  Space Division Multiplexed- Elastic Optical Networks using Multicore Fibers
are a promising and viable solution to meet the increasing heterogeneous
bandwidth demands. The extra capacity gained due to spatial parameters in
SDM-EONs could encounter detrimental losses if any link fails and timely
restoration is not done. This paper proposes a Protected and Unprotected
Working Core Groups assignment (PWCG/ UPWCG) scheme for differentiated
connection requests in multicore fiber-enabled SDM-EONs. A PWCG is inherently
protected by resources in a Dedicated Spare Core Group (DSCG). First, we divide
the cores into three groups using traffic and crosstalk considerations. In the
second step, we use the obtained core groups for resource provisioning in
dynamic network scenarios. The effectiveness of our proposed technique is
compared with a Link Disjoint Path Protection (LDPP) technique, and the
simulation study verifies our assertions and the findings.
