Comparative analysis of related algorithms.

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.

哈希碰撞与负载重定向是当前哈希IP（Hash IP）算法的主要局限。为解决该问题，我们提出一种应用于网络负载均衡（Network Load Balancing，简称NLB）的新型哈希IP算法HDW，旨在提升网络的运行效率、可用性与可扩展性。我们通过将该算法与加权调度器（Weighted Scheduler，简称WS）技术及动态路由路径切换（Dynamic Switching of Routing Path，简称DSP）进行建设性融合，实现了这款新型哈希IP负载均衡方案。该方案不仅能够降低时延与网络抖动，同时依托哈希处理过程，还可提供一定程度的安全保障。经全面仿真实验与性能评估后的研究结果表明，相较于软件定义网络（Software Defined Network，简称SDN）领域的其他同类负载均衡算法，我们提出的HDW算法具备更优异的综合性能。
