Instead of prioritizing bandwidth allocation, users can inexpensively overprovision band-width when they need to support delay-sensitive traffic such as voice and video. Also, simple mechanisms such as setting 802.1p bits on ethernet frame or type-of -service bits in IP headers are enough for LAN QOS.
Nonetheless, there 's still a huge demand among enterprise users for directories to enable self-configuring networks based on business policy.
DEN for QOS may still apply for WAN applications, edholm says. Indeed cisco has made more strides with DEN in the service provider market than in the enterprise arena.
Service providers are looking to DEN to integrate multivendor products into an interoperable operational support system.
So despite the silnece, progress on DEN is being the silnece, progress on DEN is being made and activty is expected to pick up once standards become a little more solidiffed.
今年三月，DETF 宣布完成了新版公共信息模型（CIM）的研究工作，此模型实现了CIM模式映射到简便目录访问协议（LDAP）的相应目录中，CIM 定义如何在目录中表示网络设备，系统和应用数据，因而它很容易为DEN 和企业管理目的而被共享。
