Client supplies complete Graphic User Interface, accomplishing the management of JobFlow and system. Communication agent accomplishes complete communication between client and server by TCP/IP network communication protocol and platform independent data communication protocol. Server supplies full support of JobFlow. The superstratums are the JobFlow Definition Subsystem and JnwEngine, which are responsible for the definition and execution of JobFlow. The understratum is the Network Queue System , which realizes the schedule and execution of job, thus all kinds of resources in computer network system can be utilized in order to improve execution efficiency and reduce job cost.

客户端提供完全的GUI用户界面，完成用户对作业流的管理及对系统的管理功能；通讯代理采用TCP／IP网络通信协议以及与平台无关的数据通讯协议来实现客户与服务器之间的完全通讯；服务器端提供对作业流的全面支持，上层由作业流定义子系统和作业流引擎负责完成对作业流的定义与执行，底层使用网络队列系统来实现对作业的调度与执行，使用户能够最大限度地利用计算机网络系统中的各种资源，以提高执行效率、降低作业成本。

The aim of protocol conformance testing is to verificate the conformance between computer network communication protocol implementation and correlative protocol criterion. And, it is the key to insure the correct connection and communication among all kinds of computer systems.

协议一致性测试是用来验证计算机网络通信协议的实现与相应的协议标准之间的一致性，是确保各种计算机系统正确互连和互操作的关键。

In order to get useful data, it researches the network sniffing technology based on Raw Socket and mainly studies the technology of protocol analyze and data recombine. And it introduces the Trojan horse technique to the network data collection part, improves the process hiding technique, uses the triple-thread technique, and so on. It ensures the imperceptibility and stability of the network data collection part. Then this paper develops pseudo hypertext transfer protocol based on HTTP. This protocol is used in the communication between the network data collection part and the service part, which make the communication more covert.
