As progressive densification of cells, deployment of Cloud-RAN and acMEC\nare coming into reality to support the ultra-low latency with high reliability\nin 5G and beyond, it generates mesh traffic pattern across fronthaul network.\nThis led to evolution of PON architectural enhancements with virtualization in\norder to support such mesh traffic pattern. However, allocation of virtual PON\nslices dynamically over such mesh-PON based fronthaul transport is becoming a\nresearch challenge. In this paper, we provide a mixed analytical-iterative\nmodel to compute optimal virtual PON slice allocation, providing mesh access\nconnectivity with ultra-low end-to-end latency in next-generation MEC-based\nCloud-RAN. Our proposed method can compute optimal virtual PON slice allocation\nin timescales compatible with real-time or near real-time operations.\n
