Abstract Developing and evaluating connected and autonomous vehicles mobility is inherently complex. To capture vehicle dynamics, perception and decision-making, and also realistic communication behavior, it requires dedicated simulation environments for traffic respectively, flow modeling, vehicle dynamics, and communication networks. Integrated tool that supports all these capabilities simultan…

Abstract The increasing complexity and volume of modern network traffic, specifically within the context of encrypted Domain Name System (DNS) protocols, particularly DNS over HTTPS (DoH), pose significant challenges to traditional traffic analysis methods, making it difficult to discern legitimate activity from covert or malicious communications. This paper explores the intrinsic self-similarity…

A Service Level Agreement (SLA) is a formal contract between a service provider and a consumer, representing a crucial instrument to define, manage, and maintain relationships between these two parties. The SLA’s ability to define the Quality-of-Service expectations, standards, and accountability helps to deliver high-quality services and increase client confidence in disparate application domain…

Abstract This study utilises publicly available datasets to identify network behaviour patterns in Virtual Network Function (VNF) and Physical Network Function (PNF) traffic. Building on previous research that created the VNFCYBERDATA dataset that focused on VNF traffic, this work compares the VNFCYBERDATA dataset with PNF-based datasets, including CIC-IDS2017 and CIC-Bell-DNS-EXF-2021, as well a…

Abstract Network function virtualization (NFV) is a transformative networking paradigm that leverages virtualization and cloud computing technologies to transform physical network functions, traditionally deployed on proprietary hardware middleboxes, into virtualized network functions (VNFs). This task is achieved by implementing these network functions in software that runs as virtual machines (…

Abstract The Transport Control Protocol has long been the primary transport protocol for applications requiring performance and reliability over the Internet. Unfortunately, due to its retransmission mechanism, TCP incurs high packet delivery delays when segments are lost. To address this issue, previous research proposed to use a novel network function, namely Transport Assistant, deployed withi…
