Agent通信机制探讨 总被引:25,自引:2,他引:25
Agent通信是多Agent系统的核心活动之一,是Agent相互协调、合作、竞争和完成任务的基础。Agent通信语言为此提供了一种高层次的、灵活、通用的通信模式。基于目前的KQML和FIPA-ACL,文章提出通用Agent通信语言的概念,给出一个递进式Agent通信模型和相应的语义描述,力图促进Agent通信的标准化和提高Agent通信的能力和效率。 相似文献

Agent通信语言综述 总被引:14,自引:0,他引:14
作为Agent间通信的关键,Agent通信语言(AgentCommunicationLanguage,ACL)已经得到学术界和企业界的广泛研究。在综合分析国内外有关ACL文献的基础上,总结了ACL的起源和发展,设计了ACL的基本框架;并在此框架基础上,分析比较了各种ACL,尤其对两种主流ACL:KQML(KnowledgeQueryandManagementLanguage)和FIPAACL(TheFoundationforIntelligentPhysicalAgentsACL)进行比较分析,最后对ACL研究热点做了总结,概括了可能的进一步研究方向。 相似文献

传统的Agent通信采用紧耦合方式,不利于多Agent系统的扩展和异质Agent之间的互操作.分析了Web服务和语义Web服务的基本模型,借鉴了语义Web服务的体系结构思想和实现手段,在此基础上给出了一个松散耦合的多Agent通信框架.框架强调慎思式多Agent之间合作的起点是Agent对自身能力的描述和发布,通过语法封装和语义映射解决使用不同ACL(Agent通信语言)的Agent交互问题,具有灵活性、可扩展性、简单性和通用性. 相似文献

提出一种基于模板分析方法,说明Agent之间通信如何使用这种方法去构造和分解消息,并说明这种方法减少了在ACL上的假设和消息格式的使用。模板的应用降低了Agent之间相互操作的需求,允许Agent在一个开放的多Agent系统中通信,可以事先不考虑缺少ACL协议和消息格式要求。 相似文献

Agent平台之间通过公共通信设施进行通信。Agent和通信服务协议自身不提供加密和签名等功能,这给Agent的通信带来了威胁。SSL是一种在客户端和服务器端建立安全通道的协议,通过对SSL协议的分析,认为SSL的加密套件与身份认证安全机制可以为Agent平台之间的通信提供安全通道,提出了将SSL协议架设在Agent平台之下通信协议之上的安全通信方案,给出了基于SSL协议的Agent通信代码,保证了Agent平台间的通信安全。 相似文献

移动Agent系统通信失效问题研究 总被引:8,自引:0,他引:8
The Mobile Agent is thought to be the popular computing model for the next generation's distributed sys-tem. The mobile agent has the following key features: autonomy, collaboration, security and especially mobility. Agood communication model for mobile agents cooperation is also necessary. In this article, after describing the maincommunication mechanisms, we analyze the methods to solve Agent Tracking and Communication Failure and make classification. We also propose a reliable and efficient mechanism named MEFS which uses Detecting methods and then analyze its performance by giving the experimental data at the end. 相似文献

David Kinny 《New Generation Computing》2001,19(2):139-156
It is well recognized that Agent Communication Languages (ACL’s) are critical elements of Multi-Agent Systems and a key to
their successful application in commerce and industry. The established field ofprotocol engineering, which concerns itself with how to specify machine communication languages and protocols, verify their properties and validate
implementations thereof, has developed powerful, theoretical and practical techniques for doing so, and a mature understanding
of the essential requirements that such specifications should meet. Regrettably, this body of knowledge and practice appears
to have had little influence on recently proposed ACL standards. For example, the latest ACL specifications proposed by the
Foundation for Intelligent Physical Agents (FIPA) are a confusing mix of different formal and informal specification techniques
whose net result is ambiguous, inconsistent and under-specified. Allowances must be made, as these are still draft specifications,
but rather than providing a verified foundation for reliable communication between heterogeneous agents, they run the risk
of leading to unreliable or incompatible implementations, or of being ignored in favour of more pragmatic and robust approaches.
In this paper, we propose a set of basic requirements which an ACL specification should meet, describe how the FIFA ACL measures
up against these, and contrast its features with those of a small ACL which was designed with reliability and ease of verification
as prime objectives.

基于Agent的坦克分队CGF中的通讯机制研究 总被引:4,自引:1,他引:3
坦克分队CGF中通讯机制的研究是CGF研究的主要课题,也是目前研究的难题。该文充分利用Agent建模与仿真技术的优势,在分析了坦克分队CGF通讯系统所应具有的层次结构和通讯仿真需求的基础上,首次提出了利用Agent的KQML(Knowledge Query and Manipulation Language)通信语言实现坦克分队CGF中各种实体之间的交互通信与信息传递,并就一种对话模式的坦克智能体之间的通讯机制进行了构建,为在坦克分队CGF仿真开发中通讯机制有效性、可靠性、透明性的提高提供右力的参考。 相似文献
