Latency- and Reliability-Aware Reconfiguration of Network Slices in MEC-Enabled 6G Networks

In this paper, we address the problem of reconfiguration of network slices (NSs) to handle network node failures and mitigate service interruptions while satisfying the diverse service requirements of users and multiple industry verticals in beyond 5G and 6G networks. First, we formulate the latency- and reliability-aware NS reconfiguration problem as an integer linear programming (ILP) to minimize resource consumption. Then, to deal with the computational time complexity of ILP, we propose a matching algorithm-based heuristic solution. Through extensive simulations, we show that our proposed algorithm provides a nearoptimal solution in polynomial time with an optimality gap of 2.5% and consumes fewer resources while satisfying stringent latency and reliability service requirements.
