Intelligent and Resource-Conserving Service Function Chain (SFC) Embedding

2023 , Journal of Network and Systems Management
Network Function Virtualization (NFV) opens us great opportunities for network processing with higher resource efficiency and flexibility. In this respect, there is an increasing need for intelligent orchestration mechanisms, such that NFV can exploit its potential and live up to its promise.…

Unsupervised Deep Learning for Distributed Service Function Chain Embedding

2023 IEEE Access
Network Function Virtualization (NFV) has paved the way for the migration of Virtual Network Functions (VNFs) into multi-tenant datacenters, lowering the barrier for the introduction of new processing functionality into the network. Recent trends for resource orchestration across the entire compute…

Deterministic and Probabilistic P4-Enabled Lightweight In-Band Network Telemetry

2023 IEEE Transactions on Network and Service Management
In-band network telemetry (INT), empowered by programmable dataplanes such as P4, comprises a viable approach to network monitoring and telemetry analysis. However, P4-INT as well as other existing frameworks for INT yield a substantial transmission overhead, which grows linearly with the number of…

IRIS: Interference and Resource Aware Predictive Orchestration for ML Inference Serving

2023 - IEEE Cloud (International Conference on Cloud Computing)
(THIS PAPER RECEIVED THE BEST PAPER AWARD OF 2023 IEEE CLOUD). Over the last years, the ever-growing number of Machine Learning (ML) and Artificial Intelligence (AI) applications deployed in the Cloud has led to high demands on the computing resources required for efficient processing. Multiple…

Towards the Integration of TAPRIO-based Scheduling with Centralized TSN Control

3rd International Workshop on Time-Sensitive and Deterministic Networking (TENSOR 2023) – IFIP Networking 2023
Time-Sensitive Networking (TSN) aspires to provide a solid underpinning for meeting latency guarantees across traffic classes with diverse requirements. Despite the emergence of various specifications from the TSN family of standards, there is a shortage of prototype implementations with support…

On the Implications of Heterogeneous Memory Tiering on Spark In-Memory Analytics

2nd Workshop on Composable Systems (COMPSYS2023)
This study considers a multi-tier heterogeneous DRAM/NVM memory system with contrasting access latency, bandwidth and energy consumption capabilities. The paper examines the implications of heterogeneous memory tiering on Spark in-memory analytics and addresses the challenge of the growing demand…

The Cloud-to-Edge-to-IoT Continuum as an Enabler for Search and Rescue Operations

JOURNAL - Future Internet 2023, 15(2), 55 (Special Issue “Moving towards 6G Wireless Technologies”)
When a natural or human disaster occurs, time is critical and often of vital importance. Data from the incident area containing the information to guide search and rescue (SAR) operations and improve intervention effectiveness should be collected as quickly as possible and with the highest accuracy…
