基于网络的应用识别(NBAR)技术是Cisco公司内容网络结构的重要组成部分,它为解决网络QoS问题提供了一条途径。识别应用流听起来是很容易实现的技术,然而当今网络大多是基于Internet和客户端—服务器模式的,这就使得我们很难正确识别出所需要的控制层次。内容识别技术可以识别用户对特殊内容的 Network-based application identification (NBAR) technology is an important part of Cisco’s content network architecture, which provides a way to address network QoS issues. Identifying application streaming sounds like an easy-to-implement technology, but today’s networks are mostly based on Internet and client-server models, which makes it difficult to correctly identify the level of control we need. Content recognition technology can identify users to special content
