用户数据包 meaning in English

user data packet

The " active " of active networks exhibit in two aspects : firstly , the resources of active network node are highly abstracted to a programmable network application programming interface . with this interface , the functionality of network nodes can be dynamically constructed and refined , and it could provide the more rich process capability with the packets . on the other hand , some executable programs are carried in user packets , which can execute in network nodes and change the network ' s behaviors as seen by user
主动式网络的“主动性”表现在两个方面：首先，在主动式网络中，结点资源(包括计算处理，缓存以及传输资源)被高度抽象为一种可编程的网络应用编程接口，通过这一网络应用编程接口，网络结点所具备的处理能力可以动态的扩展，更新和增强，它能够提供对流经的用户数据流进行高层复杂的计算处理能力；其次，用户数据包中能够携带可以在主动式结点中运行的程序代码，利用这一方式，用户可以对网络进行编程，在网络中灵活定制其所需的网络业务和应用，提供它们对自身特定数据进行处理的功能。
