Abstract

The explosive growth of traffic on the backbone of the Internet reflects advancements in technologies that make it possible to popularize highbandwidth, low-latency network applications. However, traffic growth and network capacity are rarely compatible. In this sense, the Spatial Division Multiplexing technology in Elastic Optical Networks has shown to be quite promising due to its capacity expansion and requests adjustment properties. This paper proposes a modulation, spectrum, and core allocation and routing algorithm for SDM-EON, focusing on reducing the request blocking rate via medium crosstalk and fragmentation reduction strategies. The results obtained demonstrate the high efficiency of the proposed algorithm in establishing connections compared to similar algorithms in the literature.
