| With the development and popularization of the network communication of computer, constructing an electronic workbench with strong flexibility and dependability for enterprise's users, and utilizing many ways to promote the Exchange and communicate inside and outside enterprises to combine enterprise resources, it becomes possible to use it to improve the efficiency of working.According to the current situation of market and customer's demand,the article has proposed and realized the new instant electronic workbench of enterprise.This designs, based on advanced framework technology of software,integrated enterprise's institutional framework, enterprise's routine and instant message, short information of cell phone,video conference,Email system,sharing file system,IP phone, the fax through internet,information consultation,etc,together organically,Constructing new cooperative mode and exchange channel for the customer. As one outstanding infrastructure middleware,ACE (Adaptive Communication Environment) has already been used in the software development of the network extensively,It offers a series of Object-Oriented frames, and realize a lot of kernel patterns used for erupting the communication software simultaneously, the complexity of organizing in project of simplifying that can be great, accelerate the project process. So it is the best choice. At first, the base theory of ACE and Pattern is introduced and the necessity and advantages of the combination between ACE and Pattern is discussed. As the key tache of the combination,how to select the the corresponding pattern are narrated in the article.In the article,a Flexible and high-efficient distributed C/S systematic frame is designed.The system have three parts:server,service provider and client,the artice describes their detailed project of design and their Technological details.finally,the article introduces the technology of thorough NAT in P2P,and the technical realization of improvement bandwidth.
