Proposal Number 0203876Title: "Smart Event Models and Architectures"Gail E. Kaiser, Columbia UniversityThis project investigates wide-area publish/subscribe event system models and architectures. The focus is on two new models called Smart Events and Active Events, and an event bus architecture called Virtual Private Event Networks (VPENs).Smart events are associated with a structural type model (a grammar or schema), and a semantic model that defines the processing to be performed on the structural subcomponents. Smart events are routed via content-based messaging, where subscriptions may specify complex patterns indicating the events of interest. Active events include their semantic model directly as mobile code. Active events operate asmobile agents transported (conceptually) under their own power point-to-point. Smart events may optionally include active event substructures, enabling content-based messaging to be applied to this subset of active events.VPENs extend multi-protocol label switching (MPLS) protocols and mechanisms to the application layer, to improve the performance of content-based routing by preplanning label switched paths when publisher advertisements as well as consumer subscriptions are available. VPENs also add encryption-based security and privacy in the style of virtual private networks (VPNs).

提案编号 0203876 标题：“智能事件模型和架构”Gail E. Kaiser，哥伦比亚大学该项目研究广域发布/订阅事件系统模型和架构。 重点是称为智能事件和活动事件的两个新模型，以及称为虚拟专用事件网络 (VPEN) 的事件总线架构。智能事件与结构类型模型（语法或模式）以及定义的语义模型相关联。对结构子组件执行的处理。 智能事件通过基于内容的消息传递进行路由，其中​​订阅可以指定指示感兴趣事件的复杂模式。活动事件直接将其语义模型包含为移动代码。活动事件作为移动代理（概念上）在其自己的电源点对点传输下运行。 智能事件可以选择包括活动事件子结构，从而使基于内容的消息传递能够应用于该活动事件子集。VPEN 将多协议标签交换 (MPLS) 协议和机制扩展到应用层，以提高基于内容的消息传递的性能当发布者广告和消费者订阅可用时，通过预先规划标签交换路径来进行路由。 VPEN 还以虚拟专用网络 (VPN) 的方式添加基于加密的安全性和隐私性。
