Research and Verification of Deterministic Transmission for E2E Traffic between Different Networks

In the context of the booming development of information technology today, many businesses have increasingly high demands for network latency, data integrity, and transmission reliability. The need for end-to-end high-quality data transmission is becoming more urgent. However, existing IP networks face challenges in ensuring deterministic transmission of services, which may lead to network congestion and data loss, negatively impacting the user experience. Despite the proposal and application of some deterministic network technologies, the application of these technologies still faces certain limitations. To address the aforementioned issues, this paper proposes an end-to-end deterministic transmission solution that comprehensively applies relevant technologies from TSN and DetNet to achieve end-to-end deterministic assurance. We construct an end-to-end deterministic network experimental environment and validate it by carrying various types of business traffic. The experimental results indicate that, under full load transmission of business flows and background flows, the proposed solution can significantly reduce the packet loss rate, stabilize latency, and minimize jitter, thereby achieving end-to-end deterministic transmission assurance.
