为了不断满足对带宽的需求和用户的需要,人们一直在努力寻找各种解决办法。现在,基于策略的网络使得不必增加网络的带宽,网络管理员就可以更加有效地使用目前的网络带宽。根据Yankee 8月份公布的最新研究报告《基于策略的网络和DEN》,厂商已经开始在他们的产品,例如路由器、交换机和远程访问服务器里采用基于策略的网络和目录激活网络(DEN,Directory-Enabled Network),所以不久他们就可以从QoS、安全和配置管理中获得好处。目录激活网络使用单个的目录结构把用户、应用程序和服务集成在一起,这种目录结构提供了唯一的管理。一个典型的DEN需要网络目录、策略服务器、网络管理系统和一个DEN能够识别的设备,这个设备用于加强策略。轻型目录访问 In order to continuously meet the demand for bandwidth and the needs of users, people have been trying hard to find various solutions. Policy-based networks now eliminate the need to increase network bandwidth and allow network managers to use current network bandwidth more efficiently. According to Yankee’s latest research report, “Policy-Based Networking and DEN,” released in August, vendors have begun adopting policy-based networks and directory activation networks (DEN, Directory-Enabled) in their products such as routers, switches and remote access servers Network, so soon they can benefit from QoS, security, and configuration management. Directory Activation Network uses a single directory structure to integrate users, applications and services together. This directory structure provides unique management. A typical DEN requires a network directory, a policy server, a network management system, and a device that DEN can recognize, which is used to enforce the policy. Lightweight directory access
