MTU boyutu ağ performansını doğrudan etkiler; büyük MTU’lar protokol yükünü azaltıp işlemci üzerindeki yükü hafifletebilirken, uyumsuz ağlarda parçalara bölünmeye ve gecikmeye yol açabilir. Bu çalışmada, 802.3ad ve Round-Robin bağlantı birleştirme modlarının farklı MTU değerleri (450–9200 bayt) altında, tekli ve paralel veri akışı testleriyle performansı değerlendirilmiştir. Çok çekirdekli sistemlerde işlemci çekirdek kullanımı ve veri aktarım hızı analiz edilmiştir. Sonuçlar, Round-Robin modunun paralel akışlarda daha yüksek tepe verim sağlasa da işlemci kullanımında dengesizlik yarattığını ve uzun vadeli kararlılığı olumsuz etkilediğini göstermektedir. Öte yandan, 802.3ad modu daha dengeli işlemci yükü dağılımı ve tutarlı veri aktarım performansı ile yüksek verimli ve sürdürülebilir ağ ortamları için daha uygun bir çözüm sunmaktadır. Bu çalışma, modern ve gecikmeye duyarlı ağ tasarımlarında MTU farkındalığı olan, işlemci dostu bağlantı birleştirme stratejilerinin önemini vurgulamaktadır.

Investigation of Performance Impact of 802.3ad and Round-Robin Bonding Modes Under Different MTU Configurations

Öz

MTU size plays a crucial role in performance, where larger MTUs reduce protocol overhead and CPU load but may cause fragmentation and latency in heterogeneous networks. This study evaluates the performance of 802.3ad and Round-Robin bonding under varying MTU values (450–9200 bytes) across single and parallel stream tests. CPU core utilization and throughput metrics were analyzed to assess efficiency in multi-core systems. Results show that although Round-Robin achieves higher peak throughput in parallel streams, it leads to significant CPU imbalance and potential instability. In contrast, 802.3ad ensures better CPU load distribution and consistent throughput, making it more suitable for long-term, high-performance environments. The study highlights the need for MTU-aware, CPU-efficient bonding strategies in modern, latency-sensitive network designs.
