代理技术提供对应用层的保护能力，可是网络处理性能较低，无法满足日益增长的网络用户需求。
Although proxy technology is able to protect application, its performance on network process is lower, so it can't satisfy more and more requirement from network user.
根据进程对中不同进程的功能，模型分为代理传输层和用户接口层。
According to the function of the different process in process Pair, the model is divided into Agent Transfer Layer and User Interface Layer.
为了降低用户界面层，感知控制代理层以及功能核心层之间的耦合度，该模型还在它们之间分别加入了用户任务数据总线与应用领域数据总线。
In addition, the model using the user task date bus and application domain date bus to reduce the coupling between the user interface and function core.
