Deep Learning for DSCP Manipulation
The study highlights the superior performance of deep learning models, including CNN, RNN, and LSTM, in detecting DSCP-based traffic prioritization manipulations. These models are capable of identifying subtle and dynamic anomalies that rule-based systems often miss, providing a robust solution for network security.
Proactive Threat Mitigation
The developed models enable real-time detection of malicious DSCP alterations, which can be exploited for unfair bandwidth allocation or denial-of-service attacks. This proactive capability allows network administrators to mitigate threats before they impact critical services, enhancing overall network resilience.
Ensuring Fair QoS and Performance
By accurately identifying DSCP manipulations, the system ensures that Quality of Service (QoS) policies are enforced as intended. This guarantees fair bandwidth distribution for various traffic types (VoIP, video, etc.) and prevents performance degradation caused by unauthorized prioritization, leading to a more stable and efficient network.

DSCP Manipulation Scenarios & Impact
The study conceptualized several DSCP manipulation scenarios to demonstrate the detector's responses. For instance, 'Priority downgrades' (EF → AF41, EF → CS0) shift legitimate high-priority flows to lower classes, increasing latency and jitter. 'Priority enhancements' (CS0 → AF41, CS0 → EF) give best-effort traffic excessive bandwidth, causing throughput spikes. 'Cross-class remapping' (AF41 → EF, AF41 → CS0) alters packet forwarding methods, leading to localized delay variance. 'Random Bleaching' (DS field reverted to CS0) removes intended QoS semantics, resulting in inconsistent latency and jitter. Finally, 'Protocol-DSCP inconsistencies' (SRTCP/NTP marked CS0/CS6) indicate potential misconfigurations or circumvention. In all cases, the models effectively identified these manipulations, ensuring network integrity.
