  Network slicing is a crucial enabler to support the composition and
deployment of virtual network infrastructures required by the dynamic behavior
of networks like 5G/6G mobile networks, IoT-aware networks, e-health systems,
and industry verticals like the internet of vehicles (IoV) and industry 4.0.
The communication slices and their allocated communication resources are
essential in slicing architectures for resource orchestration and allocation,
virtual network function (VNF) deployment, and slice operation functionalities.
The communication slices provide the communications capabilities required to
support slice operation, SLA guarantees, and QoS/ QoE application requirements.
Therefore, this contribution proposes a networking slicing conceptual model to
formulate the optimization problem related to the sharing of communication
resources among communication slices. First, we present a conceptual model of
network slicing, we then formulate analytically some aspects of the model and
the optimization problem to address. Next, we proposed to use a SARSA agent to
solve the problem and implement a proof of concept prototype. Finally, we
present the obtained results and discuss them.
