Overseas email delivery must not only overcome network latency issues but also navigate complex geopolitical network environments. Traditional direct overseas delivery methods often encounter connection timeouts, firewall blocking, and high delivery latency. At the same time, interoperability between domestic email systems and overseas networks also presents technical challenges.</p> <p>To address these issues, we designed and implemented a Smart Delivery Network (SDN) architecture that effectively improves the efficiency and reliability of overseas email delivery through multi-level proxying, intelligent routing, and load balancing mechanisms.</p>/en/archives/10-tcp-ip-osi/Tue, 24 Feb 2015 00:00:00 +0000/en/archives/10-tcp-ip-osi/<p>Network communication is the cornerstone of modern information technology, and understanding how network protocols work is crucial for every developer and system administrator. This article uses the OSI model framework to provide a detailed introduction to the distribution and roles of each protocol in the TCP/IP protocol suite within the network layer hierarchy.</p> <h2 id="what-is-the-osi-model">What is the OSI Model?</h2> <p>The OSI (Open Systems Interconnection) model is a conceptual network model that divides the network communication process into seven layers. Although this model is less popular in practice than the TCP/IP model, it is very helpful for understanding how network protocols work.</p>
