OKpi: All-KPI Network Slicing Through Efficient Resource Allocation
Jorge {Mart\'in-P\'erez}, Francesco Malandrino, Carla Fabiana, Chiasserini, Carlos J. Bernardos

TL;DR
OKpi is a novel resource allocation scheme that efficiently manages multiple KPIs across network and computing resources, supporting diverse services from fog to cloud with near-optimal performance.
Contribution
It introduces a comprehensive methodology for joint KPI-aware resource allocation, addressing newly considered KPIs like availability and reliability, which were neglected in prior works.
Findings
OKpi achieves near-optimal resource allocation performance.
It supports multiple KPIs simultaneously with polynomial complexity.
Validated in real-world scenarios, it closely matches optimal solutions.
Abstract
Networks can now process data as well as transporting it; it follows that they can support multiple services, each requiring different key performance indicators (KPIs). Because of the former, it is critical to efficiently allocate network and computing resources to provide the required services, and, because of the latter, such decisions must jointly consider all KPIs targeted by a service. Accounting for newly introduced KPIs (e.g., availability and reliability) requires tailored models and solution strategies, and has been conspicuously neglected by existing works, which are instead built around traditional metrics like throughput and latency. We fill this gap by presenting a novel methodology and resource allocation scheme, named OKpi, which enables high-quality selection of radio points of access as well as VNF (Virtual Network Function) placement and data routing, with polynomial…
