Outline of Final Research Achievements |
Network latency is directly related to user experience of network applications. We have been proposed LAWIN (Latency AWare Internet) architecture, which satisfies various latency requirements from different applications. To demonstrate the feasibility of LAWIN in backbone networks, we implemented a hardware packet scheduler using FPGA. It performed bandwidth throughputs comparable to ordinary hardware based packet schedulers. To demonstrate the replaceability from the existing Internet, we evaluated the impact of LAWIN to existing traffic with real systems. We confirmed the impact to traffic behavior is negligible.

Academic Significance and Societal Importance of the Research Achievements |
本研究が目指すアプリケーションごとの遅延要求に応えるインターネットが実現すればアプリケーション体感品質の向上だけではなく、IoT (Internet of Things)では、取得したデータをもとに制御をおこなうセンサーからアクチュエータにいたる処理における実時間性の向上も期待できるなどその波及範囲は大きい。
