fiber's high bandwidth potential to transfer huge amounts of data in the form of huge packets, which are more commonly referred to as bursts. High burst loss brought on by numerous burst contentions is a significant problem in OBS. An intelligent fuzzy offset time algorithm (FOT) algorithm is suggested to overcome this problem. This study proposed Intelligent Fuzzy Offset Time (FOT) algorithms that adjust offset time (OT) in accordance with network and traffic conditions. The fuzzy input for FOT is made up of three parameters: burst size, distance, and time that burst spent in queuing. The suggested algorithm is assessed versus the Intelligent OT algorithms using the Five defuzzification techniques (Centroid (CM00), Bisector (BM04), largest of maximum (LM02), smallest of maximum (SM03), and mean of maximum (MM01) when Maximum (M) accumulation technique is used, when using Algebraic Sum (S) aggregation methods (Centroid (CS00), Bisector (BS04), largest of maximum (LS02), smallest of maximum (SS03), and mean of maximum (MS01). Simulation results have shown that FOT LM02, FOT LS02, FOT SM03 and FOT LS02 have effects on reducing BLR (burst loss ratio) and E2E (End-2-End) delayed respectively when compared to other defuzzification techniques algorithms. FOT LM02 and FOT SM03 can be used to intelligently adjust the offset parameter using the incoming traffic load and the three parameters.
