基于CORBA的分布式Agent通信构架

随着Internet的不断发展，传统的搜索引擎在信息获取上显露出明显的不足。Agent技术的出现使得个性化的主动信息服务成为可能，但是单个Agent的能力有限，因此需要在Agent之间进行通信与交流，实现社会过滤以提高信息服务的质量，为了解决Agent的运行平台和底层通信机制的异构性问题，提出了基于公用对象请求代理体系结构CORBA的分布式Agent通信构架－－CADA.Agent获取用户的信息需求并用KQML进行描述，它通过通信器与其他Agent进行信息交流，通信器对接收到的服务请求进行过滤，将其转发到能够提供该服务的Agent，最后把处理结果返回给客户端．CADA屏蔽了运行平台和底层通信机制，能够有效地解决分布式Agent的通信问题。

COMMUNICATION ARCHITECTURE OF DISTRIBUTED AGENTS BASED ON CORBA

As the Internet grows, traditional information search engines show many demerits in information retrieval. However, agent technology has strike out a broad way to provide personal and active information service. Since the ability of a single agent is limited, agents should communicate and cooperate with each other to increase the quality of information service. To address the communicate problem under heterogeneous environments and different communication mechanisms, this paper presents CADA the Communication Architecture of Distributed Agents based on CORBA. Agent describes users' information requests with KQML (Knowledge Query and Manipulation Language) and exchanges information with other agents through communicator. Communicator filters the information request and forwards it to the agent that can provide the service. Finally it sends the result or the exception to the client side. CADA provides a communication platform for distributed agents and shows a wide prospect.
