Data-Driven Online Slice Admission Control and Resource Allocation in NextG Mobile Networks
Muhammad Sulaiman, Bo Sun, Mohammad Ali Salahuddin +2
Virtualization in 5G and beyond networks enables the creation of virtual networks (i.e., network slices) tailored to the needs of different applications. To maximize revenue under…
Risk-Sensitive Online Selection with Bounded Adaptivity
Hossein Nekouyan, Bo Sun, Raouf Boutaba +1
Designing randomized online algorithms that perform reliably not only in expectation but also under unfavorable realizations of randomness is a fundamental challenge in online deci…
HyRA: A Hybrid Resource Allocation Framework for RAN Slicing
Mohammad Zangooei, Bo Sun, Noura Limam +1
The advent of 5G and the emergence of 6G networks demand unprecedented flexibility and efficiency in Radio Access Network (RAN) resource management to satisfy diverse service-level…
RAID: In-Network RA Signaling Storm Detection for 5G Open RAN
Mohamed Rouili, Yang Xiao, Sihang Liu +1
The disaggregation and virtualization of 5G Open RAN (O-RAN) introduces new vulnerabilities in the control plane that can greatly impact the quality of service (QoS) of latency-sen…
Towards Sub-millisecond Latency and Guaranteed Bit Rates in 5G User Plane
Leonardo Alberro, Noura Limam, Raouf Boutaba
Next-generation services demand stringent Quality of Service (QoS) guarantees, such as per-flow bandwidth assurance, ultra-low latency, and traffic prioritization, posing significa…
Rethinking Telemetry Design for Fine-Grained Anomaly Detection in 5G User Planes
Niloy Saha, Noura Limam, Yang Xiao +1
Detecting QoS anomalies in 5G user planes requires fine-grained per-flow visibility, but existing telemetry approaches face a fundamental trade-off. Coarse per-class counters are l…
