Hash collisions and redirection of loads are major limitations for recent Hash IP algorithms. To overcome this, we propose a new Hash IP algorithm dubbed HDW in network load balancing (NLB) to increase network’s efficiency, availability and scalability. We achieve the new Hash IP load balancing algorithm via a constructive merger with weighted scheduler (WS) technique and dynamic switching of routing path (DSP). This helps to reduce delays, jitters and additionally assures some level of security owing to the hashing process. Our findings after comprehensive simulations and performance evaluation depicts that our proposed HDW algorithm is relatively efficient as against other related load balancing algorithms for software defined network.哈希冲突与负载重定向是近期哈希IP（Hash IP）算法面临的核心局限。为破解这一难题，我们在网络负载均衡（Network Load Balancing, NLB）场景中提出了一种命名为HDW的新型哈希IP算法，旨在提升网络的运行效率、可用性与可扩展性。该算法通过将加权调度器（Weighted Scheduler, WS）技术与路由路径动态切换（Dynamic Switching of Routing Path, DSP）技术进行建设性融合，实现了新型哈希IP负载均衡方案。这一设计不仅能够有效降低时延与网络抖动，同时借助哈希处理流程额外提供了一定程度的安全保障。经全面仿真与性能评估后所得研究结果显示，相较于软件定义网络（Software Defined Network）场景下的其他同类负载均衡算法，本文所提出的HDW算法具备更优异的综合效率表现。
