计算机网络需要复杂的控制机制来实现用户之间的公平资源分配以及有效的资源使用。为了在网络中成功地实现公平的资源分配，必须考虑到公平性来控制每个用户的行为。为了提供有效的资源利用，应该有人通过考虑效率来控制所有用户的行为。为了同时实现两种不同粒度的控制目标，提出了一种结合微观控制（即，公平性控制）和宏观控制（即，效率控制）。在以前的工作中，Aida提出了基于混沌的分层网络控制的概念。接下来，作为基于混沌的概念的应用，Aida设计了基于耦合弛豫振荡器的混沌的分级传输速率控制的基本框架。为了阐明基于混沌的概念的实现，应该足够详细地指定基于混沌的分层传输速率控制以在实际网络中工作，并确认其按预期工作。在这项研究中，我们实现了基于混沌的分层传输速率控制在一个流行的网络模拟器，ns-2，并通过我们的实验确认其操作。结果表明，基于混沌的概念可以成功地实现在TCP/IP网络。关键词：混沌，分层网络结构，拥塞控制，TCP全局同步，TCP（传输控制协议），RED（随机早期检测）
Computer networks require sophisticated control mechanisms to realize fair resource allocation among users in conjunction with efficient resource usage. To successfully realize fair resource allocation in a network, someone should control the behavior of each user by considering fairness. To provide efficient resource utilization, someone should control the behavior of all users by considering efficiency. To realize both control goals with different granularities at the same time, a hierarchical network control mechanism that combines microscopic control (i.e., fairness control) and macroscopic control (i.e., efficiency control) is required. In previous works, Aida proposed the concept of chaos-based hierarchical network control. Next, as an application of the chaos-based concept, Aida designed a fundamental framework of hierarchical transmission rate control based on the chaos of coupled relaxation oscillators. To clarify the realization of the chaos-based concept, one should specify the chaos-based hierarchical transmission rate control in enough detail to work in an actual network, and confirm that it works as intended. In this study, we implement the chaos-based hierarchical transmission rate control in a popular network simulator, ns-2, and confirm its operation through our experimentation. Results verify that the chaos-based concept can be successfully realized in TCP/IP networks. key words: chaos, hierarchical network architecture, congestion control, TCP global synchronization, TCP (transmission control protocol), RED (random early detection)
