摘 要
随着互联网的迅猛发展，网络应用日益多样化且对服务质量(QoS)的要求愈发严苛，传统网络难以满足实时性、可靠性等多方面需求，因此研究网络工程中的QoS保障技术具有重要意义。本研究旨在探索有效的QoS保障技术以应对复杂网络环境下的多种挑战。通过深入分析现有网络架构与协议机制，结合数学建模、仿真模拟以及实际网络测试等多种方法，重点研究了资源分配算法优化、流量调度策略改进和拥塞控制机制增强等方面内容。在资源分配方面提出了一种基于权重因子的动态调整算法，能够根据业务类型及优先级灵活分配带宽资源；针对流量调度设计了多路径负载均衡方案，有效提高了数据传输效率并降低了延迟；对于拥塞控制引入了预测性调节机制，提前感知潜在拥塞风险并及时采取措施避免拥塞发生。

Abstract
With the rapid development of the Internet, network applications are increasingly diversified and the requirements for service quality (QoS) are increasingly stringent, and the traditional network is difficult to meet the needs of real-time, reliability and other aspects, so it is of great significance to study the QoS guarantee technology in network engineering. This study aims to explore effective QoS safeguard technologies to address multiple challenges in a complex network environment. Through in-depth analysis of the existing network architecture and protocol mechanism, combined with mathematical modeling, simulation and actual network testing methods, the resource allocation algorithm optimization, traffic scheduling strategy improvement and congestion control mechanism enhancement are emphasized. In terms of resource allocation, a dynamic adjustment algorithm based on weight factor is proposed, which can flexibly allocate bandwidth resources according to service type and priority; a multi-path load balancing scheme is designed for flow scheduling, which effectively improves the data transmission efficiency and reduces the delay; introduces a predictive regulation mechanism for congestion control to perceive potential congestion risk in advance and take timely measures to avoid congestion.
